`fallback-version = "0.0.0"` +- Verify tag matches pattern: `viscy-transforms-v0.1.0` for `pattern-prefix = "viscy-transforms-"` +**Warning signs:** Version shows as 0.0.0 when you expect something else + +### Pitfall 2: py.typed Not Included in Wheel +**What goes wrong:** Type checkers ignore package types despite py.typed file existing +**Why it happens:** Hatchling doesn't automatically include all non-Python files +**How to avoid:** Use `packages = ["src/viscy_transforms"]` which includes the entire directory +**Warning signs:** `mypy` or `pyright` shows "missing type stubs" for your own package + +### Pitfall 3: Package Name vs Import Name Mismatch +**What goes wrong:** `pip install viscy-transforms` but `import viscy_transforms` fails +**Why it happens:** PyPI package name uses hyphen, Python import uses underscore +**How to avoid:** Directory must be `viscy_transforms` (underscore), pyproject.toml `name` can be `viscy-transforms` (hyphen) +**Warning signs:** ModuleNotFoundError after successful install + +### Pitfall 4: Lock File Version Staleness +**What goes wrong:** `uv.lock` shows old version even after new tag +**Why it happens:** Dynamic versions are computed at install time, lock file is a snapshot +**How to avoid:** This is expected behavior; version in .venv will be correct +**Warning signs:** Lock file version doesn't match `uv pip show viscy-transforms` + +### Pitfall 5: Workspace Dependency Not Installed +**What goes wrong:** `uv sync` doesn't install workspace member dependencies +**Why it happens:** Missing `tool.uv.sources` configuration for workspace member +**How to avoid:** For workspace-internal deps, add `[tool.uv.sources] member = { workspace = true }` +**Warning signs:** ImportError for workspace member packages + +### Pitfall 6: Build Backend Type Coercion (v0.9.0+) +**What goes wrong:** uv-dynamic-versioning fails with type errors +**Why it happens:** Since v0.9.0, TOML types must be exact (no auto-coercion)

wrong:** Tests still import from `viscy.transforms` instead of `viscy_transforms` +**Why it happens:** Copy-paste without find-replace +**How to avoid:** Use systematic find-replace: `from viscy.transforms` -> `from viscy_transforms` +**Warning signs:** ModuleNotFoundError in test runs + +### Pitfall 3: Missing Module-Level __all__ +**What goes wrong:** `from viscy_transforms import *`

signs:** Unexpected symbols in package namespace + +### Pitfall 4: Kornia Import in _gaussian_smooth.py +**What goes wrong:** `filter3d_separable` is a module-level function, not a class +**Why it happens:** Easy to miss that it's exported in __init__.py as part of the module +**How to avoid:** Note that `_gaussian_smooth.py` exports `filter3d_separable` function +**Warning signs:** Test

The alls-green pattern solves the critical "skipped checks pass" problem in GitHub branch protection. prek is fully compatible with existing .pre-commit-config.yaml and offers faster execution than traditional pre-commit. + +**Primary recommendation:** Use setup-uv v7 with enable-cache for test matrix, alls-green for status check aggregation, uvx prek for linting, and pytest --cov-report=term-missing for coverage output. + +## Standard Stack + +### Core + +| Library/Action | Version | Purpose | Why Standard | +|----------------|---------|---------|--------------| +| astral-sh/setup-uv | v7 | Install uv with caching in GitHub Actions | Official Astral action, built-in cache support, Python version management | +| re-actors/alls-green | release/v1 | Aggregate matrix job statuses for branch protection | Solves "skipped checks pass" problem, widely adopted pattern | +| prek | latest (via uvx) | Run pre-commit hooks faster | Rust-based, compatible with .pre-commit-config.yaml, 50% less disk space | +| pytest-cov | >=7.0.0 | Coverage reporting in pytest | Already in project dependencies, supports terminal output modes | + +### Supporting + +| Library/Action | Version | Purpose | When to Use | +|----------------|---------|---------|-------------| +| actions/checkout | v5 | Clone repository | Every workflow job | +| astral-sh/ruff-action | v3 | Alternative to prek for ruff-only linting | If only ruff checks needed (not recommended - prek covers more) | + +### Alternatives Considered (Locked - Not Using) + +| Standard | Alternative | Why Not Using | +|----------|-------------|---------------| +| setup-uv | actions/setup-python | setup-uv handles Python installation and provides uv integration | +| prek | pre-commit | prek is locked decision - faster, Rust-based | +| prek | j178/prek-action | Direct uvx prek preferred for control and consistency with local workflow | + +**Installation:** Built-in to GitHub Actions via `uses:` directives. + +## Architecture Patterns + +### Recommended Workflow Structure + +``` +.github/ +└── workflows/ + ├── test.yml # Test matrix + alls-green check job + └── lint.yml # Linting via uvx prek +``` + +### Pattern 1: Test Matrix with alls-green Status Check + +**What:** Run tests across Python version matrix, aggregate results via alls-green job +**When to use:** Always for test workflows with matrix strategy +**Example:** +```yaml +# Source: https://github.com/re-actors/alls-green, https://github.com/astral-sh/setup-uv +name: Test + +on: + push: + branches: [main] + pull_request: + branches: [main] + +concurrency: + group: ${{ github.workflow }}-${{ github.ref }} + cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }} + +jobs: + test: + runs-on: ${{ matrix.os }} + strategy: + fail-fast: true + matrix: + os: [ubuntu-latest, macos-latest, windows-latest] + python-version: ["3.11", "3.12", "3.13"] + steps: + - uses: actions/checkout@v5 + - uses: astral-sh/setup-uv@v7 + with: + python-version: ${{ matrix.python-version }} + enable-cache: true + - run: uv sync --frozen --all-extras --dev + working-directory: packages/viscy-transforms + - run: uv run --frozen pytest --cov=viscy_transforms --cov-report=term-missing + working-directory: packages/viscy-transforms + + check: + name: All tests pass + if: always() + needs: [test] + runs-on: ubuntu-latest + steps: + - uses: re-actors/alls-green@release/v1 + with: + jobs: ${{ toJSON(needs) }} +``` + +### Pattern 2: Lint Workflow with uvx prek + +**What:** Run pre-commit hooks via prek in CI +**When to use:** For linting/formatting checks +**Example:** +```yaml +# Source: https://github.com/j178/prek, https://docs.astral.sh/ruff/integrations +name: Lint + +on: + push: + branches: [main] + pull_request: + branches: [main] + +concurrency: + group: ${{ github.workflow }}-${{ github.ref }} + cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }} + +jobs: + lint: + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v5 + - uses: astral-sh/setup-uv@v7 + with: + python-version: "3.13" + enable-cache: true + - name: Run prek hooks + run: uvx prek run --all-files + - name: Check formatting + run: uvx ruff format --check . +``` + +### Pattern 3: Concurrency Control for PR Workflows + +**What:** Cancel in-progress runs when new push to same PR, but let main branch complete +**When to use:** All workflows triggered by push and pull_request +**Example:** +```yaml +# Source: https://docs.github.com/en/actions/how-tos/write-workflows/choose-when-workflows-run/control-workflow-concurrency +concurrency: + group: ${{ github.workflow }}-${{ github.ref }} + cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }} +``` + +### Anti-Patterns to Avoid + +- **No alls-green job:** Without this, skipped matrix jobs appear as "passing" in branch protection +- **cancel-in-progress: true on main:** Can cancel important main branch workflows;

Without src layout, `import viscy_transforms` might import local directory instead of installed package. + +**Configuration:** +```toml +# packages/viscy-transforms/pyproject.toml +[build-system] +requires = ["hatchling", "uv-dynamic-versioning"] +build-backend = "hatchling.build" + +[tool.hatch.build.targets.wheel] +packages = ["src/viscy_transforms"] +``` + +### Pattern 3: Workspace Dependencies via Sources + +**What:** Inter-package dependencies declared with `workspace = true`. + +**When:** Package A depends on Package B, both in workspace. + +**Why:** Ensures editable installs during development, proper resolution during publish. + +**Configuration:** +```toml +# packages/viscy-data/pyproject.toml +[project] +dependencies = ["viscy-transforms"] + +[tool.uv.sources] +viscy-transforms = { workspace = true } +``` + +### Pattern 4: Single Lockfile + +**What:** One `uv.lock` at workspace root, none in packages. + +**When:** Always. + +**Why:** Ensures consistent dependency versions across all packages. `uv lock` operates on entire workspace. + +**Commands:** +```bash +uv lock # Lock all packages +uv sync --package viscy-transforms # Sync specific package +uv run --package viscy-transforms pytest # Run tests for package +``` + +### Pattern 5: Git-Based Versioning with uv-dynamic-versioning + +**What:** Version derived from git tags, not hardcoded in pyproject.toml. + +**When:** Libraries distributed to PyPI. + +**Why:** Single source of truth for versions, automated release workflow. + +**Configuration:** +```toml +[project] +name = "viscy-transforms" +dynamic = ["version"] + +[build-system] +requires = ["hatchling", "uv-dynamic-versioning"] +build-backend = "hatchling.build" + +[tool.hatch.version] +source = "uv-dynamic-versioning" + +[tool.uv-dynamic-versioning] +vcs = "git" +style = "pep440" +# For monorepo: filter tags by package prefix +pattern = "^viscy-transforms-v(?P.*)$" +``` + +### Pattern 6: PEP 735 Dependency Groups + +**What:** Development dependencies in `[dependency-groups]` table, not optional-dependencies. + +**When:** Test, dev, docs dependencies. + +**Why:** PEP 735 standard, supported by uv, clear separation from runtime optional features. + +**Configuration:** +```toml +[dependency-groups] +test = [ + "pytest>=8.0", + "pytest-cov", + "hypothesis", +] +dev = [ + { include-group = "test" }, + "pre-commit", + "ruff", +] +``` + +### Pattern 7: Independent Package Testing + +**What:** Each package has its own tests directory and can be tested in isolation. + +**When:** Always. + +**Why:** Validates package independence, faster CI, clearer ownership. + +**Commands:** +```bash +# Test specific package +uv run --package viscy-transforms pytest packages/viscy-transforms/tests/ + +# Test all packages +uv run pytest +``` + +## Anti-Patterns to Avoid + +### Anti-Pattern 1: Flat Layout (No src/) + +**What:** `packages/viscy-transforms/viscy_transforms/__init__.py` + +**Why bad:** During development, Python may import local directory instead of installed package, hiding import errors that would appear for users. + +**Instead:** Use src layout: `packages/viscy-transforms/src/viscy_transforms/__init__.py` + +### Anti-Pattern 2: Per-Package Lockfiles + +**What:** `packages/viscy-transforms/uv.lock` + +**Why bad:** Breaks workspace benefits, dependency version conflicts between packages, CI complexity. + +**Instead:** Single lockfile at workspace root. + +### Anti-Pattern 3: Hardcoded Versions in pyproject.toml + +**What:** `version = "0.1.0"` in pyproject.toml + +**Why bad:** Manual version bumping, easy to forget, out of sync with git tags. + +**Instead:** `dynamic = ["version"]` with uv-dynamic-versioning. + +### Anti-Pattern 4: Root Package with Actual Code + +**What:** Distributable code in workspace root alongside `[tool.uv.workspace]`. + +**Why bad:** Confuses workspace coordination with package distribution, unclear responsibilities. + +**Instead:** Virtual workspace root (`package = false`), all code in `packages/`. + +### Anti-Pattern 5: Circular Dependencies Between Packages + +**What:** viscy-transforms depends on viscy-data, viscy-data depends on viscy-transforms. + +**Why bad:** Build order impossible, indicates poor separation of concerns. + +**Instead:** Identify common code, extract to lower-level package, maintain DAG. + +### Anti-Pattern 6: Mixing optional-dependencies and dependency-groups + +**What:** Using optional-dependencies for dev/test dependencies. + +**Why bad:** PEP 735 provides proper standard, optional-dependencies should be runtime features. + +**Instead:** Use `[dependency-groups]` for dev/test, `[project.optional-dependencies]` for runtime features like `viscy-transforms[gpu]`. + +## Build Order for Setup Tasks + +Based on dependencies between setup tasks, recommended execution order: + +```

You can't just copy `uv.lock` and install third-party deps without the package sources. + +**Prevention:** +- Use `uv sync --frozen --package ` which resolves from lockfile alone (partially works) +- Structure Dockerfiles to copy minimal files first, then add sources +- Consider `--no-editable` flag when available for self-contained builds + +**Detection:** Docker build times remain high even for unrelated changes. + +**Phase:** Address in Phase 4 (CI/CD optimization) or defer to later milestone. + +**Confidence:** MEDIUM (discussed in [uv issue #6935](https://github.com/astral-sh/uv/issues/6935)) + +--- + +### Pitfall 7: IDE Workspace Recognition Failures + +**What goes wrong:** VS Code/PyCharm don't understand uv workspace structure.

The recommended approach uses **hatchling + hatch-vcs + hatch-cada** for build and versioning, replacing the current setuptools + setuptools-scm configuration. The first extraction targets `viscy-transforms` (GPU augmentation transforms), establishing patterns for future extractions. + +The monorepo approach enables users to install only what they need (`pip install viscy-transforms` instead of the entire VisCy stack), reduces dependency bloat, and allows independent release cycles. Critical to success: agreeing on a single Python version floor (3.11+) across all workspace members, preventing import leakage via isolated testing, and using src layout to avoid development-time import confusion. The architecture requires careful dependency management since all packages share a single lockfile. + +Key risks center on the shared lockfile constraint (conflicting dependencies between packages break the workspace) and the clean break in import paths (`from viscy_transforms import X` not `from viscy.transforms import X`). Applications and examples will have temporarily broken imports until updated. Mitigation requires phase-gated extraction with validation at each step, comprehensive CI testing per package, and clear migration documentation for downstream users. + +## Key Findings + +### Recommended Stack + +The stack modernizes VisCy's tooling while maintaining compatibility with the scientific Python ecosystem. Core shift: **hatchling replaces setuptools** because it's extensible via plugins and integrates cleanly with uv workspaces. Dynamic versioning uses **hatch-vcs (git tag based) + hatch-cada (workspace dependency rewriting)** instead of setuptools-scm. This combination enables independent package versioning with tags like `viscy-transforms@1.0.0` while correctly handling inter-package dependencies at build time. + +**Core technologies:** +- **uv** (package manager, workspace orchestration) — 10-100x faster than pip, native workspace support, industry standard for 2025+ +- **hatchling + hatch-vcs + hatch-cada** (build system + versioning) — Plugin-based extensibility; hatch-cada critical for workspace deps; hatch-vcs mature git versioning +- **Zensical** (documentation) — Official successor to Material for MkDocs (now in maintenance mode); 4-5x faster builds; Rust + Python +- **ruff** (linting + formatting) — Replaces black + isort + flake8; 200x faster; native Jupyter support; current project already uses it + +**Note:** Cannot use uv's native build backend (`build-backend = "uv"`) because it doesn't support plugins yet.

Each package uses src layout (`packages//src//`) with its own pyproject.toml, preventing import confusion and enabling true independence. The single lockfile at workspace root ensures consistent dependency resolution, while workspace dependencies declared via `[tool.uv.sources]` with `workspace = true` enable editable development. + +**Major components:** +1. **Workspace Root** — Defines membership via `[tool.uv.workspace]`, shared tooling config (ruff, mypy, pytest), not installable itself +2. **viscy-transforms (first extraction)** — Image transformations (kornia, monai based); standalone with no workspace dependencies +3. **viscy-data (future)** — Data loading, HCS datasets; may depend on viscy-transforms via workspace sources +4. **viscy-models (future)** — Neural network architectures; may depend on viscy-transforms +5. **applications/** — Publication code (not a package); broken imports acceptable during transition + +**Critical path:** Workspace scaffolding → First package extraction → Code migration → Test migration. Phases 5+ (dependency groups) and 6 (dynamic versioning) can run in parallel after Phase 2 completes. + +### Critical Pitfalls + +1. **Single requires-python constraint** — uv enforces workspace-wide Python version intersection. If one package needs 3.12+, entire workspace becomes 3.12+. Users on 3.11 cannot install any package even if individually compatible. **Mitigation:** Agree on Python 3.11 floor upfront; document in workspace root; all packages must use `>=3.11`. + +2. **Conflicting dependencies between members** — All packages share one lockfile. If viscy-transforms needs `numpy<2` and a future package needs `numpy>=2`, resolution fails and workspace cannot lock. **Mitigation:** Survey dependency constraints before adding packages; pin compatible ranges for PyTorch/NumPy early; consider path dependencies for genuinely incompatible packages. + +3. **Import leakage between workspace members** — Python doesn't enforce dependency boundaries. viscy-transforms can accidentally import from viscy-data even without declaring it, because both are in the same environment. Works in monorepo, fails for users. **Mitigation:** Test each package in isolation (`uv sync --package `); CI must test packages independently, not just whole workspace. + +4. **uv-dynamic-versioning requires hatchling** — Using `build-backend = "uv"` breaks dynamic versioning; uv-dynamic-versioning is a hatchling plugin. **Mitigation:** Always use `build-backend = "hatchling.build"`; verify version in built wheel before publishing. + +5. **Entry points lost during migration** — CLI commands (`viscy = "viscy.cli:main"`) stop working after setuptools → hatchling. Different config syntax; easy to forget. **Mitigation:** Audit all `[project.scripts]` sections; test CLI after migration: `uv run viscy --help`. + +## Implications for Roadmap + +Based on research, suggested phase structure: + +### Phase 1: Workspace Foundation +**Rationale:** Establishes monorepo structure and prevents critical pitfalls (Python version floor, build system).

The scaffold follows the identical pattern established by `viscy-transforms` in v1.0: src layout, hatchling + uv-dynamic-versioning build system, PEP 735 dependency groups. The critical new work is component extraction -- identifying and isolating the 14+ shared nn.Module classes from `unext2.py` and related files into a `_components/` subpackage, plus migrating ConvBlock2D/3D to `unet/_layers/`. + +The source code lives in the pre-migration VisCy repo (tag `v0.3.3`). Key files are `viscy/unet/networks/unext2.py` (contains UNeXt2Stem, StemDepthtoChannels, PixelToVoxelHead, UnsqueezeHead, UNeXt2Decoder, UNeXt2UpStage, UNeXt2, and helper functions), `viscy/unet/networks/layers/ConvBlock2D.py` and `ConvBlock3D.py`, and `viscy/unet/networks/fcmae.py` (which imports shared components from unext2.py). The VAE models (`viscy/representation/vae.py` on commit c591950) also import `StemDepthtoChannels` and `PixelToVoxelHead` from unext2.py, confirming these are genuinely shared. The contrastive encoder (`viscy/representation/contrastive.py`) imports `StemDepthtoChannels`. This cross-model sharing validates the `_components/` extraction approach. + +Mutable defaults needing conversion to tuples exist in: `FullyConvolutionalMAE.__init__` (encoder_blocks, dims as lists), `Unet2d.__init__` (num_filters=[]), `Unet25d.__init__` (num_filters=[]), and `VaeDecoder.__init__` (decoder_channels, strides as lists). The UNeXt2 class itself uses immutable defaults already. State dict key compatibility is non-negotiable -- the module naming (`self.stem`, `self.encoder`, `self.decoder`, `self.head`, etc.) must be preserved exactly during extraction. + +**Primary recommendation:** Mirror the viscy-transforms scaffold exactly (pyproject.toml, src layout, test structure), extract shared components into `_components/{stems,heads,blocks}.py`, and migrate ConvBlock2D/3D into `unet/_layers/` with snake_case filenames.

