  • clu.deterministic_training
  • clu.metric_writers
  • clu.periodic_actions
  • clu.platform
  • clu.profiler

v0.0.1-alpha.2

  • Adds metrics module and some minor changes.

v0.0.1a3

  • Added metric_writers.TorchTensorboardWriter

v0.0.2

  • Added preprocess_spec.
  • Improvements to periodic_actions.

v0.0.3

  • metric_writers: Lets SummaryWriter write nested dictionaries.
  • internal: Adds async.Pool.
  • preprocess_spec: Support nested dictionaries.
  • profile: Use JAX profiler APIs instead of TF profiler APIs.

v0.0.4

deterministic_data

  • Support non-positive input value for pad_up_to_batches.
  • Support padding dataset when data dimension is unknown.
  • Support TFDS specs in get_read_instruction_for_host.
  • Allow changing drop_remainder for batching.
  • Add RemainderOptions in deterministic_data.

metric_writers

  • Support multiple writers in metric_writers.ensure_flushes.

metrics

  • Makes internal.flatten_dict() work with ConfigDicts.
  • Forwards mask model output to metrics created via Metric.from_output().
  • Forwards mask model output to metrics created via Metric.from_fun().
  • Added Collections.unreplicate(), Collections.create().

periodic_actions

  • Formats long time strings in '{days}d{hours}h{mins}m' format.

preprocess_spec

  • Make feature description of features in PreprocessFn more compact.
  • Better type check in preprocess_spec.get_all_ops().

Documentation:

  • Added clu_synopsis.ipynb Colab

v0.0.5

  • Log error instead of failing when profiler.start() raises an exception.
  • Makes periodic_actions.ProgressUpdate show total number of steps.
  • Makes AsyncWriter non-blocking wrt JAX async computations.
  • Adds clu_synopsis.ipynb Colab as initial documentation.
  • Restore Checkpoint without providing the state
  • Makes PreprocessFn addable.
  • Allow n-dimensional arrays (and masks) to be passed to Metrics.Average().
