Release v1.4.6

Bug fixes

Release v1.4.5

Bug fixes

• When running in parallel, the chief used to start to block in tuner.__init__(). However, it makes more sense to block when calling tuner.search(). Now, it is fixed.
• Could not do from keras_tuner.engine.hypermodel import HyperModel. It is now fixed.
• Could not do from keras_tuner.engine.hyperparameters import HyperParameters. It is now fixed.

  keras_tuner.some_private_api, it will now be
  keras_tuner.src.some_private_api.

New features

• Support Keras Core with multi-backend.

Release v1.3.5

Breaking changes

• Removed TensorFlow from the required dependencies of KerasTuner. The user need
  to install TensorFlow either separately with KerasTuner or with
  pip install keras_tuner[tensorflow]. This change is because some people may
  want to use KerasTuner with tensorflow-cpu instead of tensorflow.

Bug fixes

• KerasTuner used to require protobuf version to be under 3.20. The limit is
  removed. Now, it support both protobuf 3 and 4.