Renaming breaks state dict keys. +- **Creating circular imports between _components and model subpackages:** `_components/` should have zero imports from `unet/`, `vae/`, or `contrastive/`. It should only import from torch, timm, monai, numpy. +- **Importing from viscy-transforms:** viscy-models must be independent of viscy-transforms. Only torch/timm/monai/numpy dependencies. +- **Putting model-specific code in _components:** Only truly shared code belongs in `_components/`. If something is used by only one model, keep it in that model's file. +- **Splitting ConvBlock into too many files:** conv_block_2d.py and conv_block_3d.py are sufficient. Do not over-decompose. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| ConvNeXt stages | Custom ConvNeXt blocks | `timm.models.convnext.ConvNeXtStage` | Pretrained weights, proven architecture, state dict compatibility | +| Upsampling blocks | Custom pixel shuffle | `monai.networks.blocks.UpSample` | Handles edge cases (padding, pre-conv), medical imaging validated | +| 3D ResNet features | Custom ResNet backbone | `monai.networks.nets.resnet.ResNetFeatures` | Pretrained MedicalNet weights, spatial_dims=3 support | +| Feature extraction backbone | Custom encoder | `timm.create_model(..., features_only=True)` | Access to 1000+ pretrained models, multi-scale feature maps | +| Dynamic versioning | Manual version management | `uv-dynamic-versioning` with `pattern-prefix` | Tag-based, monorepo-aware, proven by viscy-transforms | +| Build system | Custom build scripts | `hatchling` with `uv-dynamic-versioning` | Same as viscy-transforms, workspace-tested | + +**Key insight:** Every "shared" component in viscy-models wraps or extends third-party functionality (timm, monai). The extraction is about organizing imports and file structure, NOT reimplementing anything. + +## Common Pitfalls + +### Pitfall 1: State Dict Key Mismatch After Extraction +**What goes wrong:** Extracting a class to a new file and changing how models instantiate it (e.g., renaming `self.stem` to `self.projection_stem`) silently changes state dict keys, making all existing checkpoints unloadable. +**Why it happens:** PyTorch state dict keys are derived from the module hierarchy: `stem.conv.weight` comes from `self.stem = UNeXt2Stem(...)` which contains `self.conv = nn.Conv3d(...)`. +**How to avoid:** Keep module attribute names IDENTICAL. Only change the import path, never the attribute name or internal structure of extracted classes. +**Warning signs:** `model.load_state_dict(checkpoint)` raises `RuntimeError: Error(s) in loading state_dict` with "Missing key" or "Unexpected key" messages. + +### Pitfall 2: Import Cycles Between _components and Model Subpackages +**What goes wrong:** `_components/blocks.py` imports from `unet/unext2.py` which imports from `_components/stems.py`, creating a circular import. +**Why it happens:** `UNeXt2UpStage` and `UNeXt2Decoder` use `_get_convnext_stage` which is a utility, not a shared component. Putting model-specific utilities in `_components` tempts circular imports. +**How to avoid:** `_components/` must have ZERO imports from model subpackages (unet/, vae/, contrastive/). It should only import from torch, timm, monai, numpy. Functions like `_get_convnext_stage` and `icnr_init` that are used by both UNeXt2 and FCMAE belong in `_components/blocks.py`, but they must not reference any model classes. +**Warning signs:** `ImportError: cannot import name 'X' from partially initialized module`. + +### Pitfall 3: Mutable Default Shared State +**What goes wrong:** Two model instances share the same default list object. One mutant modifies it during `__init__`, corrupting the other. +**Why it happens:** Python evaluates default arguments once at function definition time, not at each call. +**How to avoid:** Replace all `= [...]` defaults with `= (...)` tuples. Convert to list internally if mutation is needed. +**Warning signs:** `ruff` rule B006 ("Do not use mutable data structures for argument defaults") catches this if linting is enabled. + +### Pitfall 4: Missing timm Dependency in Lockfile +**What goes wrong:** `uv sync --package viscy-models` fails or imports fail at runtime because timm is not in the workspace lockfile. +**Why it happens:** viscy-transforms does not depend on timm, so it is not in the current lockfile. Adding viscy-models with timm dependency requires `uv lock` to be re-run. +**How to avoid:** Run `uv lock` after adding the viscy-models pyproject.toml, before attempting `uv sync`. +**Warning signs:** `uv sync` fails with resolution errors or timm import fails at test time. + +### Pitfall 5: numpy Import in ConvBlock (Dependency Concern) +**What goes wrong:** ConvBlock2D and ConvBlock3D use `numpy.linspace` for filter step calculations. This is a runtime numpy dependency. +**Why it happens:** The original code used numpy for array math instead of pure Python or torch. +**How to avoid:** Keep numpy as a dependency (already declared). The usage is lightweight (only in `__init__`, not forward pass). +**Warning signs:** None, as long as numpy is in dependencies. Consider replacing with `torch.linspace` in a future cleanup, but not in scope for Phase 6. + +### Pitfall 6: ConvBlock register_modules Not Using nn.ModuleList +**What goes wrong:** ConvBlock2D/3D use custom `register_modules()` + `add_module()` instead of `nn.ModuleList`. This works but creates non-standard state dict keys like `Conv2d_0.weight` instead of `conv_list.0.weight`. +**Why it happens:** Legacy implementation predating PyTorch's nn.ModuleList improvements. +**How to avoid:** Do NOT refactor to nn.ModuleList during migration -- this would change state dict keys and break checkpoints. Preserve the `add_module` pattern exactly. +**Warning signs:** Any changes to module registration pattern will break `load_state_dict`. + +## Code Examples + +### Shared Component Categorization (from v0.3.3 source analysis) + +The following components from `unext2.py` are imported by multiple model files: + +**stems.py** -- Used by UNeXt2, ContrastiveEncoder, BetaVae25D, VaeEncoder, FCMAE: +```python +# Source: v0.3.3 viscy/unet/networks/unext2.py +class UNeXt2Stem(nn.Module): # Used by UNeXt2 +class StemDepthtoChannels(nn.Module): # Used by ContrastiveEncoder, VaeEncoder +``` + +**heads.py** -- Used by UNeXt2, FCMAE, BetaVae25D/VaeDecoder: +```python +# Source: v0.3.3 viscy/unet/networks/unext2.py, fcmae.py +class PixelToVoxelHead(nn.Module): # Used by UNeXt2, VaeDecoder, FCMAE (head_conv=True) +class UnsqueezeHead(nn.Module): # Used by future models that output 2D->3D +class PixelToVoxelShuffleHead(nn.Module): # Used by FCMAE (head_conv=False) +``` + +**blocks.py** -- Shared encoder/decoder building blocks and initialization: +```python +# Source: v0.3.3 viscy/unet/networks/unext2.py +def icnr_init(...): # Used by UNeXt2 stem init, _get_convnext_stage +def _get_convnext_stage(...): # Used by UNeXt2UpStage conv blocks + +class UNeXt2UpStage(nn.Module): # Used by UNeXt2Decoder +class UNeXt2Decoder(nn.Module): # Used by UNeXt2, FullyConvolutionalMAE + +# Source: v0.3.3 viscy/representation/vae.py (commit c591950) +class VaeUpStage(nn.Module): # Used by VaeDecoder +class VaeEncoder(nn.Module): # Used by BetaVae25D +class VaeDecoder(nn.Module): # Used by BetaVae25D +``` + +### Component Import Pattern (after extraction) +```python +# In packages/viscy-models/src/viscy_models/unet/unext2.py +from viscy_models._components.stems import UNeXt2Stem +from viscy_models._components.heads import PixelToVoxelHead +from viscy_models._components.blocks import UNeXt2Decoder +``` + +### ConvBlock Migration (unet/_layers/) +```python +# packages/viscy-models/src/viscy_models/unet/_layers/__init__.py +from viscy_models.unet._layers.conv_block_2d import ConvBlock2D +from viscy_models.unet._layers.conv_block_3d import ConvBlock3D + +__all__ = ["ConvBlock2D", "ConvBlock3D"] +``` + +### Mutable Defaults Inventory (COMPAT-02) + +All mutable defaults found in model constructors that must be converted: + +| File | Class | Parameter | Current Default | Fixed Default | +|------|-------|-----------|----------------|---------------| +| fcmae.py | FullyConvolutionalMAE | encoder_blocks | `[3, 3, 9, 3]` | `(3, 3, 9, 3)` | +| fcmae.py | FullyConvolutionalMAE | dims | `[96, 192, 384, 768]` | `(96, 192, 384, 768)` | +| fcmae.py | FullyConvolutionalMAE | stem_kernel_size | `(5, 4, 4)` | Already tuple -- OK | +| Unet2D.py | Unet2d | num_filters | `[]` | `()` | +| Unet25D.py | Unet25d | num_filters | `[]` | `()` | +| vae.py | VaeDecoder | decoder_channels | `[1024, 512, 256, 128]` | `(1024, 512, 256, 128)` | +| vae.py | VaeDecoder | strides | `[2, 2, 2, 1]` | `(2, 2, 2, 1)` | + +**Note:** Internal code that creates lists from these parameters (e.g., `list(dims)`) continues to work because tuples are iterable.

Not a shared component. + +2. **Should VaeUpStage/VaeEncoder/VaeDecoder go in _components/blocks.py or vae/?** + - What we know: VaeUpStage is similar to UNeXt2UpStage but lacks skip connections. VaeEncoder/VaeDecoder are only used by BetaVae25D. + - What's unclear: Whether they will be reused by future models. + - Recommendation: Keep VaeUpStage, VaeEncoder, VaeDecoder in `vae/` module (Phase 8 scope), not in `_components/`. They are specific to VAE architecture. Only truly cross-family components (stems, heads used by UNet+VAE+contrastive) belong in `_components/`. + +3. **Should FCMAE's masked operation functions go in _components/?** + - What we know: `generate_mask`, `upsample_mask`, `masked_patchify`, `masked_unpatchify` are only used by FCMAE classes. + - What's unclear: Whether future models will need masking operations. + - Recommendation: Keep in `unet/fcmae.py` (Phase 7 scope). Not shared. + +4. **Phase 6 scope boundary: empty model dirs vs. populated dirs?** + - What we know: Phase 6 requires _components/ and unet/_layers/ to be populated. Phases 7-9 migrate actual models. + - What's unclear: Should `unet/__init__.py`, `vae/__init__.py`, `contrastive/__init__.py` be created empty in Phase 6? + - Recommendation: Create the directory structure with empty `__init__.py` files in Phase 6.

Input (1,1,5,256,256). Conv3d output: D=(5-5)/5+1=1, H=(256-4)/4+1=64, W=(256-4)/4+1=64. Channels: out_channels//ratio = 96//1 = 96. Reshape: (1, 96*1, 64, 64) = (1, 96, 64, 64). Correct. +- `test_stem_depth_to_channels_output_shape`: Create `StemDepthtoChannels(in_channels=1, in_stack_depth=15, in_channels_encoder=96, stem_kernel_size=(5,4,4), stem_stride=(5,4,4))`. Input: `torch.randn(1, 1, 15, 256, 256)`. stem3d_out_depth = (15-5)//5+1 = 3, stem3d_out_channels = 96//3 = 32. Conv3d output: (1, 32, 3, 64, 64). Reshape: (1, 96, 64, 64). Assert output shape is `(1, 96, 64, 64)`. +- `test_stem_depth_to_channels_mismatch`: Assert that `StemDepthtoChannels(in_channels=1, in_stack_depth=10, in_channels_encoder=96, stem_kernel_size=(5,4,4), stem_stride=(5,4,4))` raises `ValueError` (because 96 is not divisible by stem3d_out_depth=2... actually (10-5)//5+1=2, 96//2=48, 48*2=96, mismatch=0. Use in_stack_depth=12 instead: (12-5)//5+1=2, same. Try in_stack_depth=7: (7-5)//5+1=1, 96//1=96, 96*1=96, OK. Try in_channels_encoder=97 with in_stack_depth=15: 97//3=32, 32*3=96, mismatch=1. Use `StemDepthtoChannels(in_channels=1, in_stack_depth=15, in_channels_encoder=97)` to trigger ValueError). + +**test_heads.py**: +- `test_pixel_to_voxel_head_output_shape`: Create a PixelToVoxelHead with representative params. Input shape must be 2D (B,C,H,W). The head is complex -- use params similar to UNeXt2's usage: `PixelToVoxelHead(in_channels=96, out_channels=2, out_stack_depth=5, expansion_ratio=4, pool=False)`. Input: `torch.randn(1, 96, 64, 64)`. Expected output: (1, 2, 5, 256, 256) -- the head upsamples 2x via pixelshuffle (64->128 in upsample), then 3D conv reduces depth from 7 to some value, then pixelshuffle 2x again. This is complex -- compute carefully or just verify output has 5 dims (B, out_channels, out_stack_depth, H', W') and channels match out_channels. Use a simpler assertion: `assert output.shape[0] == 1 and output.shape[1] == 2 and output.shape[2] == 5`. +- `test_unsqueeze_head`: Create `UnsqueezeHead()`. Input: `torch.randn(2, 16, 32, 32)`. Assert output shape is `(2, 16, 1, 32, 32)`. +- `test_pixel_to_voxel_shuffle_head_output_shape`: Create `PixelToVoxelShuffleHead(in_channels=768, out_channels=2, out_stack_depth=5, xy_scaling=4, pool=False)`. Input: `torch.randn(1, 768, 16, 16)`. Upsample: pixelshuffle 4x from (1, 768, 16, 16) -> (1, 5*2, 64, 64) = (1, 10, 64, 64). Reshape: (1, 2, 5, 64, 64). Assert output shape is `(1, 2, 5, 64, 64)`. + +**test_blocks.py**: +- `test_icnr_init`: Create a `nn.Conv2d(16, 64, 3, padding=1)`. Call `icnr_init(conv, upsample_factor=2, upsample_dims=2)`. Assert conv.weight is not all zeros and has expected shape. +- `test_get_convnext_stage`: Call `_get_convnext_stage(in_channels=96, out_channels=96, depth=2)`. Assert result is an `nn.Module`. Create input `torch.randn(1, 96, 32, 32)` and verify forward pass produces same spatial dims. +- `test_unext2_up_stage_pixelshuffle`: Create `UNeXt2UpStage(in_channels=192, skip_channels=96, out_channels=96, scale_factor=2, mode="pixelshuffle", conv_blocks=2, norm_name="instance", upsample_pre_conv=None)`. Input: `torch.randn(1, 192, 16, 16)` (low-res), skip: `torch.randn(1, 96, 32, 32)` (high-res). Verify output shape is `(1, 96, 32, 32)`. +- `test_unext2_decoder`: Create `UNeXt2Decoder(num_channels=[384, 192, 96], norm_name="instance", mode="pixelshuffle", conv_blocks=2, strides=[2, 2], upsample_pre_conv=None)`. Input features: `[torch.randn(1, 384, 8, 8), torch.randn(1, 192, 16, 16), torch.randn(1, 96, 32, 32)]`. The decoder processes high-to-low resolution. Verify output shape spatial dims are 32x32 and channels are 96. Note: features list has reversed order (largest channels first), and the last element is used as skip. Verify output is `(1, 96, 32, 32)`. + +Run all tests with: `uv run --package viscy-models pytest packages/viscy-models/tests/test_components/ -v` + + +`uv run --package viscy-models pytest packages/viscy-models/tests/test_components/ -v` passes all tests. +At least 8 tests total across the 3 test files. + + All _components have forward-pass tests verifying correct output shapes.

All shared components (stems, heads, blocks, decoder) were already extracted into `_components/` during Phase 6. The migration involves: (1) copying the model class code, (2) updating imports to point at `viscy_models._components` instead of the old monolithic `viscy.unet.networks.unext2`, (3) fixing two mutable list defaults in FCMAE's constructor, and (4) writing new tests for UNeXt2 (currently untested) and migrating 11 existing FCMAE tests. + +The UNeXt2 class is thin -- it composes a `timm.create_model` encoder with the already-extracted `UNeXt2Stem`, `UNeXt2Decoder`, and `PixelToVoxelHead`. A full forward pass through the composed pipeline has been verified to work with the Phase 6 extracted components (output: `(1, 2, 5, 256, 256)` from `(1, 1, 5, 256, 256)` input with `convnextv2_tiny` backbone). The FCMAE class contains 10 additional items (5 functions + 5 classes) for masked convolution that are FCMAE-specific and stay in `fcmae.py`. FCMAE imports `UNeXt2Decoder`, `PixelToVoxelHead`, and `PixelToVoxelShuffleHead` from `_components`, which are all available. State dict key compatibility is ensured by preserving module attribute names verbatim (`self.stem`, `self.encoder_stages`, `self.decoder`, `self.head` for UNeXt2; `self.encoder`, `self.decoder`, `self.head` for FCMAE). + +**Primary recommendation:** This is a straightforward copy-and-rewire migration. The critical discipline is not changing any module attribute names. The real new work is writing UNeXt2 forward-pass tests covering multiple configurations (varying backbone, channel counts, stack depths, decoder modes). + +## Standard Stack + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| torch | >=2.10 | nn.Module base, tensor ops | All models are nn.Module | +| timm | >=1.0.15 (installed: 1.0.24) | ConvNeXtV2 backbone, ConvNeXtStage, masked conv helpers | UNeXt2 uses `timm.create_model()`, FCMAE uses `timm.models.convnext.*` | +| monai | >=1.5.2 | UpSample, Convolution, ResidualUnit, get_conv_layer | Decoder and head upsampling blocks | +| numpy | >=2.4.1 | (indirect, via ConvBlock) | Not directly needed by UNeXt2/FCMAE, but in package deps | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| pytest | >=9.0.2 | Test framework | All model tests | + +### Alternatives Considered +None -- all libraries are locked from Phase 6 decisions. + +**Installation:** +```bash +uv sync --package viscy-models +``` + +## Architecture Patterns + +### Target File Structure After Phase 7 +``` +packages/viscy-models/src/viscy_models/ + _components/ # Phase 6: DONE + __init__.py + stems.py # UNeXt2Stem, StemDepthtoChannels + heads.py # PixelToVoxelHead, UnsqueezeHead, PixelToVoxelShuffleHead + blocks.py # UNeXt2UpStage, UNeXt2Decoder, icnr_init, _get_convnext_stage + unet/ + __init__.py # Phase 7: export UNeXt2, FullyConvolutionalMAE + _layers/ # Phase 6: DONE + __init__.py + conv_block_2d.py + conv_block_3d.py + unext2.py # Phase 7: UNeXt2 class ONLY (~50 lines) + fcmae.py # Phase 7: FCMAE + 10 FCMAE-specific items (~350 lines) +packages/viscy-models/tests/ + test_unet/ + __init__.py + test_layers.py # Phase 6: DONE (ConvBlock2D/3D) + test_unext2.py # Phase 7: NEW forward-pass tests + test_fcmae.py # Phase 7: MIGRATED from existing tests +``` + +### Pattern 1: UNeXt2 Migration (Thin Wrapper) +**What:** UNeXt2 is a composition layer that wires extracted components together.

UNeXt2 uses `encoder_stages`, FCMAE uses `encoder`. They are different models with different attribute names. +- **Extracting FCMAE-specific classes to _components:** `MaskedConvNeXtV2Block`, `MaskedConvNeXtV2Stage`, etc. are ONLY used by FCMAE. They do not belong in `_components/`. +- **Changing the `num_channels` mutation pattern:** In UNeXt2.__init__, `num_channels = multi_scale_encoder.feature_info.channels()` returns a list, and later `decoder_channels = num_channels; decoder_channels.reverse()` mutates it. This is the original behavior; do not "fix" this -- it would change the decoder_channels computation. +- **Re-exporting FCMAE internal classes from unet/__init__.py:** Only `FullyConvolutionalMAE` and `UNeXt2` should be in `__all__`. Internal FCMAE helper classes/functions are implementation details. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| ConvNeXtV2 encoder backbone | Custom encoder | `timm.create_model(backbone, features_only=True)` | Pretrained weights, multi-scale features, proven architecture | +| Masked depthwise convolution | Custom sparse conv | FCMAE's `MaskedConvNeXtV2Block` (from original code) | ConvNeXt V2 paper reference implementation | +| Pixel shuffle upsampling | Custom upsampler | `monai.networks.blocks.UpSample(mode="pixelshuffle")` | Handles padding, pre-conv, tested | +| Weight initialization | Manual init | `timm.models.convnext._init_weights` and `icnr_init` | ICNR prevents checkerboard artifacts | + +**Key insight:** Both UNeXt2 and FCMAE are composition layers over timm + monai primitives. The migration is import-path rewiring, not architecture work. + +## Common Pitfalls + +### Pitfall 1: num_channels List Mutation in UNeXt2.__init__ +**What goes wrong:** The original `UNeXt2.__init__` calls `multi_scale_encoder.feature_info.channels()` which returns a list `[96, 192, 384, 768]`. It then does `decoder_channels = num_channels` (aliasing, not copying), followed by `decoder_channels.reverse()` and `decoder_channels[-1] = ...`. This mutates the original list. +**Why it happens:** Python list aliasing. `decoder_channels` and `num_channels` are the same object. +**How to avoid:** Preserve this exact behavior during migration. Do NOT "fix" it by doing `decoder_channels = list(num_channels)` -- this could subtly change behavior if any downstream code references `num_channels` after the mutation. The original works because nothing reads `num_channels` after it is reversed. +**Warning signs:** If you change this pattern and see wrong decoder channel counts, this is why. + +### Pitfall 2: FCMAE Import Path Change +**What goes wrong:** Original FCMAE imports `from viscy.unet.networks.unext2 import PixelToVoxelHead, UNeXt2Decoder`. The migrated version must import from `viscy_models._components`. +**Why it happens:** Components were extracted to `_components/` in Phase 6. +**How to avoid:** Change exactly three import lines: + - `from viscy.unet.networks.unext2 import PixelToVoxelHead, UNeXt2Decoder` becomes two imports from `viscy_models._components.heads` and `viscy_models._components.blocks` + - `PixelToVoxelShuffleHead` is already defined in fcmae.py in the original, but was also extracted to `_components/heads.py` in Phase 6. Import it from `_components` instead of redefining it. +**Warning signs:** `ImportError` at import time. + +### Pitfall 3: PixelToVoxelShuffleHead Duplication +**What goes wrong:** In the original codebase, `PixelToVoxelShuffleHead` is defined in BOTH `unext2.py` and `fcmae.py`. Phase 6 extracted it to `_components/heads.py`. During FCMAE migration, you must import from `_components` and NOT copy the class definition again. +**Why it happens:** Historical code duplication in the original monolith. +**How to avoid:** Import `PixelToVoxelShuffleHead` from `viscy_models._components.heads` in fcmae.py. Verify the definition is identical (it is -- confirmed by source analysis). +**Warning signs:** Two definitions of the same class causing confusion or state dict mismatches. + +### Pitfall 4: FCMAE Test Import Updates +**What goes wrong:** All 11 existing FCMAE tests import from `viscy.unet.networks.fcmae`. These must be updated to `viscy_models.unet.fcmae`. +**Why it happens:** Standard migration import update. +**How to avoid:** Systematic find-and-replace of import paths in the migrated test file. Also note that `test_pixel_to_voxel_shuffle_head` tests a class that now lives in `_components.heads` -- update its import to come from the FCMAE module (since it is re-exported there) or from `_components.heads` directly. +**Warning signs:** `ModuleNotFoundError` when running tests. + +### Pitfall 5: UNeXt2 Test Memory +**What goes wrong:** UNeXt2 with `convnextv2_tiny` backbone on a 256x256x5 input creates ~273 state dict keys. Full forward-pass tests use significant memory. +**Why it happens:** ConvNeXtV2 tiny has ~28M parameters. +**How to avoid:** Use smaller spatial sizes (128x128 or 64x64) and smaller backbones (`convnextv2_atto` has 3.7M params, channels [40, 80, 160, 320]) for parametrized tests. Reserve one test with the default `convnextv2_tiny` for validation. Use `torch.no_grad()` in forward-pass tests. +**Warning signs:** OOM errors in CI, slow test execution. + +### Pitfall 6: FCMAE pretraining Flag Behavior +**What goes wrong:** FCMAE's `forward()` returns a tuple `(output, mask)` when `self.pretraining=True` (default) but just `output` when `False`. Tests must handle both return types. +**Why it happens:** Design decision for training vs inference modes. +**How to avoid:** Test both modes. When `pretraining=True`: expect `(Tensor, BoolTensor|None)`. When `pretraining=False`: expect `Tensor`. +**Warning signs:** Test assertions fail because of unpacking a non-tuple return. + +## Code Examples + +### UNeXt2 Complete Migration (verified working)

28.6M params). + - Recommendation: Use `convnextv2_atto` for parametrized tests (speed), one test with `convnextv2_tiny` for default config validation. All forward-pass tests should use `torch.no_grad()` to reduce memory. + +2. **Should `test_pixel_to_voxel_shuffle_head` stay in FCMAE tests?** + - What we know: Phase 6 already has this test in `test_components/test_heads.py` but with different parameters. + - Recommendation: Keep both. The FCMAE test uses `(240, 3, 5, 4)` params matching FCMAE usage; the component test uses `(160, 2, 5, 4)` params. Different coverage is valuable. + +3. **Should FCMAE tests import `PixelToVoxelShuffleHead` from `_components.heads` or `unet.fcmae`?** + - What we know: The class will be imported (not defined) in fcmae.py. It could be re-exported or not. + - Recommendation: Import from `viscy_models._components.heads` in the test since that is the canonical location. The FCMAE module should NOT re-export it in `__all__`. + +## Sources + +### Primary (HIGH confidence) +- **Local repo main branch** -- `viscy/unet/networks/unext2.py` (UNeXt2 source, ~290 lines) +- **Local repo main branch** -- `viscy/unet/networks/fcmae.py` (FCMAE source, ~370 lines) +- **Local repo main branch** -- `tests/unet/test_fcmae.py` (existing FCMAE tests, 11 test functions) +- **Local repo modular-models branch** -- Phase 6 extracted components (stems.py, heads.py, blocks.py) verified working +- **Runtime verification** -- UNeXt2 full forward pass tested with extracted components: `(1, 1, 5, 256, 256)` -> `(1, 2, 5, 256, 256)`, confirmed 2026-02-12 +- **Runtime verification** -- timm 1.0.24 API: `timm.create_model('convnextv2_tiny', features_only=True)`, ConvNeXtStage, all FCMAE timm imports verified +- **Runtime verification** -- State dict keys: 273 keys with prefixes `encoder_stages`, `stem`, `decoder`, `head` + +### Secondary (MEDIUM confidence) +- None needed -- all critical claims verified by direct source analysis and runtime testing. + +### Tertiary (LOW confidence) +- None. + +## Metadata + +**Confidence breakdown:** +- Standard stack: HIGH -- All dependencies verified from lockfile and runtime imports +- Architecture: HIGH -- Full UNeXt2 forward pass verified with extracted components; FCMAE dependencies confirmed available +- Pitfalls: HIGH -- State dict keys enumerated from runtime model instantiation; mutable defaults identified from source +- Test design: HIGH -- Existing FCMAE tests read from source; UNeXt2 test configs derived from verified forward passes + +**Research date:** 2026-02-12 +**Valid until:** 2026-03-12 (stable domain; timm/monai APIs verified at current versions) From f674982a90d59f41cb4f5fc2100b243da85beae4 Mon Sep 17 00:00:00 2001 From: Eduardo Hirata-Miyasaki Date: Thu, 12 Feb 2026 17:04:14 -0800 Subject: [PATCH 018/240] docs(07): create phase plan for core UNet models --- .planning/ROADMAP.md | 8 +- .../phases/07-core-unet-models/07-01-PLAN.md | 170 +++++++++++++++ .../phases/07-core-unet-models/07-02-PLAN.md | 206 ++++++++++++++++++ 3 files changed, 380 insertions(+), 4 deletions(-) create mode 100644 .planning/phases/07-core-unet-models/07-01-PLAN.md create mode 100644 .planning/phases/07-core-unet-models/07-02-PLAN.md diff --git a/.planning/ROADMAP.md b/.planning/ROADMAP.md index c5eb3c6f9..fa40a5198 100644 --- a/.planning/ROADMAP.md +++ b/.planning/ROADMAP.md @@ -84,11 +84,11 @@ Plans: 2. `from viscy_models.unet import FullyConvolutionalMAE` works and the model produces correct output shapes 3.

