22. IPU TensorFlow Addons API changes

22.1. Release 3.0

The following changes have been made to the TensorFlow API in the Poplar SDK version 3.0. This may require you to change your code.

22.1.1. Breaking changes

Warning

These will require changes to any code that uses them.

Removal of deprecated APIs:

The available_memory_proportion_fwd and available_memory_proportion_bwd arguments have been removed from the following layers: ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnLSTM, ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnDynamicLSTM, ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnGRU, ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnDynamicGRU, ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnAUGRU.

22.2. Release 2.5

The following changes have been made to the IPU TensorFlow Addons API in the Poplar SDK version 2.5. This may require you to change your code.

22.2.1. Non-breaking changes

RNN available_memory_proportion_fwd/available_memory_proportion_bwd deprecated

The available_memory_proportion_fwd and available_memory_proportion_bwd arguments have been deprecated and will be removed from the following layers in a future release:

ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnLSTM

ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnDynamicLSTM

ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnGRU

ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnDynamicGRU

ipu_tensorflow_addons.v1.layers.rnn_ops.PopnnAUGRU

These values are now set using the 'availableMemoryProportion' key of the options and options_bwd arguments correspondingly.

22.3. Release 2.4

First IPU TensorFlow Addons release.
