help, No module named 'torch'

[2026-06-16T10:09:54.188Z] [RUNTIME] [Registry] ERROR loading extension 'modly-trellis2-gguf-extension': No module named 'torch'

1. Check the venv exists and has torch
   modly\extensions\trellis2\venv\Lib\site-packages\torch\

• Folder missing → setup never created the venv.
• venv exists but no torch → setup failed mid-install.

2. Get the [setup] logs from the install/Repair run. Look for the line:
   [setup] Installing PyTorch …
   and whatever error follows it. Most likely causes:

• network blocked to download.pytorch.org (proxy/firewall),
• not enough disk space (torch CUDA ≈ 3–5 GB),
• the python_exe passed to setup was invalid → venv never built.

3. Fix: run Repair on the extension to re-execute setup.py.

i dont have this at all, modly\extensions\trellis2\venv\Lib\site-packages\torch\ and i cant run repair.

[Lorchie]

You don't have this ?

If you don't have uninstall trellis 2 GGUF and reinstall

[simp91]

i have that but when i click on repair it says, no setup py found for this extension, but i have.

[simp91]

thanks for trying to help me :) but i need python 3.10 in modly for it to work, setup py needs it for my pc.

Hey @simp91,
The "no setup.py found" error usually means the extension folder isn't named exactly modly-trellis2-gguf-extension — Modly can't find setup.py so Repair breaks.
Easiest fix:

Models page → Trellis.2 GGUF → Uninstall
Models page → "Add extension" → paste https://github.com/lightningpixel/modly-trellis2-gguf-extension
Let the install complete fully before launching

If it still fails after reinstall, you can create the venv manually with Python 3.10:

Delete the broken venv
rmdir /s /q "C:\path\to\modly\extensions\modly-trellis2-gguf-extension\venv"

Create a new venv with Python 3.10
C:\Python310\python.exe -m venv "C:\path\to\modly\extensions\modly-trellis2-gguf-extension\venv"

Run setup.py manually
C:\Python310\python.exe "C:\path\to\modly\extensions\modly-trellis2-gguf-extension\setup.py" "{"python_exe":"
C:\Python310\python.exe","ext_dir":"C:\path\to\modly\extensions\modly-trellis2-gguf-extension","gpu_sm":86,"cuda_version":126}"

Replace the paths with your actual install location, and gpu_sm with your GPU (86 = RTX 3080/3090, 89 = RTX 4090, 120 = RTX 5xxx). What GPU do you have?

i got i working abit but now, this, Error: Error invoking remote method 'fs:readFileBase64': Error: ENOENT: no such file or directory, open ''

[simp91]

Thanks again for help, it runs perfect now, i installed the extension in a separate folder manualy and moved it back to original place after.