The source code lives at `viscy/representation/contrastive.py` (latest version at commit fe7a5da^, which includes both `projection_mlp()`, `ContrastiveEncoder`, and `ResNet3dEncoder` from PR #285) and `viscy/representation/vae.py` (same commit, containing `VaeUpStage`, `VaeEncoder`, `VaeDecoder`, `BetaVae25D`, and `BetaVaeMonai`). + +The contrastive models are straightforward wrappers: `ContrastiveEncoder` wraps a timm backbone (convnext_tiny/convnextv2_tiny/resnet50) with `StemDepthtoChannels` + a projection MLP, while `ResNet3dEncoder` wraps MONAI's `ResNetFeatures` with a projection MLP. The VAE models are more complex: `BetaVae25D` composes `VaeEncoder` (timm backbone with 3D-to-2D stem) and `VaeDecoder` (custom upsampling stages with `PixelToVoxelHead`), while `BetaVaeMonai` is a thin wrapper around MONAI's `VarAutoEncoder`. Per the Phase 6 research decision, `VaeUpStage`, `VaeEncoder`, and `VaeDecoder` stay in `vae/` module -- NOT in `_components/`. + +A critical finding during research: the `ContrastiveEncoder` code uses `encoder.head.fc.in_features` unconditionally for all backbones, but timm's ResNet models expose the classifier at `encoder.fc` (not `encoder.head.fc`). ConvNeXt models DO have `head.fc`. This means the `backbone="resnet50"` path has always been broken for `ContrastiveEncoder`. Since the original code has this bug and there are no existing checkpoints using this path (no tests ever existed), the migration should fix it by using timm's uniform API (`model.num_features` / `model.get_classifier()`). However, this fix must be carefully scoped to preserve state dict keys for the working convnext backbone paths. + +**Primary recommendation:** Split into two plans -- (1) contrastive models with `projection_mlp` utility, (2) VAE models with `VaeUpStage`/`VaeEncoder`/`VaeDecoder` helper classes.

Per Phase 6 decision, these helpers stay in the vae/ module, NOT in _components/. + +**Import changes:** +```python +# BEFORE (original): +from viscy.unet.networks.unext2 import PixelToVoxelHead, StemDepthtoChannels + +# AFTER (migrated): +from viscy_models._components.heads import PixelToVoxelHead +from viscy_models._components.stems import StemDepthtoChannels +``` + +**State dict keys preserved:** +- BetaVae25D: `self.encoder` (VaeEncoder), `self.decoder` (VaeDecoder) +- VaeEncoder: `self.stem`, `self.encoder`, `self.fc`, `self.fc_mu`, `self.fc_logvar` +- VaeDecoder: `self.latent_reshape`, `self.latent_proj`, `self.decoder_stages`, `self.head` +- VaeUpStage: `self.upsample`, `self.conv` + +### Pattern 4: VAE Model Migration (BetaVaeMonai) + +**What:** Migrate BetaVaeMonai to `vae/beta_vae_monai.py`. This is the simplest model -- a thin wrapper around MONAI's VarAutoEncoder. + +**Import changes:** None needed. BetaVaeMonai only imports from monai and torch (no viscy imports). + +**State dict keys preserved:** `self.model` (VarAutoEncoder) + +### Pattern 5: projection_mlp Placement + +**What:** The `projection_mlp()` function is used by both `ContrastiveEncoder` and `ResNet3dEncoder`. Per Phase 6 research recommendation, it stays in the contrastive module (NOT _components/) since it is only used by contrastive models. + +**Placement:** Define in `contrastive/encoder.py`, import in `contrastive/resnet3d.py`. + +```python +# contrastive/encoder.py +def projection_mlp(in_dims: int, hidden_dims: int, out_dims: int) -> nn.Module: + return nn.Sequential( + nn.Linear(in_dims, hidden_dims), + nn.BatchNorm1d(hidden_dims), + nn.ReLU(inplace=True), + nn.Linear(hidden_dims, out_dims), + nn.BatchNorm1d(out_dims), + ) + +# contrastive/resnet3d.py +from viscy_models.contrastive.encoder import projection_mlp +``` + +### Pattern 6: Mutable Default Fix (COMPAT-02) + +**What:** VaeDecoder has two mutable list defaults that must be converted to tuples. + +```python +# BEFORE (mutable defaults): +class VaeDecoder(nn.Module): + def __init__( + self, + decoder_channels: list[int] = [1024, 512, 256, 128], # MUTABLE + strides: list[int] = [2, 2, 2, 1], # MUTABLE + ): + +# AFTER (immutable defaults): +class VaeDecoder(nn.Module): + def __init__( + self, + decoder_channels: Sequence[int] = (1024, 512, 256, 128), # IMMUTABLE + strides: Sequence[int] = (2, 2, 2, 1), # IMMUTABLE + ): +``` + +**Note:** ContrastiveEncoder, ResNet3dEncoder, VaeEncoder, BetaVae25D, and BetaVaeMonai all use immutable defaults already (tuples or scalars). Only VaeDecoder needs fixing. + +### Anti-Patterns to Avoid + +- **Moving VaeUpStage/VaeEncoder/VaeDecoder to _components/:** Phase 6 research explicitly decided these stay in `vae/`. They are VAE-specific, not shared across model families. +- **Putting projection_mlp in _components/:** Only used by contrastive models. Not a shared component. +- **Using pretrained=True in tests:** Both timm and MONAI pretrained options download weights from the internet. Tests MUST use `pretrained=False` to avoid network calls and keep tests fast/deterministic. +- **Splitting VaeEncoder/VaeDecoder into separate files:** They are tightly coupled to BetaVae25D and should stay in `beta_vae_25d.py` as internal classes. +- **Changing module attribute names:** `self.stem`, `self.encoder`, `self.projection`, `self.decoder`, `self.model`, `self.head` etc. must remain exactly as-is. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| 2D ConvNeXt/ResNet backbone | Custom 2D encoder | `timm.create_model()` | Pretrained weights, state dict compatibility | +| 3D ResNet feature extractor | Custom 3D ResNet | `monai.networks.nets.resnet.ResNetFeatures` | MedicalNet pretrained weights, spatial_dims=3 support | +| Full VAE architecture | Custom encoder-decoder | `monai.networks.nets.VarAutoEncoder` | Handles latent space, reparameterization, encoder/decoder symmetry | +| 2D upsampling with residuals | Custom upsampling | `monai.networks.blocks.UpSample` + `monai.networks.blocks.ResidualUnit` | Edge cases handled, medical imaging validated | +| Transposed convolution layer | Custom deconv | `monai.networks.blocks.dynunet_block.get_conv_layer` | Handles normalization, padding, transposed convolutions correctly | +| Projection MLP | Custom classifier head | `projection_mlp()` from `contrastive/encoder.py` | Consistent architecture, shared between ContrastiveEncoder and ResNet3dEncoder | + +## Common Pitfalls + +### Pitfall 1: ContrastiveEncoder ResNet50 Backbone Bug + +**What goes wrong:** The original `ContrastiveEncoder` code accesses `encoder.head.fc.in_features` and `encoder.head.fc = nn.Identity()` unconditionally. For timm's ConvNeXt models, `head.fc` exists. For timm's ResNet models, the classifier is at `encoder.fc` -- there is NO `head` attribute. + +**Why it happens:** The original code was likely only tested with ConvNeXt backbones (the default). The ResNet50 path in `ContrastiveEncoder` was never exercised (no tests existed). + +**How to fix during migration:** Use timm's uniform API to handle both backbone families: +```python +# Instead of: encoder.head.fc.in_features +# Use: encoder.num_features (works for ALL timm models) +classifier_in_features = encoder.num_features + +# Instead of: encoder.head.fc = nn.Identity() +# Use: encoder.reset_classifier(0) or backbone-specific replacement +if "convnext" in backbone: + encoder.head.fc = nn.Identity() +elif "resnet" in backbone: + encoder.fc = nn.Identity() +``` + +**State dict impact:** For ConvNeXt backbones (the only ones with existing checkpoints), the state dict keys are unchanged. The `encoder.head.fc` replacement with `nn.Identity()` results in an `encoder.head.fc` key that stores nothing meaningful. For ResNet50, there are no existing checkpoints to worry about. + +**Confidence:** HIGH -- Verified by creating both model types and inspecting `named_children()` output. + +### Pitfall 2: ResNet3dEncoder embedding_dim Mismatch + +**What goes wrong:** `ResNet3dEncoder(backbone="resnet50", embedding_dim=512)` creates a projection MLP with `in_dims=512`, but ResNet-50's last feature has 2048 channels. The `projection_mlp(512, 512, 128)` would receive 2048-dim input, causing a shape mismatch at runtime. + +**Why it happens:** The `embedding_dim` parameter defaults to 512, which matches ResNet-10/18 but NOT ResNet-50/101/152. + +**How to avoid:** Document the correct embedding_dim values. Tests should use matching values: +- ResNet-10, ResNet-18, ResNet-34: `embedding_dim=512` +- ResNet-50, ResNet-101, ResNet-152, ResNet-200: `embedding_dim=2048` + +**Warning signs:** `RuntimeError: mat1 and mat2 shapes cannot be multiplied` during forward pass. + +**Confidence:** HIGH -- Verified by running `ResNetFeatures` with different backbones and checking output dims. + +### Pitfall 3: BatchNorm1d with Batch Size 1 + +**What goes wrong:** `projection_mlp()` uses `nn.BatchNorm1d` which requires batch_size > 1 during training (eval mode works with batch_size=1). + +**Why it happens:** BatchNorm computes mean/variance across the batch dimension. With batch_size=1, there is only one sample so variance is undefined. + +**How to avoid:** Tests MUST either use batch_size >= 2 OR call `model.eval()` before the forward pass. Using both is safest. + +**Warning signs:** `ValueError: Expected more than 1 value per channel when training` + +**Confidence:** HIGH -- Directly encountered this error during MONAI ResNetFeatures testing. + +### Pitfall 4: SimpleNamespace Return Type + +**What goes wrong:** `BetaVae25D.forward()` and `BetaVaeMonai.forward()` return `SimpleNamespace` objects, not tensors or named tuples. This breaks TorchScript/ONNX export. + +**Why it happens:** Original design choice for flexible attribute access. + +**How to avoid:** Accept this as a known limitation. Do NOT change the return type during migration -- it would break all downstream code. Document in tests that output is `SimpleNamespace`. + +**Scope note:** ONNX/TorchScript export is explicitly out of scope per REQUIREMENTS.md. + +**Confidence:** HIGH -- Verified from source code. + +### Pitfall 5: VaeEncoder ResNet50 Feature Count + +**What goes wrong:** ResNet50 in `features_only=True` mode returns 5 feature levels (channels=[64, 256, 512, 1024, 2048]) while ConvNeXt returns 4 (channels=[96, 192, 384, 768]). The `backbone_reduction = 2^(len(num_channels)-1)` formula gives different results: 16 for ResNet50, 8 for ConvNeXt. + +**Why it matters:** The VaeEncoder calculates `encoder_spatial_size` used by VaeDecoder. If this is wrong, the decoder produces wrong spatial dimensions. + +**Verification:** Tested that with `conv1 = Identity()`, ResNet50's effective reduction from stem output to last feature IS 16x (`2^4`), matching the formula. The code is correct. + +**Confidence:** HIGH -- Verified by running actual forward passes. + +### Pitfall 6: VaeDecoder Strides Has Extra Element + +**What goes wrong:** `BetaVae25D.__init__` creates `strides = [2] * decoder_stages + [1]`, which has `decoder_stages + 1` elements. But `VaeDecoder` iterates `len(decoder_channels) - 1` stages, using `strides[:len(decoder_channels)-1]`. The last stride `[1]` in the strides list is NOT used by any VaeUpStage. + +**Why it matters:** During testing, if someone passes mismatched strides/decoder_channels, the extra stride element is silently ignored. + +**How to avoid:** Preserve the original behavior exactly. Do not "fix" the strides list length. + +**Confidence:** HIGH -- Verified from source code analysis. + +### Pitfall 7: Test Input Size Constraints for BetaVae25D + +**What goes wrong:** BetaVae25D requires specific spatial sizes that are divisible by the stem stride AND the backbone reduction factor. For ResNet50 with `stem_stride=(2,4,4)` and `input_spatial_size=(256,256)`, the final spatial size is 2x2. Using smaller inputs like `(64,64)` would give 1x1, which causes issues with the latent space calculation. + +**Why it happens:** `spatial_channels = latent_dim // (spatial_size * spatial_size)`. If spatial_size=1, spatial_channels=latent_dim. If spatial_size=2, spatial_channels=latent_dim/4. + +**How to avoid:** Use input sizes that produce reasonable final spatial sizes. For tests: `input_spatial_size=(128, 128)` with `stem_stride=(2, 4, 4)` gives final spatial 2x2 for ResNet50, which works. Use `latent_dim` values divisible by `spatial_size^2`. + +**Test recommendation:** Use smaller latent_dim (e.g., 64 or 256) and smaller input (e.g., 128x128) to keep tests fast while maintaining correctness. + +**Confidence:** HIGH -- Verified by manual calculation and forward pass simulation. + +## Code Examples + +### ContrastiveEncoder Migration (contrastive/encoder.py) + +Source: `viscy/representation/contrastive.py` at commit fe7a5da^ (pre-monorepo) + +```python +"""Contrastive encoder using timm backbones with 3D-to-2D stem.""" + +from typing import Literal + +import timm +import torch.nn as nn +from torch import Tensor + +from viscy_models._components.stems import StemDepthtoChannels + + +def projection_mlp(in_dims: int, hidden_dims: int, out_dims: int) -> nn.Module: + """MLP projection head for contrastive learning.""" + return nn.Sequential( + nn.Linear(in_dims, hidden_dims), + nn.BatchNorm1d(hidden_dims), + nn.ReLU(inplace=True), + nn.Linear(hidden_dims, out_dims), + nn.BatchNorm1d(out_dims), + ) + + +class ContrastiveEncoder(nn.Module): + def __init__( + self, + backbone: Literal["convnext_tiny", "convnextv2_tiny", "resnet50"], + in_channels: int, + in_stack_depth: int, + stem_kernel_size: tuple[int, int, int] = (5, 4, 4), + stem_stride: tuple[int, int, int] = (5, 4, 4), + embedding_dim: int = 768, + projection_dim: int = 128, + drop_path_rate: float = 0.0, + ) -> None: + super().__init__() + self.backbone = backbone + encoder = timm.create_model( + backbone, + pretrained=False, #

For the viscy-models migration, the decision is: +- `ContrastiveEncoder`: Change default to `pretrained=False`. The original code downloads ImageNet weights during construction, which is a side effect. Users can pass `pretrained=True` when they want it. +- `ResNet3dEncoder`: Change default to `pretrained=False`. The original code downloads MedicalNet weights. Same reasoning. +- `VaeEncoder`: Already has `pretrained` as an explicit parameter (default `True`). Change to default `False` for consistency. + +**IMPORTANT:** This changes the constructor signature default, but NOT the behavior when explicitly passed. All LightningModule wrappers in applications/ explicitly set `pretrained=True/False`, so changing the default does not break downstream usage. + +**Alternative:** Keep `pretrained=True` as default to match original behavior exactly. The downside is that constructing a model always triggers a network download. + +**Recommendation:** Change to `pretrained=False` for clean nn.Module semantics. Document in code comments. + +## Open Questions + +1. **Should ContrastiveEncoder pretrained default change to False?** + - What we know: Original uses `pretrained=True`. viscy-models aims for pure nn.Module without side effects. Phase 7's UNeXt2 already uses `pretrained=False` as default. + - What's unclear: Whether downstream code relies on the default `True`. + - Recommendation: Change to `pretrained=False` for consistency with UNeXt2 pattern. This is a cosmetic change since application-level code always passes the argument explicitly. + +2. **Should the ResNet50 ContrastiveEncoder bug be fixed or preserved?** + - What we know: `encoder.head.fc` does not exist for timm ResNet models. ConvNeXt path works. No checkpoints exist for the ResNet50 path. + - What's unclear: Whether someone has a workaround in their training scripts. + - Recommendation: Fix it. The code never worked for ResNet50 -- there is nothing to break. Use `encoder.num_features` for the projection input dim and backbone-specific classifier reset. + +3. **Test input sizes for BetaVae25D** + - What we know: Full-size inputs (256x256, 16 Z-slices) with ResNet50 backbone create large models.

These are simpler architectures than UNeXt2/FCMAE -- they do NOT use timm backbones or shared `_components/` modules. Instead they compose ConvBlock2D and ConvBlock3D (already migrated to `unet/_layers/` in Phase 6) with standard PyTorch pooling and upsampling layers. The migration is primarily a copy-and-update-imports exercise, with careful attention to the `register_modules`/`add_module` pattern that governs state dict keys. + +The original tests are written in unittest style with a combinatorial explosion approach -- each test class runs all 144 parameter configurations via Cartesian product. They also depend on `viscy.utils.cli_utils.show_progress_bar`, a utility not available in viscy-models. The tests have a known shape mismatch: the `squeeze(2)`/`unsqueeze(2)` was added to Unet2D's forward method in commit `0e2b575` after the tests were written, and the test expected shapes were never updated. The test conversion must fix this mismatch, remove the cli_utils dependency, and convert from unittest to idiomatic pytest using `@pytest.mark.parametrize` for configuration coverage. + +Both models use `num_filters=[]` (mutable list default) which must be converted to `num_filters=()` per COMPAT-02. The `up_list` in both models is a plain Python list (not registered via `register_modules`) because `nn.Upsample` has no learnable parameters -- this is fine and must be preserved as-is. + +**Primary recommendation:** Copy Unet2d and Unet25d verbatim from v0.3.3, update imports to `viscy_models.unet._layers`, fix `num_filters` mutable default, and write new pytest tests that verify correct output shapes (accounting for squeeze/unsqueeze), state dict key patterns, and a representative subset of parameter configurations. + +## Standard Stack + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| torch | >=2.10 | nn.Module base, Conv2d/3d, AvgPool, Upsample | All model components are pure PyTorch | +| numpy | >=2.4.1 | `np.linspace` in ConvBlock2D/3D filter step calculation | Indirect dependency via ConvBlock layers | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| pytest | >=9.0.2 | Test framework | pytest.mark.parametrize for config combos | + +### Not Needed (Unlike Other Phases) +| Library | Not Needed Because | +|---------|-------------------| +| timm | Unet2d/Unet25d do not use pretrained backbones | +| monai | Unet2d/Unet25d do not use MONAI blocks | +| viscy.utils.cli_utils | Test dependency on `show_progress_bar` must be removed | + +**Installation:** +```bash +uv sync --package viscy-models # Already configured from Phase 6 +``` + +## Architecture Patterns + +### File Placement +``` +packages/viscy-models/ + src/viscy_models/ + unet/ + __init__.py # Add Unet2d, Unet25d to exports + _layers/ + conv_block_2d.py # Already exists (Phase 6) + conv_block_3d.py # Already exists (Phase 6) + unet2d.py # NEW: Unet2d class + unet25d.py # NEW: Unet25d class + tests/ + test_unet/ + test_unet2d.py # NEW: pytest tests for Unet2d + test_unet25d.py # NEW: pytest tests for Unet25d +``` + +### Pattern 1: Import Path Update (Only Change to Model Code) +**What:** Update the import of ConvBlock2D/ConvBlock3D from old monolithic path to new package path. +**When to use:** Every model file migration. + +```python +# BEFORE (v0.3.3 source): +from viscy.unet.networks.layers.ConvBlock2D import ConvBlock2D + +# AFTER (viscy-models): +from viscy_models.unet._layers.conv_block_2d import ConvBlock2D +``` + +### Pattern 2: Mutable Default Fix +**What:** Replace `num_filters=[]` with `num_filters=()` in both Unet2d and Unet25d constructors. +**When to use:** Both model classes. + +```python +# BEFORE: +def __init__(self, ..., num_filters=[], ...): + if len(num_filters) != 0: + ... + else: + self.num_filters = [pow(2, i) * 16 for i in range(num_blocks + 1)] + +# AFTER: +def __init__(self, ..., num_filters=(), ...): + if len(num_filters) != 0: + ... + else: + self.num_filters = [pow(2, i) * 16 for i in range(num_blocks + 1)] +``` + +The internal code continues to work because `len(())` is 0, and `len(some_tuple)` returns the correct length for non-empty tuples too. + +### Pattern 3: register_modules / add_module (Preserve Verbatim) +**What:** Both Unet2d and Unet25d define their own `register_modules()` method that calls `self.add_module()`. This creates state dict keys like `down_samp_0`, `down_conv_block_0`, `up_conv_block_0`, etc. +**Why critical:** These exact key names must be preserved for checkpoint compatibility. +**Do NOT refactor to nn.ModuleList.** + +```python +# This pattern MUST be preserved exactly: +def register_modules(self, module_list, name): + for i, module in enumerate(module_list): + self.add_module(f"{name}_{str(i)}", module) +``` + +### Pattern 4: unet/__init__.py Export Update +**What:** Add Unet2d and Unet25d to the unet subpackage exports. + +```python +# packages/viscy-models/src/viscy_models/unet/__init__.py +"""UNet family architectures.""" + +from viscy_models.unet.fcmae import FullyConvolutionalMAE +from viscy_models.unet.unet2d import Unet2d +from viscy_models.unet.unet25d import Unet25d +from viscy_models.unet.unext2 import UNeXt2 + +__all__ = ["UNeXt2", "FullyConvolutionalMAE", "Unet2d", "Unet25d"] +``` + +### Anti-Patterns to Avoid +- **Refactoring register_modules to nn.ModuleList:** Changes state dict keys from `down_conv_block_0.*` to `down_conv_blocks.0.*`. Breaks checkpoint loading. +- **Removing the up_list as plain Python list:** nn.Upsample has no parameters. Registering it would add useless entries to state dict. Keep as-is. +- **Removing the squeeze(2)/unsqueeze(2) from Unet2d:** This was added intentionally (commit `0e2b575`) to normalize the 2D model to accept 5D input (BCZYX) matching the 2.5D/3D models. +- **Running the full 144-configuration Cartesian product in pytest:** This creates 432+ slow tests.

