2.0.3

Dev/test dep upgrades:

  • TF 1.13.2 => 1.15.2
  • Keras 2.2.4 => 2.3.1

2.0.2

Remove problematic type hints

2.0.1

Fix Keras import from Tensorflow

2.0.0

Semantic versioning can't be maintained while trying to track version numbers to TF; that didn't last long. :)

This is a major version bump because the default behavior changes with introduction of inherit_optimizer arg to AltModelCheckpoint(...). When inherit_optimizer is True (the default), the optimizer of the base model (e.g. the multi-gpu model) will be saved with the alternate model so training can be resumed later from the saved file.

Pass inherit_optimizer=False to preserve old behavior (save alternate model optimizer as-is, which is not typically useful for the common multi-gpu model use case of this library).

1.13.0

  • BREAKING: Tensorflow/Keras dependencies not enforced since user can use either
    • How to migrate: specify your own version in requirements.txt or Pipfile and install accordingly
  • BREAKING: Provide versions of AltModelCheckpoint linked against Keras standalone and TF packaged Keras
    • Update your imports from alt_model_checkpoint.AltModelCheckpoint to alt_model_checkpoint.[tensorflow|keras].AltModelCheckpoint`
  • Fix TF version to ~1.13 and associated Keras version (~2.2.4) according to breaking changes in upstream ModelCheckpoint
  • Match package minor version to TF minor version

1.0.2

Upgrade deps

1.0.1

Upgrade dependencies, esp. for requests==2.20.0 security patch

1.0.0

Initial release
