Areas of improvement

  • Bug fixes
  • Performance improvements
  • Improvements to example scripts

API changes

  • Allow for stateful metrics in model.compile(..., metrics=[...]). A stateful metric inherits from Layer, and implements __call__ and reset_states.
  • Support constants argument in StackedRNNCells.
  • Enable some TensorBoard features in the TensorBoard callback (loss and metrics plotting) with non-TensorFlow backends.
  • Add reshape argument in model.load_weights(), to optionally reshape weights being loaded to the size of the target weights in the model considered.
  • Add tif to supported formats in ImageDataGenerator.
  • Allow auto-GPU selection in multi_gpu_model() (set gpus=None).
  • In LearningRateScheduler callback, the scheduling function now takes an argument: lr, the current learning rate.

Breaking changes

  • In ImageDataGenerator, change default interpolation of image transforms from nearest to bilinear. This should probably not break any users, but it is a change of behavior.