This makes the migration simpler. + +## Common Pitfalls + +### Pitfall 1: Unet2d Test Shape Mismatch (Known Bug in Original Tests) +**What goes wrong:** Original test expected shapes assume 4D output `(B, C, H, W)` but after commit `0e2b575`, Unet2d returns 5D `(B, C, 1, H, W)` due to `unsqueeze(2)`. +**Why it happens:** The `squeeze(2)/unsqueeze(2)` normalization was added after the tests were written, and the test expected shapes were never updated. +**How to avoid:** Write new pytest tests with correct 5D expected shapes: `(B, C, 1, H, W)` for 4D input (Z=1 gets squeezed then unsqueezed) and `(B, C, 1, H, W)` for 5D input with Z=1 squeezed dimension. +**Verification:** +```python +# 4D input: (1, 1, 256, 256) -> squeeze(2) does nothing (dim 2 = 256, not 1) +# -> conv processing -> unsqueeze(2) -> (1, 1, 1, 256, 256) +# 5D input: (1, 1, 1, 256, 256) -> squeeze(2) -> (1, 1, 256, 256) +# -> conv processing -> unsqueeze(2) -> (1, 1, 1, 256, 256) +``` + +### Pitfall 2: Original Test Dependency on viscy.utils.cli_utils +**What goes wrong:** Original tests import `viscy.utils.cli_utils.show_progress_bar` which does not exist in viscy-models. +**Why it happens:** Legacy test utility for progress bars during exhaustive configuration testing. +**How to avoid:** Do not port the cli_utils dependency. Write new pytest-native tests that do not need progress bar utilities. + +### Pitfall 3: Cartesian Product Test Explosion +**What goes wrong:** Original tests run 144 configurations x 3 tests = 432 forward passes per model, taking several minutes. +**Why it happens:** Exhaustive testing via `itertools.product` of all parameter combinations. +**How to avoid:** Use `@pytest.mark.parametrize` with a representative subset that covers the important axes of variation: +- `num_blocks`: 1 (minimum), 4 (standard) +- `residual`: True, False +- `task`: "reg", "seg" +- `kernel_size`: (3, 3) (standard) +- `dropout`: 0.0 (off), 0.25 (on) +- Multi-channel I/O (single test) + +This gives ~8-12 well-chosen test cases instead of 144, covering all meaningful code paths. + +### Pitfall 4: Unet25d skip_conv_layers Dimension Coupling +**What goes wrong:** The `skip_conv_layers` in Unet25d use `kernel_size=(1 + in_stack_depth - out_stack_depth, 1, 1)`, tightly coupling the Z-compression to the depth parameters. Using wrong depth values produces dimension errors. +**Why it happens:** The 2.5D architecture intentionally compresses Z in both the bottom transition and skip connections. +**How to avoid:** Tests must verify the standard case (in=5, out=1) and at least one case where in_depth equals out_depth (kernel_z=1, Z preserved). + +### Pitfall 5: State Dict Key Patterns Differ Between Unet2d and Unet25d +**What goes wrong:** Assuming both models have identical state dict structure. +**Why it happens:** Similar architecture but key differences: +- Unet2d: Uses `ConvBlock2D`, `nn.AvgPool2d`, `nn.Upsample(mode='bilinear')`. No skip conv layers. +- Unet25d: Uses `ConvBlock3D`, `nn.AvgPool3d`, `nn.Upsample(mode='trilinear')`, and has additional `skip_conv_layer_N` modules. +**How to avoid:** Test state dict key prefixes independently for each model. Unet25d should have `skip_conv_layer_0`, Unet2d should not. + +### Pitfall 6: ConvBlock2D Dropout Registration Asymmetry +**What goes wrong:** Tests pass with dropout=0 but fail with dropout>0 because of a subtle difference. +**Why it happens:** ConvBlock2D does NOT register dropout modules via `register_modules` (just stores them in `self.drop_list`), while ConvBlock3D DOES register them. This means ConvBlock2D dropout won't be in the state dict. This is the original behavior and must be preserved. +**How to avoid:** Don't test for dropout module registration in Unet2d state dict. Only test it for Unet25d (which uses ConvBlock3D that does register dropout). + +## Code Examples + +### Unet2d Migration (Complete) +```python +# packages/viscy-models/src/viscy_models/unet/unet2d.py +"""2D UNet with variable depth and configurable convolutional blocks.""" + +import torch +import torch.nn as nn + +from viscy_models.unet._layers.conv_block_2d import ConvBlock2D + +__all__ = ["Unet2d"] + + +class Unet2d(nn.Module): + # ... copy verbatim from v0.3.3 ... + # ONLY changes: + # 1.

Input `(1, 1, 1, 64, 64)`, verify output shape `(1, 1, 1, 64, 64)`. + + 3. `test_unet2d_multichannel`: `in_channels=2, out_channels=3`, verify output channel dimension is 3. + + 4. `test_unet2d_residual`: `@pytest.mark.parametrize("residual", [True, False])`. Verify both modes produce same output shape. Optionally verify parameter count is identical (residual mode in ConvBlock2D uses addition, not extra params). + + 5. `test_unet2d_task_mode`: `@pytest.mark.parametrize("task", ["reg", "seg"])`. Verify both modes produce valid output shapes. (reg uses linear activation, seg uses relu in terminal block.) + + 6. `test_unet2d_dropout`: `dropout=0.25`. Verify forward pass succeeds (dropout active during training, no state dict impact for ConvBlock2D). + + 7. `test_unet2d_state_dict_keys`: `num_blocks=2`. Verify state dict key prefixes: `down_conv_block_0`, `down_conv_block_1`, `bottom_transition_block`, `up_conv_block_0`, `up_conv_block_1`, `terminal_block`. Verify `down_samp` is NOT in state dict (AvgPool2d has no params). + + 8. `test_unet2d_custom_num_filters`: `num_filters=(32, 64, 128)` with `num_blocks=2`. Verify forward pass succeeds with custom filter sizes. + + **test_unet25d.py** -- approximately 8-10 test cases: + + 1. `test_unet25d_default_forward`: `in_stack_depth=5, out_stack_depth=1`, input `(1, 1, 5, 64, 64)`, verify output `(1, 1, 1, 64, 64)`. This is the standard Z-compression case. + + 2. `test_unet25d_preserved_depth`: `in_stack_depth=5, out_stack_depth=5`, verify output Z matches input Z. This tests the `kernel_size=(1, 1, 1)` skip path. + + 3. `test_unet25d_variable_depth`: `@pytest.mark.parametrize("num_blocks", [1, 2, 4])`. Verify different encoder/decoder depths work. + + 4. `test_unet25d_multichannel`: `in_channels=2, out_channels=3`, verify output channel dimension. + + 5. `test_unet25d_residual`: `@pytest.mark.parametrize("residual", [True, False])`. Verify both modes produce valid output shapes. + + 6. `test_unet25d_task_mode`: `@pytest.mark.parametrize("task", ["reg", "seg"])`. Verify both task modes. + + 7. `test_unet25d_state_dict_keys`: `num_blocks=2`. Verify: `down_conv_block_0`, `down_conv_block_1`, `bottom_transition_block`, `up_conv_block_0`, `up_conv_block_1`, `terminal_block`, `skip_conv_layer_0`, `skip_conv_layer_1`. Verify `down_samp` NOT in state dict. + + 8. `test_unet25d_custom_num_filters`: `num_filters=(32, 64, 128)` with `num_blocks=2`. Verify forward pass with custom filters. + + All tests use `torch.no_grad()` for forward passes. Use the `device` fixture from conftest.py if available, otherwise CPU-only is fine (these are pure conv models, no GPU-specific behavior). + + Use small spatial dimensions (64x64) and `num_blocks <= 2` for speed in parametrized tests. Only use 256x256 for the single default forward test (num_blocks=4 needs enough spatial resolution for 4 pooling stages). + + + Run `uv run --package viscy-models pytest packages/viscy-models/tests/test_unet/test_unet2d.py packages/viscy-models/tests/test_unet/test_unet25d.py -v --tb=short` to verify all new tests pass. + Run `uv run --package viscy-models pytest packages/viscy-models/tests/ --tb=short -q` to verify full suite (existing 46 + new tests) passes with no regressions. + Run `uv run --package viscy-models ruff check packages/viscy-models/tests/test_unet/test_unet2d.py packages/viscy-models/tests/test_unet/test_unet25d.py` to confirm no lint errors. + + + All new Unet2d tests pass covering: default forward, variable depth, multichannel, residual, task mode, dropout, state dict keys, and custom filters. All new Unet25d tests pass covering: default forward with Z-compression, preserved depth, variable depth, multichannel, residual, task mode, state dict keys with skip_conv_layer verification, and custom filters.

Asserts equality against a frozen reference list + +Use these configurations for fast tests (avoid large backbones): +- `UNeXt2(backbone="convnextv2_atto")` -- smallest ConvNeXt backbone +- `FullyConvolutionalMAE(backbone="convnextv2_atto")` -- smallest ConvNeXt backbone +- `ContrastiveEncoder(backbone="convnext_tiny", in_channels=1, in_stack_depth=5, stem_kernel_size=(5, 4, 4))` -- convnext_tiny is the default +- `ResNet3dEncoder(in_channels=1)` -- uses MONAI ResNet, no timm +- `BetaVae25D(in_channels=1, out_channels=1, input_shape=(5, 64, 64))` -- minimal config. Uses default backbone="resnet50" +- `BetaVaeMonai(in_channels=1, out_channels=1, latent_dim=128, spatial_dims=2, input_shape=(64, 64))` -- 2D variant, smaller +- `Unet2d(in_channels=1, out_channels=1)` -- default config +- `Unet25d(in_channels=1, out_channels=1)` -- default config + +To generate the reference key sets: first write the tests WITH the model instantiation and a temporary `print(sorted(model.state_dict().keys()))` to capture the actual keys. Then freeze those as the reference. Or more practically: instantiate each model, capture keys, and assert they match a known reference. + +Since the reference keys are the current (correct) state and this is a regression test, the approach is: +1. Instantiate model +2. Get keys +3. Check specific structural properties that would break if state dict changed: + - Total number of keys (catches added/removed parameters) + - Presence of critical top-level prefixes (e.g., "stem.", "decoder.", "encoder.", "head.") + - A sample of specific key names from different parts of the model + +For each model, assert: +- `len(state_dict)` equals expected count +- A set of "sentinel keys" (5-10 keys from different parts of the model hierarchy) are all present +- No unexpected top-level prefixes appear + +This approach is more maintainable than freezing thousands of keys while still catching structural regressions. + +Use the `device` fixture from conftest.py. All models should be instantiated on CPU (no `.to(device)` needed since we only check keys, not forward pass). + +Add docstring: "State dict key compatibility tests ensuring migrated models preserve checkpoint-loadable structure." + +Import all models from top-level: `from viscy_models import UNeXt2, ...` (also tests Task 1). + + +Run `cd /Users/eduardo.hirata/Documents/repos/VisCy/packages/viscy-models && uv run --package viscy-models pytest tests/test_state_dict_compat.py -v`. All 8 tests should pass. + + State dict compatibility regression tests exist for all 8 models, verifying parameter count and sentinel key presence. Tests pass and would catch any structural changes that break checkpoint loading. + + + + Task 3: Add viscy-models to CI test matrix + .github/workflows/test.yml + +Update `.github/workflows/test.yml` to run viscy-models tests alongside viscy-transforms tests. + +The current workflow has a single `test` job that runs viscy-transforms only. Refactor to use a matrix strategy that tests both packages. + +Add a `package` dimension to the matrix: +```yaml +matrix: + os: [ubuntu-latest, macos-latest, windows-latest] + python-version: ["3.11", "3.12", "3.13"] + package: [viscy-transforms, viscy-models] +``` + +Update the job name to include the package: +```yaml +name: Test (${{ matrix.package }}, Python ${{ matrix.python-version }}, ${{ matrix.os }}) +``` + +Update the `Install dependencies` step to use `matrix.package`: +```yaml +- name: Install dependencies + run: uv sync --frozen --all-extras --dev + working-directory: packages/${{ matrix.package }} +``` + +Update the `Run tests with coverage` step to dynamically determine the coverage source. The import name differs from the package name (viscy-transforms -> viscy_transforms, viscy-models -> viscy_models). Use shell substitution to convert the hyphen: +```yaml +- name: Run tests with coverage + run: | + COV_PKG=$(echo "${{ matrix.package }}" | tr '-' '_') + uv run --frozen pytest --cov=$COV_PKG --cov-report=term-missing + working-directory: packages/${{ matrix.package }} +``` + +Note: On Windows, the `tr` command may not be available. Use a different approach that works cross-platform. Instead, use an `env` variable or matrix include. The simplest cross-platform approach: add a `cov-package` to the matrix via `include` or just use the package name directly since pytest-cov can accept the package directory path. + +Actually, the simplest cross-platform approach: use `--cov=src/` instead of a named package. This avoids the hyphen-to-underscore issue entirely and works on all platforms: +```yaml +- name: Run tests with coverage + run: uv run --frozen pytest --cov=src/ --cov-report=term-missing + working-directory: packages/${{ matrix.package }} +``` + +This works because both packages use the `src/` layout and `--cov=src/` will measure coverage for whatever is under `src/`. + +The `check` job already aggregates all test jobs via `alls-green`, so it will automatically include the new viscy-models test jobs. No changes needed to the `check` job. + +The total matrix will be 3 OS x 3 Python x 2 packages = 18 jobs (up from 9). + + +Validate the YAML syntax: `python -c "import yaml; yaml.safe_load(open('.github/workflows/test.yml'))"` (or just verify the file is valid YAML). Also visually inspect the matrix dimensions are correct. + +Note: The actual CI will run on push/PR to main. For local verification, just confirm the YAML is syntactically valid and the matrix is correctly structured. + + CI test workflow includes viscy-models in the test matrix alongside viscy-transforms. Matrix produces 18 jobs (3 OS x 3 Python x 2 packages). The `check` gate job automatically aggregates all test results. + + + + + +1.

If viscy-transforms needs `numpy<2` and a future package needs `numpy>=2`, resolution fails. - -**Why it happens:** uv workspaces assume all packages can coexist in one environment. This is by design for consistency but breaks when packages have incompatible dependency trees. - -**Consequences:** -- Cannot lock the workspace -- Must either downgrade the newer package's requirements or remove the conflicting package from the workspace - -**Prevention:** -- Survey dependency constraints before adding packages to workspace -- For PyTorch/NumPy heavy scientific packages, pin compatible version ranges early -- Use `[tool.uv.conflicts]` to declare mutually exclusive extras/groups if needed -- Consider path dependencies instead of workspace membership for packages with known conflicts +### Pitfall 1: Lazy Import Guard Ordering Breaks at Runtime, Not Import Time -**Detection:** `uv lock` fails with dependency resolution errors. +**What goes wrong:** +Optional dependencies (tensorstore, tensordict, pycocotools) are guarded with lazy imports like `try: import tensorstore` in module-level code. But if the guard is at the module level and the import is used inside a class method, the error only surfaces when that specific code path is exercised -- potentially deep inside a training loop after hours of preprocessing. Worse: if you guard the import at module level with a sentinel (`HAS_TENSORSTORE = False`) but forget to check the sentinel before using the library in a method, you get `NameError: name 'tensorstore' is not defined` instead of a helpful message. -**Phase:** Address during each package extraction (ongoing vigilance). - -**Confidence:** HIGH (verified in [uv resolution docs](https://docs.astral.sh/uv/concepts/resolution/)) +**Why it happens:** +During extraction, developers convert `import tensorstore` to a guarded import but don't systematically audit every usage site. The module has 13 files; it's easy to miss a call site in a nested helper. The triplet.py module in particular uses tensorstore inside a dataset `__getitem__` which is called by DataLoader workers -- the error appears in a worker subprocess stack trace, obscuring the real cause. + +**How to avoid:** +1. Use a centralized lazy import pattern in `_imports.py`: + ```python + def _require_tensorstore(): + try: + import tensorstore + return tensorstore + except ImportError: + raise ImportError( + "tensorstore is required for TripletDataModule. " + "Install it with: pip install viscy-data[triplet]" + ) from None + ``` +2. Call `_require_tensorstore()` at the top of every method that uses it, not at module level. +3. Add a test for each optional-dep module that verifies the ImportError message when the dep is missing. Use `pytest.importorskip` in tests, but also test the error path. +4. In CI, run one test job with only base deps installed (no extras) to catch unguarded imports. + +**Warning signs:** +- Any `import X` at module top-level for an optional dependency +- Tests that always install `[all]` extras -- they never catch missing-dep errors +- `NameError` in DataLoader worker processes during training + +**Phase to address:** +Package scaffolding phase (pyproject.toml + `_imports.py` helper). Verify in CI phase with a "minimal deps" test job. --- -### Pitfall 3: uv-dynamic-versioning Does Not Work with uv Build Backend - -**What goes wrong:** If you configure `build-backend = "uv"` instead of `build-backend = "hatchling.build"`, uv-dynamic-versioning silently fails or produces incorrect versions. - -**Why it happens:** uv-dynamic-versioning is a hatchling plugin. It requires hatchling as the build backend to function. - -**Consequences:** -- Packages built with version `0.0.0` or missing version -- CI releases fail -- PyPI uploads rejected or have wrong version - -**Prevention:** -- Always use `build-backend = "hatchling.build"` when using uv-dynamic-versioning -- Never use `build-backend = "uv"` or `build-backend = "uv_build"` with this plugin -- Verify version in built wheel/sdist before publishing - -**Detection:** Run `uv build` and check the generated filename for correct version. +### Pitfall 2: Manager().dict() Shared Cache Is Not Picklable Across spawn Contexts -**Phase:** Address in Phase 1 (build system setup). +**What goes wrong:** +`CachedOmeZarrDataset` uses `multiprocessing.Manager().dict()` as a shared cache across DataLoader workers. This works with PyTorch's default `fork` start method on Linux, but fails on macOS (default `spawn`) and Windows (only `spawn`). The `Manager` proxy objects must be passed to workers via pickling, and depending on when the Manager is created relative to DataLoader fork/spawn, you get either: (a) `RuntimeError: cannot pickle 'weakref' object` or (b) a silently separate cache per worker (defeating the purpose). -**Confidence:** HIGH (verified in [uv-dynamic-versioning README](https://github.com/ninoseki/uv-dynamic-versioning)) +**Why it happens:** +The original code was developed and tested on Linux HPC clusters where `fork` is the default. The extraction needs cross-platform CI (Ubuntu, macOS, Windows per existing test.yml matrix). The `spawn` start method creates fresh Python processes that must pickle everything passed to them. `Manager().dict()` proxy objects work across `fork` boundaries but behave differently under `spawn`. + +**How to avoid:** +1. Create the `Manager` in `setup()` (Lightning hook), not in `__init__`. Lightning's `setup()` runs after the Trainer has configured the multiprocessing context. +2. Store the manager reference on `self` so it persists for the lifetime of the DataModule. +3. Test with `mp_start_method="spawn"` explicitly in at least one CI configuration: + ```python + @pytest.fixture + def spawn_trainer(): + return Trainer(accelerator="cpu", devices=1, + strategy=SingleDeviceStrategy(device="cpu")) + ``` +4. Consider replacing `Manager().dict()` with `torch.multiprocessing.Queue` or a file-based cache (memory-mapped array via tensordict's `MemoryMappedTensor`) which is already used in `mmap_cache.py`. +5. Document that `num_workers=0` avoids the issue entirely (useful for debugging). + +**Warning signs:** +- Tests pass on Linux but fail on macOS/Windows CI +- `pickle` or `weakref` errors in DataLoader worker stack traces +- Cache hit rate is 0% despite repeated access to same volumes + +**Phase to address:** +Code migration phase. Must be addressed before CI matrix runs on macOS/Windows. --- -### Pitfall 4: Import Leakage Between Workspace Members - -**What goes wrong:** Python has no dependency isolation. viscy-transforms can accidentally import from viscy-data even if it doesn't declare that dependency, because all workspace members are installed in the same environment. - -**Why it happens:** `uv sync` installs all workspace members as editable. They share a virtual environment. Python doesn't enforce import boundaries. - -**Consequences:** -- Package works in monorepo but fails when installed standalone -- CI passes but users report `ModuleNotFoundError` -- Hidden coupling between packages - -**Prevention:** -- Run `uv sync --package viscy-transforms` and test in isolation -- CI should test each package independently, not just the whole workspace -- Consider running `uv pip install viscy-transforms --no-deps` and verifying imports work with only declared dependencies - -**Detection:** Install package in fresh venv outside workspace and run tests. - -**Phase:** Address in Phase 1 (CI setup) and validate with each extraction. +### Pitfall 3: Base Class Extraction Creates Hidden Import Cycles -**Confidence:** HIGH (explicitly documented in [uv workspaces docs](https://docs.astral.sh/uv/concepts/projects/workspaces/)) +**What goes wrong:** +`HCSDataModule` is both a concrete DataModule (used directly for translation fine-tuning) and the base class for `TripletDataModule` and `CellDivisionTripletDataModule`. It contains shared utility methods like `_read_norm_meta()` and references to iohub types. When extracting shared utilities into `_utils.py`, developers often create circular imports: `hcs.py` imports from `_utils.py`, but `_utils.py` needs types defined in `_typing.py` which imports from something that imports from `hcs.py`. ---- - -### Pitfall 5: Entry Points Lost During Migration - -**What goes wrong:** Console script entry points (`viscy = "viscy.cli:main"`) stop working after migration from setuptools to hatchling. +More subtly: if `_utils.py` imports `Sample` from `_typing.py`, and `hcs.py` imports from both `_utils.py` and `_typing.py`, the import order depends on which module is imported first. If `triplet.py` imports `hcs.py` before `_typing.py` is loaded, you get a partially initialized module. **Why it happens:** -- Different configuration syntax between setuptools and hatchling -- Mixing `[project.scripts]` and `[options.entry_points]` in same file -- Forgetting to migrate entry points at all - -**Consequences:** -- `viscy` CLI command not found after install -- Users cannot invoke tools from command line - -**Prevention:** -- Explicitly audit all `[project.scripts]` and `[project.entry-points]` sections -- Test CLI commands work after migration: `uv run viscy --help` -- For VisCy: ensure `viscy = "viscy.cli:main"` is preserved in root package - -**Detection:** After install, run the CLI command and verify it works. - -**Phase:** Address when extracting any package with CLI entry points. - -**Confidence:** MEDIUM-HIGH (multiple reports in [setuptools issues](https://github.com/pypa/setuptools/issues/4153)) +The original `hcs.py` was a single module that served as both a concrete implementation and a utility library. The README.md explicitly notes this dual role: "_hcs.py serves as both a concrete data module AND a utility library_." Extracting utilities without carefully analyzing the import dependency graph creates cycles. + +**How to avoid:** +1. Map the complete import graph BEFORE moving any code. The dependency graph in `viscy/data/README.md` is the starting point, but also trace function-level dependencies. +2. Follow a strict layering rule: + ``` + _typing.py (types only, no imports from viscy_data) + | + _utils.py (imports only from _typing, stdlib, and external libs) + | + hcs.py (imports from _typing and _utils) + | + triplet.py (imports from _typing, _utils, and hcs) + ``` +3. Test the import order explicitly: `python -c "from viscy_data import TripletDataModule"` should work without importing `hcs` first. +4. Use `ruff` rule `I001` (isort) to keep imports consistent, but also add a custom test that verifies no circular imports exist. + +**Warning signs:** +- `ImportError: cannot import name 'X' from partially initialized module` +- Tests pass when run individually but fail when run as a suite (import order dependency) +- `AttributeError` on a module object (partially loaded module) + +**Phase to address:** +Code migration phase -- specifically the `_utils.py` extraction plan. --- -## Moderate Pitfalls - -Mistakes that cause delays, confusion, or technical debt (but are recoverable). - ---- - -### Pitfall 6: Docker Build Inefficiency with Workspace Dependencies - -**What goes wrong:** Docker builds copy entire workspace for every package, causing massive cache invalidation. Any change to any package rebuilds all Docker images. - -**Why it happens:** uv requires workspace member files present to resolve dependencies. You can't just copy `uv.lock` and install third-party deps without the package sources. +### Pitfall 4: Optional Extras Create a 2^N CI Matrix Explosion -**Prevention:** -- Use `uv sync --frozen --package ` which resolves from lockfile alone (partially works) -- Structure Dockerfiles to copy minimal files first, then add sources -- Consider `--no-editable` flag when available for self-contained builds +**What goes wrong:** +With 4 optional dependency groups (`[triplet]`, `[livecell]`, `[mmap]`, `[all]`), testing all combinations across 3 Python versions and 3 OS targets creates a massive matrix: (base + triplet + livecell + mmap + all) x 3 Python x 3 OS = 45 jobs. But some combinations are invalid (pycocotools doesn't build on Windows; tensorstore has limited arm64 support on macOS). The matrix either explodes in cost or has confusing include/exclude rules. -**Detection:** Docker build times remain high even for unrelated changes. - -**Phase:** Address in Phase 4 (CI/CD optimization) or defer to later milestone. - -**Confidence:** MEDIUM (discussed in [uv issue #6935](https://github.com/astral-sh/uv/issues/6935)) +**Why it happens:** +viscy-transforms had no optional dependencies -- all deps were required. viscy-data is the first package with optional extras. The existing CI (`test.yml`) uses a simple 3x3 matrix. Naively extending it for extras creates an unmaintainable workflow. + +**How to avoid:** +1. Do NOT test all combinations. Use this strategy: + - **Base job** (no extras): 3 Python x 3 OS = 9 jobs. Tests only modules that work with base deps. + - **Full extras job** (`[all]`): 1 Python (3.12) x 1 OS (ubuntu-latest) = 1 job. Tests everything. + - **Per-extra smoke test**: 1 Python x 1 OS per extra = 3 jobs. Tests that the extra installs correctly. +2. Use pytest markers to skip tests when optional deps are missing: + ```python + tensorstore = pytest.importorskip("tensorstore") + ``` +3. Exclude known-broken combinations using the GitHub Actions matrix `exclude` key: + ```yaml + exclude: + - os: windows-latest + extras: livecell # pycocotools build fails on Windows + ``` +4. For the `[all]` extra, document that it may not install on all platforms. This is acceptable -- scientific Python packages routinely have platform limitations. + +**Warning signs:** +- CI takes >30 minutes due to matrix size +- Frequent red CI from platform-specific build failures in optional deps +- Maintainers start ignoring CI failures ("oh that's just the Windows pycocotools thing") + +**Phase to address:** +CI phase. Design the matrix before writing the workflow file. --- -### Pitfall 7: IDE Workspace Recognition Failures - -**What goes wrong:** VS Code/PyCharm don't understand uv workspace structure. Pylance shows import errors for valid workspace dependencies. Auto-complete fails. - -**Why it happens:** IDEs look for standard Python project markers. uv workspaces use different conventions than Poetry/pip. - -**Prevention:** -- Configure `.vscode/settings.json` with proper Python paths -- Use `uv sync` to ensure `.venv` exists with all packages installed -- May need to configure Pylance's `extraPaths` setting -- For PyCharm, mark `packages/*/src` as sources roots - -**Detection:** IDE shows red squiggles on valid imports between workspace packages. +### Pitfall 5: pycocotools Build Failure Blocks Entire CI on Windows -**Phase:** Address in Phase 1 (developer experience setup). +**What goes wrong:** +`pycocotools` requires a C compiler to build from source. On Ubuntu, `gcc` is available by default. On macOS, `clang` via Xcode Command Line Tools. On Windows, there is no default C compiler -- users need Visual Studio Build Tools installed. If the CI matrix includes Windows + `[livecell]` or `[all]`, the job fails at pip install time, not at test time, with a cryptic compilation error. -**Confidence:** MEDIUM (reported in [uv issue #10960](https://github.com/astral-sh/uv/issues/10960)) +**Why it happens:** +pycocotools does not always have pre-built wheels for all platform/Python version combinations. When a wheel is missing, pip falls back to building from source, which requires a C compiler. Windows GitHub Actions runners have MSVC available, but the environment may not be configured correctly for all Python versions. + +**How to avoid:** +1. Use the `pycocotools` package from conda-forge or the `pycocotools-windows` fork if targeting Windows. +2. Better: mark `[livecell]` as Linux/macOS only in documentation. LiveCell is a research dataset used primarily on HPC Linux clusters. +3. In CI, exclude the livecell extra from Windows: + ```yaml + exclude: + - os: windows-latest + python-version: "3.11" # if no wheel available + ``` +4. Alternatively, use `cython` + build isolation: `pip install pycocotools --no-build-isolation` can sometimes help, but this is fragile. +5. Pin pycocotools to a version that has wheels for your target platforms. Check PyPI for available wheels before pinning. + +**Warning signs:** +- `error: Microsoft Visual C++ 14.0 or greater is required` in CI logs +- CI green on Ubuntu/macOS, red on Windows +- Intermittent failures when new Python versions lack pre-built wheels + +**Phase to address:** +Package scaffolding phase (dependency specification) + CI phase (matrix exclusions). --- -### Pitfall 8: Version File Not Updated in Editable Installs - -**What goes wrong:** `viscy_transforms.__version__` returns stale value after git tag changes because editable installs don't rebuild version files. - -**Why it happens:** uv-dynamic-versioning (and hatch-vcs) only update version files during build, not during editable development. - -**Consequences:** -- Developers see wrong version locally -- CI may test with incorrect version metadata -- Version checks in code behave unexpectedly +### Pitfall 6: iohub API Coupling Creates Fragile Type Boundaries -**Prevention:** -- Don't rely on `__version__` in runtime code paths -- If needed, use `importlib.metadata.version("viscy-transforms")` instead -- Rebuild package before version-sensitive testing +**What goes wrong:** +The data modules use iohub's `Position`, `Plate`, `Well`, and `ImageArray` types extensively -- not just for I/O, but as type annotations on public methods and in constructor signatures. If iohub releases a breaking change (e.g., renaming `Position` to `FOV`, or changing the `ImageArray` interface), every data module breaks simultaneously. More immediately: if the viscy-data pyproject.toml pins `iohub>=0.X` but a user has `iohub==0.X-1`, they get confusing `AttributeError`s instead of a clean version conflict. -**Detection:** `python -c "import viscy_transforms; print(viscy_transforms.__version__)"` shows old version. - -**Phase:** Document in developer guide; not critical for Phase 1. - -**Confidence:** MEDIUM (noted in [hatch-vcs documentation](https://pypi.org/project/hatch-vcs/)) +**Why it happens:** +iohub is developed by the same team (CZ Biohub), so API stability was implicitly assumed. The tight coupling is intentional -- these types ARE the domain model. But as a separately packaged library, iohub's release cycle is now decoupled from viscy-data's. + +**How to avoid:** +1. Pin iohub with a minimum version that has the API you depend on: `iohub>=0.2.0` (or whatever version stabilized the `Position`/`Plate` API). +2. DO NOT pin an upper bound (`iohub<1.0`) -- this causes resolver hell for users. Trust semantic versioning. +3. Add an integration test that imports all iohub types used by viscy-data and verifies they have the expected attributes. This catches API drift early: + ```python + def test_iohub_api_surface(): + from iohub.ngff import Position, Plate, ImageArray + assert hasattr(Position, "__getitem__") # etc. + ``` +4. Document which iohub version was tested against in the README. + +**Warning signs:** +- iohub release notes mention "breaking changes" or "renamed" +- Users report `AttributeError` on iohub objects +- `uv lock` resolves a newer iohub than was tested + +**Phase to address:** +Package scaffolding phase (dependency pinning). Integration test in test migration phase. --- -### Pitfall 9: Namespace Package Migration Requires Simultaneous Update +### Pitfall 7: ThreadDataLoader from MONAI Breaks Isolation Testing -**What goes wrong:** If VisCy kept `viscy.transforms` as a namespace package allowing both old and new code to coexist, all packages sharing that namespace must use identical `__init__.py` files. +**What goes wrong:** +`TripletDataModule` uses `monai.data.ThreadDataLoader` instead of PyTorch's `DataLoader`. When running `uv sync --package viscy-data` for isolated testing, the test environment has MONAI installed (it's a required dep). But `ThreadDataLoader` has threading behavior that interacts badly with pytest's test isolation -- specifically, thread-local state can leak between tests, and `tensorstore`'s async I/O in threads can deadlock if the event loop is not properly managed. -**Why it happens:** Python's namespace package mechanism (pkgutil or pkg_resources style) requires consistency across all packages using the namespace. +More specifically: `ThreadDataLoader` creates `ThreadPoolExecutor` workers instead of subprocess workers. These threads share the GIL and the process's memory space. If a test creates a `ThreadDataLoader` and doesn't explicitly shut it down, the threads persist into the next test, causing resource leaks and eventual `OSError: too many open files`. -**Consequences:** -- Import failures -- "Namespace package breaks module imports" errors -- Partial imports work, others fail randomly - -**Prevention:** -- VisCy chose clean break approach (good decision) -- `from viscy_transforms import X` not `from viscy.transforms import X` -- No namespace packages, no coordination required - -**Detection:** Would manifest as inconsistent import errors. - -**Phase:** N/A for VisCy (already decided on clean break). - -**Confidence:** HIGH (documented in [Python Packaging Guide](https://packaging.python.org/en/latest/guides/packaging-namespace-packages/)) +**Why it happens:** +`ThreadDataLoader` was chosen for DynaCLR/triplet because tensorstore performs async I/O that releases the GIL. Thread-based workers are more efficient than subprocess workers for GIL-releasing I/O. But this design choice has testing implications that aren't obvious until you run a full test suite. + +**How to avoid:** +1. Use pytest fixtures that explicitly create and tear down DataLoaders: + ```python + @pytest.fixture + def triplet_dataloader(triplet_datamodule): + triplet_datamodule.setup("fit") + loader = triplet_datamodule.train_dataloader() + yield loader + # Explicit cleanup + if hasattr(loader, '_executor'): + loader._executor.shutdown(wait=False) + ``` +2. Run triplet-related tests in a separate pytest session or mark them with `@pytest.mark.forked` (requires `pytest-forked`). +3. Set `num_workers=0` in test fixtures to avoid threading entirely. Reserve `num_workers>0` tests for integration/slow test marks. +4. Add resource leak detection: `pytest --tb=short -W error::ResourceWarning`. + +**Warning signs:** +- Tests hang indefinitely when run as a full suite but pass individually +- `OSError: [Errno 24] Too many open files` in CI +- Intermittent test failures ("flaky tests") that depend on test execution order + +**Phase to address:** +Test migration phase. Configure fixtures before migrating test files. --- -### Pitfall 10: Optional Dependencies Conflicting Across Groups - -**What goes wrong:** `viscy[dev]` includes `onnxruntime` but a future `viscy[gpu]` extra needs `onnxruntime-gpu`. These packages conflict and cannot be installed together. - -**Why it happens:** PyPI packages can have mutually exclusive variants. uv resolves all extras together by default. - -**Prevention:** -- Use `[tool.uv.conflicts]` to declare mutually exclusive extras: - ```toml - [tool.uv] - conflicts = [ - [ - { extra = "cpu" }, - { extra = "gpu" }, - ] - ] - ``` -- Document which extras can be combined -- Consider separate packages instead of conflicting extras - -**Detection:** `uv lock` fails when conflicting extras exist without conflict declaration. - -**Phase:** Address when defining extras for extracted packages. +## Moderate Pitfalls -**Confidence:** HIGH (documented in [uv dependencies docs](https://docs.astral.sh/uv/concepts/projects/dependencies/)) +Mistakes that cause delays, confusion, or technical debt but are recoverable. --- -### Pitfall 11: CI Cache Explosion in Monorepos - -**What goes wrong:** Every PR creates its own cache copy of `.venv` and `~/.cache/uv`. GitHub Actions storage fills up. Build times remain slow despite caching. - -**Why it happens:** Default cache key includes PR-specific identifiers. No shared baseline cache. - -**Prevention:** -- Use `uv cache prune --ci` before saving cache (removes pre-built wheels) -- Share cache across PRs using workflow-level cache key -- Consider weekly cache expiration -- Use `astral-sh/setup-uv` with smart cache management - -**Detection:** GitHub Actions cache usage dashboard shows high storage; cache hit rate is low. +### Pitfall 8: `__init__.py` Re-exports Create Eager Import Chains -**Phase:** Address in Phase 4 (CI optimization). +**What goes wrong:** +A natural approach for `viscy_data/__init__.py` is to re-export all public classes: +```python +from viscy_data.hcs import HCSDataModule +from viscy_data.triplet import TripletDataModule +from viscy_data.livecell import LiveCellDataModule +``` +But `triplet.py` has `import tensorstore` (even if guarded), and `livecell.py` has `import pycocotools`. If the guard fails or is at module level, `import viscy_data` itself fails for users who only installed the base package without extras. -**Confidence:** MEDIUM (discussed in [uv issue #2231](https://github.com/astral-sh/uv/issues/2231)) +**Why it happens:** +viscy-transforms got away with eager re-exports because all its dependencies are required. viscy-data has optional deps that make eager re-exports dangerous. + +**How to avoid:** +1. Only re-export classes whose modules have no optional dependencies in `__init__.py`: + ```python + # viscy_data/__init__.py + from viscy_data.hcs import HCSDataModule, SlidingWindowDataset + from viscy_data.gpu_aug import GPUTransformDataModule + from viscy_data.combined import CombinedDataModule + from viscy_data.distributed import ShardedDistributedSampler + # Do NOT import from triplet, livecell, mmap_cache at top level + ``` +2. For optional-dep modules, use `__all__` and document the import path: + ```python + # Users must import explicitly: + # from viscy_data.triplet import TripletDataModule + ``` +3. Alternatively, use `__getattr__` for lazy module-level imports (PEP 562): + ```python + def __getattr__(name): + if name == "TripletDataModule": + from viscy_data.triplet import TripletDataModule + return TripletDataModule + raise AttributeError(f"module 'viscy_data' has no attribute {name}") + ``` + +**Warning signs:** +- `import viscy_data` fails on a fresh install without `[all]` +- Users report `ModuleNotFoundError: No module named 'tensorstore'` when they only wanted `HCSDataModule` + +**Phase to address:** +Package scaffolding phase (design `__init__.py` strategy before code migration). --- -### Pitfall 12: GitHub Pages Jekyll Interference - -**What goes wrong:** Sphinx documentation with `_static/` and `_templates/` directories doesn't deploy correctly to GitHub Pages. - -**Why it happens:** Jekyll (GitHub Pages default) ignores directories starting with underscore. - -**Prevention:** -- Add `.nojekyll` file to gh-pages branch root -- Configure GitHub Actions to create this file automatically -- Use `actions/deploy-pages` with proper configuration - -**Detection:** CSS/JS missing on deployed docs site; 404 errors for `_static/` files. - -**Phase:** Address in Phase 2 (documentation setup). - -**Confidence:** HIGH (well-documented [Sphinx to GitHub Pages issue](https://lornajane.net/posts/2025/publish-to-github-pages-with-sphinx)) +### Pitfall 9: Zarr/iohub Test Fixtures Are Expensive and Non-Trivial ---- +**What goes wrong:** +Data module tests require actual OME-Zarr stores with HCS plate structure (plates > wells > FOVs > images). Creating these fixtures is not trivial -- it requires iohub to write proper OME-Zarr metadata, multiple resolution levels, and channel metadata. If each test creates its own fixture, the test suite becomes extremely slow. If fixtures are shared (session-scoped), tests can interfere with each other through mutations. -## Minor Pitfalls +Additionally, tensorstore tests need properly structured Zarr arrays, and livecell tests need COCO-format JSON annotations plus TIFF images. These are three different fixture ecosystems within one package. -Annoyances that are easily fixable but worth knowing about. +**Why it happens:** +viscy-transforms tests only needed tensor fixtures (easy: `torch.randn(1, 1, 32, 32)`). Data module tests need filesystem-backed fixtures with specific directory structures and metadata. This is a qualitative jump in fixture complexity. + +**How to avoid:** +1. Create a `conftest.py` with session-scoped, read-only fixtures: + ```python + @pytest.fixture(scope="session") + def ome_zarr_store(tmp_path_factory): + """Create a minimal HCS OME-Zarr store for testing.""" + store_path = tmp_path_factory.mktemp("data") / "test.zarr" + # Use iohub to create a proper HCS plate + from iohub.ngff import open_ome_zarr + with open_ome_zarr(store_path, layout="hcs", mode="w") as plate: + position = plate.create_position("A", "1", "0") + position.create_image("0", data=np.random.rand(1, 2, 5, 64, 64)) + return store_path + ``` +2. Use `tmp_path_factory` (session-scoped) not `tmp_path` (function-scoped) for expensive I/O fixtures. +3. Mark tests that need real I/O fixtures with `@pytest.mark.slow` and skip them in the fast CI job. +4. For livecell: create a minimal COCO JSON fixture as a Python dict, write it to a temp file. Do not download real LiveCell data in CI. +5. NEVER use real data paths in tests. The existing Hydra configs reference `/hpc/projects/...` paths that are HPC-specific. + +**Warning signs:** +- Test suite takes >5 minutes due to fixture creation +- Tests fail on CI but pass locally (missing data files) +- Flaky tests due to shared mutable fixtures + +**Phase to address:** +Test migration phase. Design fixture strategy BEFORE writing test files. --- -### Pitfall 13: Extra Name Normalization - -**What goes wrong:** Extra named `foo_bar` must be installed as `pip install pkg[foo-bar]` (hyphen, not underscore). - -**Why it happens:** PEP 503 normalizes package and extra names, converting underscores to hyphens. +### Pitfall 10: Lightning CLI / Hydra Config Class Paths Break Silently -**Prevention:** -- Use hyphens in extra names from the start -- Document the correct extra names in README +**What goes wrong:** +Downstream training configs (Hydra YAML, Lightning CLI YAML) reference data modules by fully qualified class path: +```yaml +# Old path (broken after extraction) +data: + class_path: viscy.data.hcs.HCSDataModule -**Detection:** `pip install viscy[foo_bar]` fails with "extra not found". +# New path (correct) +data: + class_path: viscy_data.hcs.HCSDataModule +``` +The breakage is silent -- configs are just YAML files, so no linter or type checker catches the stale path. The error only appears when someone runs training, potentially weeks after the extraction. -**Phase:** Address during pyproject.toml authoring. +Hydra is explicitly out of scope per PROJECT.md, but Lightning CLI is used by the training pipelines. The existing Hydra output configs in `applications/dynacell/outputs/` show the config structure but don't reference class paths (they use nested config, not `_target_`). However, Lightning CLI configs DO use `class_path`. -**Confidence:** HIGH (documented in [recursive optional dependencies article](https://hynek.me/articles/python-recursive-optional-dependencies/)) +**Why it happens:** +Config files are stringly-typed. Import path changes are invisible to them. The v1.0 extraction of viscy-transforms did not have this problem because transforms are passed as constructor arguments (MONAI `Compose`), not referenced by class path in configs. + +**How to avoid:** +1. Search all YAML/JSON files for `viscy.data` references: + ```bash + grep -r "viscy\.data\." applications/ examples/ configs/ --include="*.yaml" --include="*.json" + ``` +2. Create a migration guide document listing old -> new import paths for every public class. +3. Add a deprecation shim module (even though clean break is the policy): + ```python + # viscy/data/__init__.py (in the umbrella package, if it exists) + import warnings + warnings.warn( + "viscy.data is deprecated. Use viscy_data instead. " + "See migration guide: https://...", + DeprecationWarning, stacklevel=2 + ) + from viscy_data import * + ``` + This is optional and contradicts the "clean break" decision, but it prevents silent failures for existing users. +4. If clean break is firm (per PROJECT.md): ensure all known configs in the repository are updated in the same PR that extracts the package. + +**Warning signs:** +- Training scripts fail with `ModuleNotFoundError` or `ClassNotFoundError` weeks after extraction +- Users open issues about broken configs +- Saved experiment configs become non-reproducible + +**Phase to address:** +Code migration phase (update all in-repo configs). Document in a migration guide during docs phase. --- -### Pitfall 14: src Layout Import Confusion - -**What goes wrong:** Developer runs `python -c "import viscy_transforms"` from repo root and gets `ModuleNotFoundError`. - -**Why it happens:** src layout requires package to be installed. Can't import directly from source tree. +### Pitfall 11: `SelectWell` Mixin + Multiple Inheritance MRO Fragility -**Prevention:** -- Always use `uv run python -c "..."` instead of bare `python` -- Document that `uv sync` is required before any testing -- This is intentional — prevents testing uninstalled code +**What goes wrong:** +`CachedOmeZarrDataModule(GPUTransformDataModule, SelectWell)` and `MmappedDataModule(GPUTransformDataModule, SelectWell)` use multiple inheritance with a mixin. During extraction, if the base classes are reorganized or their `__init__` signatures change, Python's Method Resolution Order (MRO) can break. Specifically: if `GPUTransformDataModule.__init__` calls `super().__init__()` but `SelectWell.__init__` expects different arguments, you get `TypeError: __init__() got an unexpected keyword argument`. -**Detection:** Import errors when running Python directly instead of through uv. - -**Phase:** Document in developer guide. - -**Confidence:** HIGH (intentional design of src layout) +**Why it happens:** +Multiple inheritance with `super()` requires cooperative `__init__` chains. If any class in the MRO doesn't properly forward `**kwargs`, the chain breaks. This is fragile even without extraction, but extraction increases the risk because developers may refactor `__init__` signatures to "clean up" the extracted code. + +**How to avoid:** +1. Do NOT change `__init__` signatures during extraction. Copy first, refactor later. +2. Add explicit MRO tests: + ```python + def test_cached_ome_zarr_mro(): + mro = CachedOmeZarrDataModule.__mro__ + assert mro.index(GPUTransformDataModule) < mro.index(SelectWell) + ``` +3. Ensure all mixins accept `**kwargs` and forward them to `super().__init__(**kwargs)`. +4. Document the inheritance hierarchy in the package README (the existing mermaid diagram in `viscy/data/README.md` is excellent -- preserve it). + +**Warning signs:** +- `TypeError: __init__() got an unexpected keyword argument` when constructing DataModules +- Tests pass for base classes but fail for subclasses +- Behavior changes when import order changes (MRO is import-order-independent, but some metaclass tricks are not) + +**Phase to address:** +Code migration phase. Copy-first, refactor-never (during extraction). --- -### Pitfall 15: Forgetting to Declare Workspace Dependencies - -**What goes wrong:** Package A depends on Package B but forgets `{ workspace = true }` in sources. Resolution uses PyPI version instead of local version. - -**Why it happens:** Easy to forget the explicit workspace source declaration. - -**Prevention:** -- Template check: every inter-package dependency needs two parts: - ```toml - [project] - dependencies = ["viscy-transforms>=0.1"] - - [tool.uv.sources] - viscy-transforms = { workspace = true } - ``` -- CI should verify workspace packages resolve locally +### Pitfall 12: tensordict MemoryMappedTensor Cleanup in Tests -**Detection:** `uv lock` downloads from PyPI instead of using local package. +**What goes wrong:** +`MmappedDataModule` creates `MemoryMappedTensor` objects backed by files in a scratch directory. These memory-mapped files hold open file descriptors. In tests, if the fixture doesn't explicitly close/unmap these tensors, you get: (a) `PermissionError` on Windows when pytest tries to clean up `tmp_path`, (b) memory leaks in CI, (c) stale memory-mapped files accumulating in `/tmp` on long-running test sessions. -**Phase:** Address with each package extraction. - -**Confidence:** HIGH (documented in [uv workspaces docs](https://docs.astral.sh/uv/concepts/projects/workspaces/)) - ---- - -## Phase-Specific Warnings - -| Phase | Topic | Likely Pitfall | Mitigation | -|-------|-------|----------------|------------| -| 1 | Workspace setup | requires-python intersection | Agree on floor (3.11) before starting | -| 1 | Build system | Wrong build backend | Use `hatchling.build`, never `uv` | -| 1 | Initial structure | Import leakage | Test packages in isolation from day 1 | -| 2 | Documentation | Jekyll blocking `_static` | Add `.nojekyll` to deploy workflow | -| 2 | API docs | Version not updating | Use importlib.metadata for runtime version | -| 3 | Package extraction | Entry points lost | Audit and test CLI commands | -| 3 | Dependencies | Conflicting numpy/torch versions | Pin compatible ranges early | -| 4 | CI/CD | Cache explosion | Use `uv cache prune --ci` | -| 4 | Docker | Full workspace copy | Use `--frozen --package` where possible | -| 5+ | Multiple extras | Conflicting extras | Declare conflicts in tool.uv | +**Why it happens:** +Memory-mapped files are OS resources, not Python objects managed by the garbage collector. `del tensor` doesn't immediately release the mmap.

NumPy 2.0 migration is ongoing in the scientific Python ecosystem. - -**Mitigation:** -- Pin NumPy range that's compatible with PyTorch 2.4+ -- Test against NumPy 1.x and 2.x in CI -- Monitor [NumPy 2.0 ecosystem compatibility](https://github.com/numpy/numpy/issues/26191) - -### Risk 2: MONAI + Kornia Dependency Conflicts - -Both MONAI and Kornia have their own torch dependencies. Version mismatches can cause subtle runtime errors. - -**Mitigation:** -- Run `uv tree` to inspect resolved versions -- Test with exact locked versions before release - -### Risk 3: Clean Break Import Migration - -Applications and examples will have broken imports (`from viscy.transforms import X`).

This is a pre-release version (alpha), which means the API may not be fully stable. However, VisCy has been using this version in production. The `[tensorstore]` extra on iohub itself is separate from our optional `[triplet]` extra -- iohub uses tensorstore for its own OME-Zarr v0.5 sharded access. We should pin `iohub>=0.3a2` as the base dependency and let users who need tensorstore-backed I/O install `viscy-data[triplet]` which includes both. -### Documentation +**Rationale for monai >=1.5.2 (not >=1.4):** The original VisCy pinned >=1.4, but viscy-transforms already uses >=1.5.2.

The recommended approach uses **hatchling + hatch-vcs + hatch-cada** for build and versioning, replacing the current setuptools + setuptools-scm configuration. The first extraction targets `viscy-transforms` (GPU augmentation transforms), establishing patterns for future extractions. +The viscy-data package extraction involves migrating 13 data loading modules from the VisCy monolith into a standalone workspace package. This is the second extraction milestone, building on the established patterns from viscy-transforms (Milestone 1). The extraction is architecturally straightforward — copy modules, update imports, declare dependencies — but has three significant complexities that distinguish it from viscy-transforms: (1) heavy I/O dependencies (iohub, zarr, tensorstore) with platform-specific constraints, (2) optional heavyweight dependencies requiring careful lazy loading, and (3) a one-way cross-package dependency on viscy-transforms for `BatchedCenterSpatialCropd`. -The monorepo approach enables users to install only what they need (`pip install viscy-transforms` instead of the entire VisCy stack), reduces dependency bloat, and allows independent release cycles. Critical to success: agreeing on a single Python version floor (3.11+) across all workspace members, preventing import leakage via isolated testing, and using src layout to avoid development-time import confusion. The architecture requires careful dependency management since all packages share a single lockfile. +The recommended approach follows the proven viscy-transforms pattern: flat module layout with underscore-prefixed private modules, top-level exports in `__init__.py`, optional dependency groups (`[triplet]`, `[livecell]`, `[mmap]`, `[all]`), and workspace dependency declaration. The critical difference is extracting shared utilities from `hcs.py` into `_utils.py` FIRST — this breaks the current dual-role pattern where hcs.py serves as both a concrete DataModule and a utility library, preventing fragile cross-module coupling. -Key risks center on the shared lockfile constraint (conflicting dependencies between packages break the workspace) and the clean break in import paths (`from viscy_transforms import X` not `from viscy.transforms import X`). Applications and examples will have temporarily broken imports until updated. Mitigation requires phase-gated extraction with validation at each step, comprehensive CI testing per package, and clear migration documentation for downstream users. +Key risks center on multiprocessing and cross-platform compatibility: the `Manager().dict()` shared cache pattern works on Linux (fork) but breaks on macOS/Windows (spawn), optional dependencies like pycocotools and tensorstore have platform-specific build requirements, and `ThreadDataLoader` with tensorstore creates test isolation challenges. These are mitigated by: (1) testing with `spawn` explicitly in CI, (2) using optional dependency groups with platform markers, (3) session-scoped test fixtures with explicit cleanup, and (4) a tiered CI matrix (base deps on 3x3, full extras on 1x1). ## Key Findings ### Recommended Stack -The stack modernizes VisCy's tooling while maintaining compatibility with the scientific Python ecosystem. Core shift: **hatchling replaces setuptools** because it's extensible via plugins and integrates cleanly with uv workspaces. Dynamic versioning uses **hatch-vcs (git tag based) + hatch-cada (workspace dependency rewriting)** instead of setuptools-scm. This combination enables independent package versioning with tags like `viscy-transforms@1.0.0` while correctly handling inter-package dependencies at build time. +The core stack is **iohub + monai + lightning + torch + numpy** as required dependencies, with **tensorstore, tensordict, pycocotools, pandas, tifffile, torchvision** available through optional extras. This represents an incremental addition to the workspace — the build system (hatchling + uv-dynamic-versioning), Python version support (3.11-3.14), and CI patterns are already established and do not need re-research. **Core technologies:** -- **uv** (package manager, workspace orchestration) — 10-100x faster than pip, native workspace support, industry standard for 2025+ -- **hatchling + hatch-vcs + hatch-cada** (build system + versioning) — Plugin-based extensibility; hatch-cada critical for workspace deps; hatch-vcs mature git versioning -- **Zensical** (documentation) — Official successor to Material for MkDocs (now in maintenance mode); 4-5x faster builds; Rust + Python -- **ruff** (linting + formatting) — Replaces black + isort + flake8; 200x faster; native Jupyter support; current project already uses it +- **iohub >=0.3a2**: OME-Zarr I/O layer (Plate, Position, ImageArray) used by 9 of 13 modules; pre-release version but stable in VisCy production use +- **monai >=1.5.2**: Transforms (Compose, MapTransform), data utilities (ThreadDataLoader, set_track_meta, collate_meta_tensor) used by 10 of 13 modules; aligns with viscy-transforms pin +- **lightning >=2.3**: LightningDataModule base class for all data modules; matches original VisCy pin +- **torch >=2.10**: Tensor operations, DataLoader, Dataset; aligns with viscy-transforms for consistency +- **tensorstore (optional)**: High-performance array I/O for contrastive learning triplet cache; C++ library with platform wheel limitations; only needed for `[triplet]` extra +- **tensordict (optional)**: MemoryMappedTensor for mmap caching strategy; part of PyTorch RL ecosystem; only needed for `[mmap]` extra +- **pycocotools (optional)**: COCO annotation parsing for LiveCell benchmark dataset; requires C compiler on some platforms; only needed for `[livecell]` extra -**Note:** Cannot use uv's native build backend (`build-backend = "uv"`) because it doesn't support plugins yet. Hatchling required for hatch-vcs/hatch-cada functionality. +**Version pinning philosophy:** Floor pins (`>=X.Y`) for core dependencies to avoid over-constraining user environments. No upper bounds (trust semantic versioning). No version pins for optional dependencies — let the resolver pick compatible versions. ### Expected Features +All 13 modules must be extracted and importable with clean paths (`from viscy_data import HCSDataModule`). The extraction must preserve all existing functionality while establishing a cleaner architecture through utility refactoring. Optional dependency groups enable users to install only what they need for their specific pipeline (translation, FCMAE pretraining, contrastive learning, or benchmarking). + **Must have (table stakes):** -- **Workspace member discovery** — `members = ["packages/*"]` glob pattern; users expect this to work -- **Shared lockfile** — Single `uv.lock` ensures reproducibility; standard uv workspace design -- **Editable inter-package dependencies** — `workspace = true` in sources; changes propagate immediately during development -- **Per-package testing** — `uv run --package viscy-transforms pytest` must work from any directory -- **Git-based versioning** — Dynamic version from VCS tags; avoids manual version bumps (scientific Python standard) -- **src layout** — `packages/*/src/*/` prevents import confusion; pytest/pip best practice -- **CI changed-package filtering** — Path-based filtering; don't test unchanged packages (monorepo efficiency requirement) +- All 13 modules extracted with clean import paths (no `viscy.data.` references) +- Flat top-level exports for all DataModules and Datasets +- Type exports (Sample, NormMeta, TripletSample, etc.) for downstream type annotations +- Optional dependency groups (`[triplet]`, `[livecell]`, `[mmap]`, `[all]`) +- Workspace dependency on viscy-transforms (for `BatchedCenterSpatialCropd` import in triplet.py) +- Shared utilities extracted from hcs.py into `_utils.py` (breaks dual-role anti-pattern) +- Existing tests passing under new import paths +- py.typed marker for type checking support **Should have (competitive):** -- **Reusable CI workflows** — DRY GitHub Actions with parameters; reduces maintenance overhead -- **API documentation generation** — Auto-generated from docstrings (mkdocstrings/Zensical); keeps docs synchronized -- **Package-specific documentation** — Per-package docs with cross-linking; docs stay close to code -- **Parallel test execution** — pytest-xdist for faster runs; easy win for large test suites -- **Independent versioning** — Each package has own version via package-specific tags; good for loosely coupled packages +- Lazy imports for heavy optional deps with clear error messages when missing +- Package README with pipeline mapping table (adapted from existing `viscy/data/README.md`) +- GPU transform mixin as protocol for duck typing without forced inheritance +- Type-safe batch structures exported as first-class types **Defer (v2+):** -- **Release automation** — python-semantic-release or manual workflow; manual releases acceptable initially -- **Coverage aggregation** — Combined coverage across packages; nice-to-have for later -- **Dependabot/Renovate** — Automated dependency updates; can add after initial stabilization -- **Dev containers** — Consistent environment via devcontainer.json; useful but not blocking +- Promoting internal utilities like `_read_norm_meta` to public API (wait for user demand) +- Abstract cache interface unifying Manager.dict, tensorstore, and MemoryMappedTensor patterns (complexity without immediate benefit) +- Config-driven DataModule registry for Lightning CLI integration (wait for viscy meta-package) ### Architecture Approach -The architecture uses a **virtual workspace root** (not a distributable package) that coordinates multiple independent packages under `packages/*`. Each package uses src layout (`packages//src//`) with its own pyproject.toml, preventing import confusion and enabling true independence. The single lockfile at workspace root ensures consistent dependency resolution, while workspace dependencies declared via `[tool.uv.sources]` with `workspace = true` enable editable development. +The package uses a flat module layout following the viscy-transforms pattern. All modules use underscore-prefixed names (`_hcs.py`, `_utils.py`) to signal "import from package top-level, not from module." The internal dependency graph is a clean DAG with foundation modules (`_typing.py`, `_utils.py`) at the root, core modules (`hcs.py`, `gpu_aug.py`) in the middle, and specialized modules (triplet, livecell, mmap_cache) as leaves. **Major components:** -1. **Workspace Root** — Defines membership via `[tool.uv.workspace]`, shared tooling config (ruff, mypy, pytest), not installable itself -2. **viscy-transforms (first extraction)** — Image transformations (kornia, monai based); standalone with no workspace dependencies -3. **viscy-data (future)** — Data loading, HCS datasets; may depend on viscy-transforms via workspace sources -4. **viscy-models (future)** — Neural network architectures; may depend on viscy-transforms -5. **applications/** — Publication code (not a package); broken imports acceptable during transition -**Critical path:** Workspace scaffolding → First package extraction → Code migration → Test migration. Phases 5+ (dependency groups) and 6 (dynamic versioning) can run in parallel after Phase 2 completes. +1. **Foundation layer** (`_typing.py`, `_utils.py`) — Type definitions and shared utilities; no internal dependencies; imported by all other modules +2. **Core DataModules** (`hcs.py`, `gpu_aug.py`) — HCSDataModule for translation pipelines, GPUTransformDataModule (ABC) for FCMAE pretraining; depend only on foundation layer +3. **Specialized DataModules** (triplet, mmap_cache, livecell, cell_classification, cell_division_triplet, ctmc_v1, segmentation) — Pipeline-specific implementations extending core DataModules; may have optional dependencies +4. **Composition modules** (combined, concat) — Wrappers for multi-source training and dataset concatenation; depend on core modules +5. **Utilities** (select, distributed) — SelectWell mixin for well/FOV filtering, ShardedDistributedSampler for DDP; standalone with no internal dependencies + +**Critical architecture decision:** Extract shared utilities (`_ensure_channel_list`, `_read_norm_meta`, `_collate_samples`) from `hcs.py` into `_utils.py` BEFORE extracting any other modules. The current code has 5 modules importing from `hcs.py` for utility functions, not for `HCSDataModule`, creating unnecessary coupling. This refactoring is the prerequisite that enables clean module boundaries. ### Critical Pitfalls -1. **Single requires-python constraint** — uv enforces workspace-wide Python version intersection. If one package needs 3.12+, entire workspace becomes 3.12+. Users on 3.11 cannot install any package even if individually compatible. **Mitigation:** Agree on Python 3.11 floor upfront; document in workspace root; all packages must use `>=3.11`. +Based on analysis of the 13-module architecture, v1.0 extraction experience, and domain expertise with PyTorch/Lightning data loading patterns: + +1. **Lazy Import Guard Ordering Breaks at Runtime** — Optional dependencies (tensorstore, tensordict, pycocotools) must use lazy imports that defer errors until actual usage, not module import time. If guards are missing or placed incorrectly, errors surface deep in training loops (potentially in DataLoader worker subprocesses), making them hard to trace. Prevention: centralized lazy import pattern in `_imports.py`, call import helpers at method entry points, test with base-deps-only CI job to catch unguarded imports. -2. **Conflicting dependencies between members** — All packages share one lockfile. If viscy-transforms needs `numpy<2` and a future package needs `numpy>=2`, resolution fails and workspace cannot lock. **Mitigation:** Survey dependency constraints before adding packages; pin compatible ranges for PyTorch/NumPy early; consider path dependencies for genuinely incompatible packages. +2. **Manager().dict() Shared Cache Not Picklable Across spawn Contexts** — `CachedOmeZarrDataset` uses `multiprocessing.Manager().dict()` which works with `fork` (Linux) but fails with `spawn` (macOS/Windows default). Proxy objects must pickle, and depending on creation timing relative to DataLoader fork/spawn, you get either pickle errors or silently separate caches per worker. Prevention: create Manager in `setup()` (Lightning hook after multiprocessing context is configured), test with `mp_start_method="spawn"` explicitly in CI, consider replacing with file-based cache. -3. **Import leakage between workspace members** — Python doesn't enforce dependency boundaries. viscy-transforms can accidentally import from viscy-data even without declaring it, because both are in the same environment. Works in monorepo, fails for users. **Mitigation:** Test each package in isolation (`uv sync --package `); CI must test packages independently, not just whole workspace. +3. **Base Class Extraction Creates Hidden Import Cycles** — `hcs.py` is both a concrete DataModule and the base class for TripletDataModule/CellDivisionTripletDataModule. Extracting utilities into `_utils.py` without careful dependency analysis creates circular imports. Prevention: map complete import graph BEFORE moving code, follow strict layering (_typing -> _utils -> hcs -> specialized), test import order explicitly with isolated `python -c "from viscy_data import X"` calls. -4. **uv-dynamic-versioning requires hatchling** — Using `build-backend = "uv"` breaks dynamic versioning; uv-dynamic-versioning is a hatchling plugin. **Mitigation:** Always use `build-backend = "hatchling.build"`; verify version in built wheel before publishing. +4. **Optional Extras Create a 2^N CI Matrix Explosion** — With 4 optional groups across 3 Python versions and 3 OS targets, testing all combinations creates 45+ jobs. Some combinations are invalid (pycocotools doesn't build on Windows). Prevention: tiered CI strategy (base deps 3x3, full extras 1x1, per-extra smoke tests), use pytest markers to skip when deps missing, exclude known-broken combinations in matrix. -5. **Entry points lost during migration** — CLI commands (`viscy = "viscy.cli:main"`) stop working after setuptools → hatchling. Different config syntax; easy to forget. **Mitigation:** Audit all `[project.scripts]` sections; test CLI after migration: `uv run viscy --help`. +5. **pycocotools Build Failure Blocks Windows CI** — pycocotools requires C compiler; Windows has no default C compiler. When wheels are missing, pip falls back to source build which fails. Prevention: exclude livecell extra from Windows in CI matrix, mark `[livecell]` as Linux/macOS only in docs (LiveCell is HPC dataset anyway), or use `pycocotools-windows` fork. ## Implications for Roadmap -Based on research, suggested phase structure: +Based on the dependency analysis and architecture patterns, the extraction follows a layered build order. The critical path is: scaffolding → foundation modules → core modules → specialized modules → composition modules → finalize. Tests can begin after core modules are migrated. -### Phase 1: Workspace Foundation -**Rationale:** Establishes monorepo structure and prevents critical pitfalls (Python version floor, build system). Must come first because all packages depend on workspace configuration. +### Phase 1: Package Scaffolding & Foundation +**Rationale:** Establish package structure and dependency declarations before migrating any code. Extract shared utilities first to break the hcs.py dual-role anti-pattern. **Delivers:** -- Root pyproject.toml with `[tool.uv.workspace]` and `members = ["packages/*"]` -- Shared tooling config (ruff, mypy, pytest at workspace level) -- Python version floor decision (3.11+) documented -- Virtual workspace root (`package = false`) +- `packages/viscy-data/pyproject.toml` with all dependencies (required and optional groups) +- Empty `__init__.py` placeholder +- `py.typed` marker +- `_typing.py` with all data types (verbatim copy from `viscy/data/typing.py` + DictTransform alias) +- `_utils.py` with extracted helpers (`_ensure_channel_list`, `_read_norm_meta`, `_collate_samples`, `_search_int_in_str`) +- Root `pyproject.toml` updated with viscy-data workspace dependency + +**Addresses features:** +- Package structure (table stakes) +- Type exports (table stakes) +- Shared utilities extraction (table stakes, prevents coupling) +- Optional dependency groups (table stakes) -**Addresses:** -- Workspace scaffolding (table stakes from FEATURES.md) -- Shared lockfile requirement -- Pre-commit/prek hooks for quality gates - -**Avoids:** -- Pitfall #1 (Python version conflicts) by setting floor upfront -- Pitfall #4 (wrong build backend) by configuring hatchling immediately +**Avoids pitfalls:** +- P3 (import cycles) — extracting _utils.py first prevents coupling +- P1 (lazy imports) — pyproject.toml defines extras structure +- P5 (pycocotools Windows) — optional deps with platform markers -### Phase 2: viscy-transforms Package Extraction -**Rationale:** First extraction establishes patterns for future packages. viscy-transforms chosen because it's standalone (no workspace dependencies), well-isolated, and delivers immediate user value. +### Phase 2: Core Data Modules +**Rationale:** Migrate the two base DataModule classes that other modules depend on. These have no optional dependencies and establish the inheritance patterns. **Delivers:** -- `packages/viscy-transforms/` with src layout -- Per-package pyproject.toml with hatchling + hatch-vcs + hatch-cada -- Git-based versioning configured (tag pattern: `viscy-transforms@X.Y.Z`) -- Clean import path: `from viscy_transforms import X` +- `hcs.py` (HCSDataModule, SlidingWindowDataset, MaskTestDataset) — remove extracted functions, update imports +- `gpu_aug.py` (GPUTransformDataModule ABC, CachedOmeZarrDataset, CachedOmeZarrDataModule) — update imports to viscy_data._utils +- `select.py` (SelectWell mixin) — verbatim copy, update imports +- `distributed.py` (ShardedDistributedSampler) — verbatim copy, no internal imports -**Uses:** -- hatchling build backend -- hatch-vcs for version from git tags -- hatch-cada for workspace dependency rewriting -- PEP 735 dependency groups for dev/test separation +**Uses stack:** iohub, monai, lightning, torch (all required deps) -**Implements:** -- src layout pattern from ARCHITECTURE.md -- Independent package testing workflow +**Implements architecture:** Foundation → Core layer in dependency DAG -**Avoids:** -- Pitfall #3 (import leakage) via isolated testing from day 1 -- Pitfall #14 (src layout confusion) via clear documentation +**Avoids pitfalls:** +- P2 (Manager().dict() spawn) — CachedOmeZarrDataModule addressed in this phase +- P11 (MRO fragility) — copy-first, no refactoring during extraction -### Phase 3: Code and Test Migration -**Rationale:** Moves actual code after scaffolding is validated. Separating this from Phase 2 allows validation of structure before content. +### Phase 3: Specialized Data Modules +**Rationale:** Migrate pipeline-specific DataModules that extend core classes. These introduce optional dependencies and lazy loading patterns. **Delivers:** -- Migrated code: `viscy/transforms/*.py` → `packages/viscy-transforms/src/viscy_transforms/` -- Updated imports within package -- Migrated tests: `tests/transforms/` → `packages/viscy-transforms/tests/` -- Updated test imports +- `triplet.py` (TripletDataset, TripletDataModule) — add lazy imports for tensorstore/pandas +- `cell_classification.py` (ClassificationDataset, ClassificationDataModule) — lazy pandas import +- `cell_division_triplet.py` (CellDivisionTripletDataset, CellDivisionTripletDataModule) +- `mmap_cache.py` (MmappedDataset, MmappedDataModule) — lazy tensordict import +- `livecell.py` (LiveCellDataset, LiveCellTestDataset, LiveCellDataModule) — lazy pycocotools/tifffile imports +- `ctmc_v1.py` (CTMCv1DataModule) +- `segmentation.py` (SegmentationDataset, SegmentationDataModule) + +**Uses stack:** tensorstore, tensordict, pycocotools (all optional) -**Addresses:** -- Test organization (table stakes) -- Clean import paths requirement +**Implements architecture:** Specialized modules layer in DAG -**Avoids:** -- Pitfall #5 (entry points lost) by auditing and testing CLI -- Pitfall #2 (dependency conflicts) via careful dependency specification +**Avoids pitfalls:** +- P1 (lazy imports) — centralized pattern for all optional deps +- P7 (ThreadDataLoader leaks) — addressed in triplet.py migration +- P12 (MemoryMappedTensor cleanup) — addressed in mmap_cache.py -### Phase 4: CI/CD Updates -**Rationale:** CI must validate monorepo structure before merging. Comes after code migration so there's something to test. +### Phase 4: Composition Modules & Finalize +**Rationale:** Migrate the high-level composition wrappers that depend on core modules, then finalize the package with complete exports and README. **Delivers:** -- GitHub Actions workflows for monorepo testing -- Package-specific test jobs with path-based filtering -- Build verification (version correctness) -- Independent package testing validation +- `combined.py` (CombinedDataModule, CombineMode) — update imports +- `concat.py` (ConcatDataModule, BatchedConcatDataModule, CachedConcatDataModule, BatchedConcatDataset) — split from combined.py +- Complete `__init__.py` with all public exports (15 classes + 8 types) +- Package README adapted from `viscy/data/README.md` -**Addresses:** -- CI changed-package filtering (table stakes) -- Path-based filtering requirement -- Build caching for efficiency +**Implements architecture:** Composition layer, public API surface -**Avoids:** -- Pitfall #11 (CI cache explosion) via `uv cache prune --ci` -- Pitfall #3 (import leakage) by testing packages in isolation +**Avoids pitfalls:** +- P8 (__init__.py eager imports) — only re-export modules with required deps -### Phase 5: Documentation Migration -**Rationale:** Documentation can be migrated after core functionality works. Zensical setup is independent of code migration. +### Phase 5: Test Migration & CI +**Rationale:** Migrate existing tests after code modules are stable, establish test fixtures with proper cleanup, configure tiered CI matrix. **Delivers:** -- Zensical configuration replacing current docs -- Per-package documentation structure -- API documentation from docstrings (mkdocstrings) -- GitHub Pages deployment workflow - -**Uses:** -- Zensical (successor to Material for MkDocs) -- mkdocstrings-python for API doc generation +- `tests/conftest.py` with session-scoped OME-Zarr fixtures (migrate from main branch tests/conftest.py) +- `test_hcs.py` (update imports, verify HCSDataModule + SlidingWindowDataset) +- `test_triplet.py` (update imports, add ThreadDataLoader cleanup) +- `test_select.py` (update imports, verify SelectWell mixin) +- `test_typing.py` (new: smoke tests for type definitions) +- CI workflow with tiered matrix: base deps (3x3), full extras (1x1), per-extra smoke tests -**Addresses:** -- API documentation generation (differentiator) -- Package-specific documentation +**Verifies:** All table-stakes features work, pitfall mitigations are effective -**Avoids:** -- Pitfall #12 (Jekyll interference) via `.nojekyll` file in deploy workflow +**Avoids pitfalls:** +- P4 (CI matrix explosion) — tiered strategy keeps job count manageable +- P9 (expensive fixtures) — session-scoped, read-only fixtures +- P7 (ThreadDataLoader leaks) — explicit cleanup in fixtures +- P12 (mmap cleanup) — explicit teardown for MemoryMappedTensor -### Phase 6: Validation and Documentation (Launch) -**Rationale:** Final validation before considering MVP complete. Documentation ensures future maintainers understand the patterns. +### Phase 6: Workspace Integration & Validation +**Rationale:** Verify the extracted package integrates correctly with the workspace and existing configs still reference correct import paths. **Delivers:** -- Developer guide for monorepo workflow -- Migration guide for downstream users -- Example updates (fix broken imports in examples/) -- Version validation and test coverage verification +- Root `pyproject.toml` verified with viscy-data in dependencies and [tool.uv.sources] +- All YAML/JSON configs in applications/ checked for stale `viscy.data.` references +- Integration test: `uv sync --package viscy-data` + `uv run --package viscy-data pytest` +- Integration test: viscy meta-package can import from both viscy-transforms and viscy-data +- Documentation: migration guide with old → new import paths -**Addresses:** -- Clean break import migration (VisCy-specific risk #3) -- Documentation of migration path +**Verifies:** Clean workspace integration, no config breakage -### Phase Ordering Rationale +**Avoids pitfalls:** +- P10 (config class_path breakage) — grep + update all in-repo configs +- P6 (iohub API coupling) — integration test verifies iohub types -- **Foundation first (Phase 1):** Workspace configuration is prerequisite for all packages; Python version floor prevents rework -- **Pattern establishment (Phase 2-3):** First extraction creates blueprint for future packages; validating structure before content prevents large-scale rework -- **Validation early (Phase 4):** CI must validate monorepo before considering it functional; testing in isolation catches import leakage -- **Documentation deferred (Phase 5):** Zensical setup independent of code migration; can proceed in parallel with Phase 4 if resources allow -- **Launch preparation (Phase 6):** User-facing docs and examples updated after core functionality proven +### Phase Ordering Rationale -**Dependency ordering:** -- Phase 1 blocks all others (foundation) -- Phase 2 blocks Phase 3 (scaffolding before content) -- Phase 3 blocks Phase 4 (must have code to test) -- Phase 4 and Phase 5 can run in parallel after Phase 3 -- Phase 6 depends on all previous phases - -**Avoids pitfalls:** -- Phase-gated extraction prevents commitment to flawed structure -- Isolation testing at each phase catches import leakage early -- Build verification before merge prevents version issues in production +- **Sequential dependency chain:** Foundation → Core → Specialized → Composition follows the import DAG. Each phase depends on the previous phase being complete. +- **Extract _utils.py FIRST:** This is the critical prerequisite. The current hcs.py dual-role creates coupling that blocks clean extraction of downstream modules. +- **Lazy imports in Specialized phase:** Optional dependencies are leaf nodes in the dependency graph. They're isolated in Phase 3 so Phase 2 can be tested without tensorstore/tensordict/pycocotools. +- **Tests after code:** Tests require all modules to exist. Session-scoped fixtures need the full package structure. Testing comes after Phases 1-4 are stable. +- **CI after tests:** The tiered CI matrix needs to know which tests can run with base deps vs. which need extras. CI design happens after test structure is known. ### Research Flags -**Phases needing deeper research during planning:** -- **Phase 2:** hatch-vcs tag pattern configuration (new as of v1.0.1, Jan 2026) — verify pattern syntax for monorepo -- **Phase 4:** GitHub Actions workspace testing patterns — sparse official guidance on monorepo path filtering -- **Phase 5:** Zensical migration from mkdocs.yml (Alpha software, v0.0.19) — may need fallback plan to mkdocs-material - **Phases with standard patterns (skip research-phase):** -- **Phase 1:** Workspace scaffolding — well-documented in uv official docs -- **Phase 3:** Code migration — standard Python refactoring patterns -- **Phase 6:** Documentation — standard technical writing +- **Phase 1-4:** Code extraction follows the proven viscy-transforms pattern. All architectural decisions are documented in existing research. +- **Phase 5:** Test fixture patterns are well-documented in existing tests/conftest.py. CI workflow structure mirrors existing test.yml. +- **Phase 6:** Workspace integration is standard uv workspace mechanics. + +**No phases need additional research.** All architectural decisions, dependency choices, and pitfall mitigations are informed by the comprehensive upfront research (STACK.md, FEATURES.md, ARCHITECTURE.md, PITFALLS.md) and the established viscy-transforms precedent. ## Confidence Assessment | Area | Confidence | Notes | |------|------------|-------| -| Stack | HIGH | Verified with official uv, hatchling, hatch-vcs docs; multiple successful deployments (pydantic-ai, MCP SDK) | -| Features | HIGH | Based on uv official workspace docs and PEP 735; table stakes well-established in community | -| Architecture | HIGH | Patterns verified in official uv documentation; src layout is pytest/pip best practice | -| Pitfalls | MEDIUM-HIGH | Critical pitfalls verified in official docs; moderate/minor based on GitHub issues and community reports | +| Stack | HIGH | Core dependencies verified via lockfile and source code analysis. Optional dependencies verified via original pyproject.toml. Python version support follows workspace standard. | +| Features | HIGH | All 13 modules analyzed with direct source code review. Import paths, class hierarchies, and dependency graph documented in existing `viscy/data/README.md`. Feature requirements are table-stakes extraction, not new development. | +| Architecture | HIGH | Package layout follows proven viscy-transforms pattern. Internal dependency graph is well-documented (README.md). Shared utilities extraction is the only new architectural element, and it's a straightforward refactoring. | +| Pitfalls | MEDIUM-HIGH | Pitfalls derived from: (1) codebase analysis, (2) v1.0 extraction experience, (3) domain expertise with PyTorch multiprocessing, Lightning DataModules, tensorstore, and C-extension packages. WebSearch unavailable during research, so some cross-platform build claims (tensorstore arm64, pycocotools Windows wheels) could not be verified against current package indices. | **Overall confidence:** HIGH -Research is comprehensive with strong official documentation coverage. Lower confidence areas (Zensical, hatch-cada) have fallback options (mkdocs-material 9.7.0, uv-dynamic-versioning respectively) and don't block core functionality. +The extraction is architecturally straightforward and follows established patterns. The three complexities (heavy I/O deps, optional deps, cross-package dependency) are well-understood and have documented mitigation strategies. The main uncertainties are platform-specific (tensorstore/pycocotools wheel availability), which are addressed by making those dependencies optional and testing in a tiered CI matrix. ### Gaps to Address -**Gap: Zensical Alpha stability** -- **Impact:** Documentation generation may have bugs -- **Handling:** Keep mkdocs-material 9.7.0 as fallback; Zensical maintains compatibility with mkdocs.yml config -- **Validation:** Test Zensical during Phase 5 before committing; easy to roll back - -**Gap: IDE workspace support** -- **Impact:** VS Code/PyCharm may not understand workspace structure; import errors shown for valid code -- **Handling:** Configure `.vscode/settings.json` with Python paths; use `uv sync` to populate `.venv`; document in developer guide -- **Validation:** Test with both VS Code and PyCharm during Phase 1 +**Platform-specific dependency availability:** +- **tensorstore Python 3.13 support:** Wheels may not exist yet. Mitigated by making `[triplet]` optional and testing extras only on Python 3.11-3.12 in CI. +- **pycocotools Windows build:** No pre-built wheels for some Python versions. Mitigated by excluding Windows from livecell tests in CI or documenting as Linux/macOS only. +- **tensordict Python 3.13 support:** Same mitigation as tensorstore (optional, narrower CI matrix). -**Gap: PyTorch + NumPy version matrix** -- **Impact:** NumPy 2.0 migration ongoing; PyTorch has tight NumPy requirements; potential dependency conflicts -- **Handling:** Pin NumPy range compatible with PyTorch 2.4+; test against both NumPy 1.x and 2.x in CI matrix -- **Validation:** Run `uv tree` during Phase 2 to inspect resolved versions; monitor NumPy 2.0 ecosystem compatibility +**iohub version stability:** +- iohub is pinned at pre-release (0.3a2) because stable release timeline is unknown. The API is stable in VisCy production use, but future releases may have breaking changes. Mitigated by floor pin (`>=0.3a2`), no upper bound, and integration test that verifies expected types/attributes. -**Gap: Docker build efficiency** -- **Impact:** Docker builds may copy entire workspace for every package; massive cache invalidation -- **Handling:** Defer to post-MVP; use `uv sync --frozen --package ` when available; structure Dockerfiles for minimal layer invalidation -- **Validation:** Measure Docker build times in CI during Phase 4; optimize if blocking +**Manager().dict() cross-platform:** +- Shared cache pattern works on Linux (fork) but needs testing on macOS/Windows (spawn). Mitigated by explicit spawn testing in CI. If failures persist, fallback is to document CachedOmeZarrDataModule as Linux-only or refactor to file-based cache (tensordict MemoryMappedTensor pattern already exists in mmap_cache.py). -**Gap: Release automation** -- **Impact:** Manual release process initially; potential for version tag errors -- **Handling:** Document manual release workflow clearly; consider python-semantic-release post-MVP -- **Validation:** Test manual release workflow during Phase 6 with test PyPI +None of these gaps block the extraction. All have documented mitigation strategies that can be applied during Phase 2 (Manager().dict()), Phase 3 (optional deps), and Phase 5 (CI matrix). ## Sources ### Primary (HIGH confidence) -- [uv Workspaces Documentation](https://docs.astral.sh/uv/concepts/projects/workspaces/) — Workspace configuration, member discovery, inter-package dependencies -- [uv Project Dependencies](https://docs.astral.sh/uv/concepts/projects/dependencies/) — Dependency groups (PEP 735), workspace sources -- [Hatchling Build Configuration](https://hatch.pypa.io/latest/config/build/) — Build backend, src layout, packages -- [PEP 735 - Dependency Groups](https://peps.python.org/pep-0735/) — dependency-groups specification -- [hatch-vcs PyPI](https://pypi.org/project/hatch-vcs/) — Git-based versioning for hatchling -- [hatch-cada GitHub](https://github.com/bilelomrani1/hatch-cada) — Workspace dependency rewriting at build time -- [Zensical Documentation](https://zensical.org/docs/get-started/) — MkDocs successor, setup and migration -- [pytest Good Integration Practices](https://docs.pytest.org/en/stable/explanation/goodpractices.html) — src layout, test organization - -### Secondary (MEDIUM confidence) -- [Python Workspaces (Monorepos) - tomasrepcik.dev](https://tomasrepcik.dev/blog/2025/2025-10-26-python-workspaces/) — Real-world workspace structure patterns -- [uv Monorepo Best Practices Issue #10960](https://github.com/astral-sh/uv/issues/10960) — Community discussion on workspace patterns -- [LlamaIndex Monorepo Overhaul](https://www.llamaindex.ai/blog/python-tooling-at-scale-llamaindex-s-monorepo-overhaul) — Large-scale Python monorepo migration case study -- [Dynamic Versioning and Automated Releases](https://slhck.info/software/2025/10/01/dynamic-versioning-uv-projects.html) — uv-dynamic-versioning practical guide -- [Tweag Python Monorepo Guide](https://www.tweag.io/blog/2023-04-04-python-monorepo-1/) — Architectural patterns for Python monorepos -- [FOSDEM 2026 - Modern Python monorepo with uv](https://fosdem.org/2026/schedule/event/WE7NHM-modern-python-monorepo-apache-airflow/) — Apache Airflow's uv workspace migration - -### Tertiary (LOW confidence, needs validation) -- [uv Issue #6935 - Workspaces and monorepo support](https://github.com/astral-sh/uv/issues/6935) — Docker build efficiency in workspaces -- [uv Issue #2231 - CI cache management](https://github.com/astral-sh/uv/issues/2231) — Cache pruning strategies -- [NumPy 2.0 Ecosystem Compatibility #26191](https://github.com/numpy/numpy/issues/26191) — NumPy version matrix tracking +- `viscy/data/README.md` (modular-data branch) — Comprehensive module inventory, dependency graph, class hierarchy, GPU transform patterns +- All 13 source files in `viscy/data/` on main branch — Direct import statement analysis, function-level dependency tracing +- `packages/viscy-transforms/` — Established extraction pattern (pyproject.toml, __init__.py, _typing.py, CI structure) +- `main:pyproject.toml` — Original dependency pins: iohub>=0.3a2, monai>=1.4, lightning>=2.3 +- `uv.lock` — Resolved versions: monai 1.5.2, torch 2.10.0, numpy 2.4.2, tifffile 2026.1.28 +- `.planning/PROJECT.md` — Project constraints (no viscy-transforms dependency, clean break imports, optional extras) +- `.planning/ROADMAP.md` — Milestone 1 completion status, workspace patterns + +### Secondary (HIGH confidence) +- `main:tests/conftest.py` — Test fixture patterns for HCS OME-Zarr stores, tracks datasets +- `main:tests/data/test_hcs.py`, `test_select.py`, `test_triplet.py` — Existing test coverage and patterns +- MONAI `monai.data.__init__.py` — Flat API export pattern (100+ symbols from 20+ modules) +- viscy-transforms `__init__.py` — Sibling package pattern (44 exports, underscore-prefixed private modules) + +### Tertiary (MEDIUM confidence, needs validation) +- tensorstore Python 3.13 wheel availability — Claimed LIMITED based on historical lag, but not verified against current PyPI +- tensordict Python 3.13 wheel availability — Claimed LIMITED, same reason +- pycocotools Windows wheel coverage — Claimed REQUIRES C COMPILER for missing wheels, based on common CI failure pattern +- iohub latest stable release status — Pre-release 0.3a2 is used;

However, nearly ALL modules (including core modules like hcs.py) import `iohub.ngff` eagerly at the module level, and iohub has transitive dependencies on pandas/xarray/dask. This means: + +1. `import viscy_data` → `from viscy_data.hcs import ...` → executes hcs.py → `from iohub.ngff import ...` → fails without pandas +2. The ImportError guards in class `__init__` methods (e.g., `TripletDataset.__init__`) are never reached because the module import fails first +3. Even "core" modules (hcs, gpu_aug, segmentation) that don't need optional extras for their basic functionality cannot be imported without pandas installed + +**Fix required:** Either: +- Option A: Make __init__.py use lazy imports (TYPE_CHECKING pattern or `__getattr__` pattern) +- Option B: Make iohub imports lazy (move inside methods, or add try/except with None sentinel at module level) +- Option C: Declare iohub/pandas as a base dependency (not optional), which defeats the purpose of optional extras + +**Recommendation:** Option B (lazy iohub imports) is most aligned with the phase goal. Move iohub imports inside methods/functions or use try/except at module level. + +--- + +_Verified: 2026-02-13T18:30:00Z_ +_Verifier: Claude (gsd-verifier)_ From 02a219ee72172524594094453d89e139154ae748 Mon Sep 17 00:00:00 2001 From: Alexandr Kalinin Date: Fri, 13 Feb 2026 17:26:09 -0800 Subject: [PATCH 077/240] docs(08-test-migration-and-validation): create phase plan --- .planning/ROADMAP.md | 6 +- .../08-01-PLAN.md | 184 ++++++++++++++++++ .../08-02-PLAN.md | 123 ++++++++++++ 3 files changed, 310 insertions(+), 3 deletions(-) create mode 100644 .planning/phases/08-test-migration-and-validation/08-01-PLAN.md create mode 100644 .planning/phases/08-test-migration-and-validation/08-02-PLAN.md diff --git a/.planning/ROADMAP.md b/.planning/ROADMAP.md index 87ef1aec4..c36b8580d 100644 --- a/.planning/ROADMAP.md +++ b/.planning/ROADMAP.md @@ -137,11 +137,11 @@ Plans: 1. `uv run --package viscy-data pytest` passes all tests (test_hcs.py, test_triplet.py, test_select.py) 2.

But keep the assertions clearly separated with descriptive comments for each requirement (INFER-02 section, INFER-03 section). +- Alternatively, use pytest fixtures with `scope="module"` to cache the prediction output path. +- Use `lightning.seed_everything(42)` to match the original config's `seed_everything: 42`. +- Use `precision="32-true"` to match original config. +- Use `inference_mode=True` in the Trainer to match original. +- Note: The TripletDataModule uses `collate_fn=lambda x: x` which produces list-of-dicts batches. The predict_step in ContrastiveModule handles `batch["anchor"]` which works because MONAI's ThreadDataLoader with this collate_fn stacks the samples automatically. This is an existing pattern that works. + + + - If on HPC with GPU: `uv run --package dynacrl pytest applications/dynacrl/tests/test_inference_reproducibility.py -v` — all tests pass + - If NOT on HPC or no GPU: `uv run --package dynacrl pytest applications/dynacrl/tests/test_inference_reproducibility.py -v` — all tests are SKIPPED with clear reason + - Full suite: `uv run --package dynacrl pytest -v` — all tests pass (6 existing + 2-3 new, with HPC tests either passing or skipping) + + + - test_checkpoint_loads_into_modular_contrastive_module passes (INFER-01) + - test_predict_embeddings_and_exact_match passes: writes zarr AND matches reference (INFER-02 + INFER-03) + - All tests live in applications/dynacrl/tests/ (TEST-01) + - Full suite runs via `uv run --package dynacrl pytest` (TEST-02) + - Tests skip gracefully when HPC paths or GPU unavailable + + + + + + +1.

MultiExperimentIndex builds a single tracks DataFrame from all registered experiments with columns: experiment, condition, global_track_id, hours_post_infection, well_name, fluorescence_channel -- and each row represents one cell observation at one timepoint + 2. Lineage is reconstructed from parent_track_id -- when a cell divides, daughter tracks are linked to the parent track so that temporal positive sampling can follow through division events + 3. Border cells are retained by clamping crop centroids inward rather than excluding them -- cells near the image boundary still appear as valid observations with shifted patch origins + 4. valid_anchors is computed accounting for variable tau range and lineage continuity -- an anchor is valid only if at least one tau in the configured range yields a same-track or daughter-track positive +**Plans**: TBD +**Location**: `applications/dynaclr/src/dynaclr/` + +### Phase 22: Batch Sampling +**Goal**: Users can compose experiment-aware, condition-balanced, and temporally enriched batch sampling strategies via a single configurable FlexibleBatchSampler +**Depends on**: Phase 21 (MultiExperimentIndex provides valid_anchors DataFrame) +**Requirements**: SAMP-01, SAMP-02, SAMP-03, SAMP-04, SAMP-05 +**Success Criteria** (what must be TRUE): + 1. With experiment_aware=True, every batch contains cells from only a single experiment (verified over many batches) + 2. With condition_balanced=True, each batch has approximately 50/50 infected vs uninfected cells (within statistical tolerance across many batches) + 3. With temporal_enrichment=True, batches concentrate cells around a focal HPI with a configurable window, while still including a global fraction from all timepoints + 4. FlexibleBatchSampler supports DDP via set_epoch() for deterministic shuffling and rank-aware iteration that composes with the existing ShardedDistributedSampler pattern + 5.

NTXentHCL computes NT-Xent loss with hard-negative concentration (beta parameter), returns a scalar loss with gradients, and produces numerically identical results to standard NT-Xent when beta=0.0 + 2. NTXentHCL is an nn.Module that works as a drop-in replacement via ContrastiveModule(loss_function=NTXentHCL(...)) without any changes to the training step + 3. ChannelDropout randomly zeros specified channels with configurable probability on batched (B,C,Z,Y,X) tensors and integrates into on_after_batch_transfer after the existing scatter/gather augmentation chain + 4.

MultiExperimentTripletDataset.__getitems__ returns a batch dict with anchor, positive keys and norm_meta that is directly compatible with the existing ContrastiveModule.training_step -- no changes to the engine + 2.

Accomplishments +- MultiExperimentIndex builds flat tracks DataFrame from all experiments in ExperimentRegistry with enriched columns: experiment, condition, global_track_id, hours_post_infection, fluorescence_channel, well_name, fov_name, position, lineage_id, y_clamp, x_clamp +- Lineage reconstruction: parent_track_id graph traversal per experiment+fov propagates root ancestor's global_track_id as lineage_id to all descendants (daughters, granddaughters, etc.) +- Border clamping: cells near edges get clipped centroids (y_clamp, x_clamp) instead of being excluded; only cells completely outside image boundary are removed +- 23 passing tests covering CELL-01 (unified tracks, 12 tests), CELL-02 (lineage, 5 tests), CELL-03 (border clamping, 6 tests) + +## Task Commits + +Each

index.py with MultiExperimentIndex, all 23 tests pass +3. **REFACTOR: Cleanup** - `98dc7a6` (refactor) - Fix ruff lint issues (unused variable F841, .values->to_numpy PD011), export from __init__.py + +## Files Created/Modified +- `applications/dynaclr/src/dynaclr/index.py` - MultiExperimentIndex class with tracks loading, lineage reconstruction, border clamping (238 lines) +-

+## Decisions Made +- Border clamping retains all cells within image bounds (y >= 0, y < height, x >= 0, x < width); only cells with centroid completely outside image are excluded -- this maximizes training data vs. the old TripletDataset._filter_tracks exclusion approach +- Lineage reconstruction chases parent_track_id to root ancestor; tracks whose parent_track_id references a track not in the data gracefully fall back to their own global_track_id as lineage_id +- iohub Position objects stored directly in DataFrame column for downstream data loading -- avoids separate lookup table +- Image dimensions (height, width) read from position["0"] (ImageArray attributes) during loading, used for clamping, then dropped as internal columns + +## Deviations from Plan + +None - plan executed exactly as written. + +## Issues Encountered +None. + +## User Setup Required +None - no external service configuration required. + +## Next Phase Readiness +- MultiExperimentIndex ready for

From: Eduardo Hirata-Miyasaki Date: Sat, 21 Feb 2026 22:43:14 -0800 Subject: [PATCH 136/240] test(21-02): add failing tests for valid anchors, properties, and summary - 8 tests for valid_anchors: basic validity, subset check, end-of-track exclusion, lineage continuity, different tau ranges, empty tracks, gap handling, self-exclusion - 9 tests for properties/summary: experiment_groups,

It operates on the `valid_anchors` DataFrame produced by Phase 21's `MultiExperimentIndex` and yields lists of integer indices consumed by `__getitems__()` in the downstream dataset (Phase 24). The sampler lives in `packages/viscy-data/src/viscy_data/` as a reusable utility. + +The core challenge is composing three independent sampling axes -- experiment restriction, condition balancing, and temporal enrichment -- into a single `__iter__` method that yields batch-sized index lists. Each axis progressively narrows the candidate pool for a batch. DDP support requires `set_epoch()` for deterministic shuffling and rank-aware index partitioning that composes with the existing `ShardedDistributedSampler` pattern. + +This is a well-understood problem domain. PyTorch's `Sampler[list[int]]` protocol is simple (`__iter__` yielding `list[int]`, `__len__`), and the `batch_sampler=` kwarg to `DataLoader`/`ThreadDataLoader` handles integration. The main complexity is the sampling logic itself: picking experiments, balancing conditions within experiments, and concentrating around temporal windows -- all while maintaining deterministic behavior across DDP ranks. + +**Primary recommendation:** Implement `FlexibleBatchSampler` as a `Sampler[list[int]]` subclass using a cascade approach: (1) pick experiment, (2) filter by condition quotas, (3) filter by temporal window, (4) sample indices. Use numpy RNG seeded by `epoch + seed` for DDP determinism.

This is simpler than trying to partition indices across ranks before batch construction, which would break experiment-aware constraints. + +### Pattern 3: Pre-computed Group Indices + +**What:** At `__init__` time, pre-compute per-experiment and per-condition index arrays from the valid_anchors DataFrame. Avoid repeated groupby during iteration. +**When to use:** Always. The valid_anchors DataFrame is immutable between epochs. + +```python +# Source: MultiExperimentIndex already provides experiment_groups and +# condition_groups, but FlexibleBatchSampler operates on valid_anchors +# (which has its own index space after reset_index(drop=True)) + +def _precompute_groups(self): + """Build lookup tables from valid_anchors columns.""" + self._experiment_indices = {} + for exp_name, group in self.valid_anchors.groupby("experiment"): + self._experiment_indices[exp_name] = group.index.to_numpy() + + self._condition_indices = {} + for cond, group in self.valid_anchors.groupby("condition"): + self._condition_indices[cond] = group.index.to_numpy() + + # Cross-index: per-experiment, per-condition + self._exp_cond_indices = {} + for (exp, cond), group in self.valid_anchors.groupby(["experiment", "condition"]): + self._exp_cond_indices[(exp, cond)] = group.index.to_numpy() +``` + +### Pattern 4: Temporal Enrichment with Focal Window + +**What:** Concentrate a fraction of the batch around a focal HPI, with the rest drawn globally. +**When to use:** When `temporal_enrichment=True`. + +```python +# Source: CONCORD (Zhu et al. Nature Biotech 2026) temporal concentration strategy + +def _enrich_temporal(self, pool: np.ndarray, rng: np.random.Generator) -> np.ndarray: + """Concentrate pool around a randomly chosen focal HPI.""" + hpi_values = self.valid_anchors.loc[pool, "hours_post_infection"].values + + # Pick focal HPI from existing values + focal_hpi = rng.choice(np.unique(hpi_values)) + + # Split pool into focal window and global + in_window = np.abs(hpi_values - focal_hpi) <= self.temporal_window_hours + focal_pool = pool[in_window] + global_pool = pool[~in_window] + + # Determine counts + n_global = int(self.batch_size * self.temporal_global_fraction) + n_focal = self.batch_size - n_global + + # Sample from each + focal_samples = rng.choice(focal_pool, size=min(n_focal, len(focal_pool)), replace=len(focal_pool) < n_focal) + global_samples = rng.choice(global_pool, size=min(n_global, len(global_pool)), replace=len(global_pool) < n_global) + + return np.concatenate([focal_samples, global_samples]) +``` + +### Anti-Patterns to Avoid + +- **Modifying valid_anchors during iteration:** The DataFrame is shared state. Never mutate it. All filtering should use boolean masks or index arrays. +- **Using pandas operations in the hot loop:** `groupby` and `loc` in `__iter__` are slow. Pre-compute index arrays at `__init__` time. +- **Global numpy random state:** PML samplers use `np.random.shuffle()` (global state) which is not DDP-safe. Always use `np.random.Generator` with explicit seed. +- **Coupling sampler to dataset:** The sampler should only know about index metadata (experiment, condition, HPI), never about image data or Position objects. +- **Trying to use batch_sampler AND sampler simultaneously:** PyTorch DataLoader raises ValueError if both are specified. When using `batch_sampler=`, do NOT pass `batch_size`, `shuffle`, `sampler`, or `drop_last`. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| DDP index partitioning | Custom shard logic | Interleaved batch assignment (rank slicing) | Edge cases with uneven batches, padding, drop_last | +| Seeded RNG | `random.seed()` / `np.random.seed()` | `np.random.default_rng(seed)` | Thread-safe, no global state pollution, DDP-compatible | +| Weighted random selection | Manual probability computation | `rng.choice(a, p=weights)` | NumPy handles normalization, edge cases | +| DataFrame group indices | Repeated `df[df["col"]==val].index` | Pre-computed dict from `groupby` at init | O(1) lookup vs O(n) scan per batch | + +**Key insight:** The sampling logic itself is custom (no library provides this exact 3-axis composition), but all the building blocks (seeded RNG, weighted choice, index arrays) are standard numpy operations. The only truly custom code is the cascade logic in `_build_one_batch`. + +## Common Pitfalls + +### Pitfall 1: Non-deterministic DDP batches +**What goes wrong:** Different ranks generate different batches, leading to gradient desync and training divergence. +**Why it happens:** RNG not seeded identically across ranks, or `set_epoch()` not called. +**How to avoid:** Use `seed + epoch` as RNG seed. All ranks generate the same full batch list, then each takes its interleaved slice. Verify with a test that checks `set_epoch(0)` on rank 0 and rank 1 produce disjoint but collectively exhaustive batches. +**Warning signs:** NaN losses, validation metrics diverge between ranks, training hangs at gradient sync. + +### Pitfall 2: Small experiment/condition groups cause replacement sampling +**What goes wrong:** An experiment or condition has fewer cells than `batch_size`, requiring sampling with replacement, which duplicates samples. +**Why it happens:** Unbalanced datasets (e.g., 20 infected cells but batch_size=128). +**How to avoid:** Document the constraint: `batch_size` should not exceed the smallest experiment-condition group. Add a warning in `__init__` if any group is smaller than batch_size. Fall back to replacement sampling with a logged warning rather than crashing. +**Warning signs:** Training loss plateaus early, effective batch diversity is low. + +### Pitfall 3: Temporal enrichment starves rare timepoints +**What goes wrong:** With a narrow temporal window, cells at the edges of the HPI range are never sampled as focal cells, and the global fraction is too small to include them. +**Why it happens:** `temporal_window_hours` is too narrow, or `temporal_global_fraction` is too low. +**How to avoid:** Default `temporal_global_fraction=0.3` ensures 30% of each batch comes from all timepoints. Focal HPI is chosen uniformly from available HPIs, not weighted. +**Warning signs:** Embeddings cluster only by time, not by biological state. + +### Pitfall 4: batch_sampler + ThreadDataLoader kwargs conflict +**What goes wrong:** Passing `batch_sampler=` along with `batch_size=`, `shuffle=`, or `drop_last=` to DataLoader raises ValueError. +**Why it happens:** PyTorch enforces mutual exclusivity between `batch_sampler` and these kwargs. +**How to avoid:** When using FlexibleBatchSampler, the DataModule (Phase 24) must NOT pass batch_size/shuffle/drop_last to ThreadDataLoader. Only pass `batch_sampler=`, `num_workers=`, `collate_fn=`, etc. +**Warning signs:** ValueError at DataLoader construction time (easy to catch in tests). + +### Pitfall 5: __len__ mismatch with actual iteration count +**What goes wrong:** DataLoader expects `__len__` to return the correct number of batches for progress bars and epoch completion. If `__len__` disagrees with actual `__iter__` count, training loop may hang or skip data. +**Why it happens:** `__len__` computed from total indices / batch_size, but actual batches depend on per-experiment constraints that may yield fewer batches. +**How to avoid:** Compute `__len__` as `total_batches // num_replicas` where `total_batches` is the number of batches that `__iter__` will actually yield. Pre-compute this in `__init__` based on the total number of valid anchors and batch size. +**Warning signs:** Progress bar stuck at 99%, training epoch never completes, or ends prematurely. + +### Pitfall 6: valid_anchors index vs tracks index confusion +**What goes wrong:** valid_anchors has `reset_index(drop=True)`, giving it indices 0..N-1. The sampler yields these indices. But if someone confuses them with tracks indices (which may be a superset), wrong cells get loaded. +**Why it happens:** Two DataFrames (tracks, valid_anchors) with different index spaces. +**How to avoid:** The sampler operates ONLY on valid_anchors indices. Document this clearly. The dataset's `__getitems__` also uses `self.valid_anchors.iloc[indices]`, matching the sampler's output. +**Warning signs:** KeyError or IndexError when dataset tries to look up a sampler-provided index. + +## Code Examples + +### FlexibleBatchSampler skeleton (verified pattern from PyTorch Sampler protocol) + +```python +# Source: torch.utils.data.sampler.Sampler protocol + DistributedSampler pattern +from __future__ import annotations + +import math +from collections.abc import Iterator + +import numpy as np +import pandas as pd +from torch.utils.data import Sampler + + +class FlexibleBatchSampler(Sampler[list[int]]): + """Composable batch sampler with experiment-aware, condition-balanced, + and temporal enrichment axes. + + Yields lists of integer indices into a valid_anchors DataFrame. + """ + + def __init__( + self, + valid_anchors: pd.DataFrame, + batch_size: int = 128, + #

Avoid. + +## Open Questions + +1. **Experiment weighting strategy** + - What we know: `experiment_weights` allows manual per-experiment probabilities for experiment selection. + - What's unclear: Should the default be uniform across experiments, or proportional to the number of valid anchors per experiment? + - Recommendation: Default to proportional (larger experiments sampled more often) with uniform as an explicit option. This prevents tiny experiments from dominating batch counts. Planner can decide. + +2. **Condition ratio when more than 2 conditions exist** + - What we know: Current requirements assume binary (infected/uninfected). `condition_ratio` dict supports N conditions. + - What's unclear: What if an experiment has 3+ conditions (e.g., "uninfected", "low_moi", "high_moi")? + - Recommendation: Support arbitrary condition counts. Default to equal ratios. The `condition_ratio` dict allows user override. + +3. **Temporal enrichment focal HPI selection** + - What we know: A focal HPI is chosen per batch, and cells within `temporal_window_hours` are concentrated. + - What's unclear: Should focal HPI be chosen from the union of all HPIs in the experiment, or per-batch randomly? + - Recommendation: Per-batch random selection from unique HPIs within the chosen experiment. This ensures all timepoints get exposure across batches. + +4. **How `__len__` interacts with Lightning's progress bar** + - What we know: Lightning calls `len(dataloader)` for progress bars. DataLoader delegates to `len(batch_sampler)`. + - What's unclear: If the sampler's actual iteration count varies slightly from `__len__` (due to rounding in condition balance), does Lightning handle this gracefully? + - Recommendation: Make `__len__` a conservative lower bound (floor division). Lightning handles `__iter__` exhaustion gracefully. + +5. **Interaction with `ShardedDistributedSampler` vs embedded DDP** + - What we know: STATE.md says "DDP via FlexibleBatchSampler + ShardedDistributedSampler composition". But `batch_sampler=` and `sampler=` are mutually exclusive in DataLoader. + - What's unclear: Does "composition" mean embedding DDP logic inside FlexibleBatchSampler, or wrapping? + - Recommendation: Embed DDP logic directly in FlexibleBatchSampler (num_replicas, rank, set_epoch). Do NOT try to compose with ShardedDistributedSampler as a separate sampler -- DataLoader forbids this. The "composition" means FlexibleBatchSampler follows the same pattern (set_epoch, rank-aware slicing) rather than literally wrapping ShardedDistributedSampler. + +## Upstream Dependencies (Phase 21 API Surface) + +### valid_anchors DataFrame Schema + +The FlexibleBatchSampler receives `valid_anchors` which is a `pd.DataFrame` with `reset_index(drop=True)` (integer index 0..N-1).

A genuine gap -- something should have been wired in Phase 23 (e.g., into TripletDataModule.on_after_batch_transfer as a proof of integration). + +Given the ROADMAP language and Phase 24's explicit responsibility for wiring, this is likely interpretation (1).

The engine only reads `batch["anchor"]` and `batch["positive"]`, so the batch format is fully compatible without engine changes. + +2. **Division lineage:** `_reconstruct_lineage` in `index.py` sets each track's `lineage_id` to its root ancestor's `global_track_id` via parent graph traversal. Daughters share the parent's `lineage_id`. The dataset's `_build_lineage_lookup` indexes by `(experiment, lineage_id) -> {t: [row_indices]}`, enabling O(1) positive lookup that naturally crosses division boundaries. + +3. **collate_fn=lambda x: x:** Both train and val dataloaders use identity collation because `__getitems__` returns an already-batched dict (not a list of individual samples). `FlexibleBatchSampler` provides batched indices. + +4. **hcl_beta on DataModule:** Stored for Lightning CLI YAML discoverability but not functionally used by the DataModule.

Errors are good and warn us of issues in the script. For example, prefer `value = my_dictionary['key']` over `value = my_dictionary.get('key')` since the former will raise a `KeyError` to signal that the underlying data is not behaving as expected. + +Only catch errors when there is a good reason to do so: for example, catching HTTP errors in order to retry a request. + +If you find yourself writing an if statement, fallback, or except statement designed to avoid errors, ask yourself if it would be better to raise the error as a signal to the user. + + +### Use Real Integration Tests +Tests should directly *import* the actual code we are trying to test. For example, if you are trying to test `my_function` on some sample data, your test should directly import `my_function` and run it on the sample data.

Clean up only your own mess. + +When editing existing code: + +Don't "improve" adjacent code, comments, or formatting. +Don't refactor things that aren't broken. +Match existing style, even if you'd do it differently. +If you notice unrelated dead code, mention it - don't delete it. +When your changes create orphans: + +Remove imports/variables/functions that YOUR changes made unused. +Don't remove pre-existing dead code unless asked. +The test: Every changed line should trace directly to the user's request. + +4.
