* Introduce float8 training (#19488) * Add float8 training support * Add tests for fp8 training * Add `quantize_and_dequantize` test * Fix bugs and add float8 correctness tests * Cleanup * Address comments and cleanup * Add docstrings and some minor refactoring * Add `QuantizedFloat8DTypePolicy` * Add dtype policy setter * Fix torch dynamo issue by using `self._dtype_policy` * Improve test coverage * Add LoRA to ConvND layers (#19516) * Add LoRA to `BaseConv` * Add tests * Fix typo * Fix tests * Fix tests * Add path to run keras on dm-tree when optree is not available. * feat(losses): add Tversky loss implementation (#19511) * feat(losses): add Tversky loss implementation * adjusted documentation * Update KLD docs * Models and layers now return owned metrics recursively. (#19522) - added `Layer.metrics` to return all metrics owned by the layer and its sub-layers recursively. - `Layer.metrics_variables` now returns variables from all metrics recursively, not just the layer and its direct sub-layers. - `Model.metrics` now returns all metrics recursively, not just the model level metrics. - `Model.metrics_variables` now returns variables from all metrics recursively, not just the model level metrics. - added test coverage to test metrics and variables 2 levels deep. This is consistent with the Keras 2 behavior and how `Model/Layer.variables` and `Model/Layer.weights` work. * Update IoU ignore_class handling * Fix `RandomBrightness`, Enhance `IndexLookup` Initialization and Expand Test Coverage for `Preprocessing Layers` (#19513) * Add tests for CategoryEncoding class in category_encoding_test.py * fix * Fix IndexLookup class initialization and add test cases * Add test case for IndexLookupLayerTest without vocabulary * Fix IndexLookup class initialization * Add normalization test cases * Add test cases for Hashing class * Fix value range validation error in RandomBrightness class * Refactor IndexLookup class initialization and add test cases * Reffix ndexLookup class initialization and afix est cases * Add test for spectral norm * Add missing test decorator * Fix torch test * Fix code format * Generate API (#19530) * API Generator for Keras * API Generator for Keras * Generates API Gen via api_gen.sh * Remove recursive import of _tf_keras * Generate API Files via api_gen.sh * Update APIs * Added metrics from custom `train_step`/`test_step` are now returned. (#19529) This works the same way as in Keras 2, whereby the metrics are returned directly from the logs if the set of keys doesn't match the model metrics. * Use temp dir and abs path in `api_gen.py` (#19533) * Use temp dir and abs path * Use temp dir and abs path * Update Readme * Update API * Fix gradient accumulation when using `overwrite_with_gradient` during float8 training (#19534) * Fix gradient accumulation with `overwrite_with_gradient` in float8 training * Add comments * Fix annotation * Update code path in ignore path (#19537) * Add operations per run (#19538) * Include input shapes in model visualization. * Add pad_to_aspect_ratio feature in ops.image.resize * Add pad_to_aspect_ratio feature in Resizing layer. * Fix incorrect usage of `quantize` (#19541) * Add logic to prevent double quantization * Add detailed info for double quantization error * Update error msg * Add eigh op. * Add keepdim in argmax/argmin. * Fix small bug in model.save_weights (#19545) * Update public APIs. * eigh should work on JAX GPU * Copy init to keras/__init__.py (#19551) * Revert "Copy init to keras/__init__.py (#19551)" (#19552) This reverts commit da9af61. * sum-reduce inlined losses * Remove the dependency on `tensorflow.experimental.numpy` and support negative indices for `take` and `take_along_axis` (#19556) * Remove `tfnp` * Update numpy api * Improve test coverage * Improve test coverage * Fix `Tri` and `Eye` and increase test converage * Update `round` test * Fix `jnp.round` * Fix `diag` bug for iou_metrics * Add op.select. * Add new API for select * Make `ops.abs` and `ops.absolute` consistent between backends. (#19563) - The TensorFlow implementation was missing `convert_to_tensor` - The sparse annotation was unnecessarily applied twice - Now `abs` calls `absolute` in all backends Also fixed TensorFlow `ops.select`. * Add pickle support for Keras model (#19555) * Implement unit tests for pickling * Reformat model_test * Reformat model_test * Rename depickle to unpickle * Rename depickle to unpickle * Reformat * remove a comment * Ellipsis Serialization and tests (#19564) * Serialization and tests * Serialization and tests * Serialization and tests * Make TF one_hot input dtype less strict. * Fix einsum `_int8_call` (#19570) * CTC Decoding for JAX and Tensorflow (#19366) * Tensorflow OP for CTC decoding * JAX op for CTC greedy decoding * Update CTC decoding documentation * Fix linting issues * Fix trailing whitespace * Simplify returns in tensorflow CTC wrapper * Fix CTC decoding error messages * Fix line too long * Bug fixes to JAX CTC greedy decoder * Force int typecast in TF CTC decoder * Unit tests for CTC greedy decoding * Add unit test for CTC beam search decoding * Fix mask index set location in JAX CTC decoding * CTC beam search decoding for JAX * Fix unhandled token repetitions in ctc_beam_search_decode * Fix merge_repeated bug in CTC beam search decode * Fix beam storage and repetition bugs in JAX ctc_decode * Remove trailing whitespace * Fix ordering bug for ties in JAX CTC beam search * Cast sequence lengths to integers in JAX ctc_decode * Remove line break in docstring * CTC beam search decoding for JAX * Fix unhandled token repetitions in ctc_beam_search_decode * Fix merge_repeated bug in CTC beam search decode * Fix beam storage and repetition bugs in JAX ctc_decode * Fix ordering bug for ties in JAX CTC beam search * Generate public api directory * Add not implemented errors for NumPy and Torch CTC decoding * Remove unused redefinition of JAX ctc_beam_search_decode * Docstring edits * Expand nan_to_num args. * Add vectorize op. * list insert requires index (#19575) * Add signature and exclude args to knp.vectorize. * Fix the apis of `dtype_polices` (#19580) * Fix api of `dtype_polices` * Update docstring * Increase test coverage * Fix format * Fix keys of `save_own_variables` and `load_own_variables` (#19581) * Fix JAX CTC test. * Fix loss_weights handling in single output case * Fix JAX vectorize. * Move _tf_keras directory to the root of the pip package. * One time fix to _tf_keras API. * Convert return type imdb.load_data to nparray (#19598) Convert return type imdb.load_data to Numpy array. Currently X_train and X-test returned as list. * Fix typo * fix api_gen.py for legacy (#19590) * fix api_gen.py for legacy * merge api and legacy for _tf_keras * Improve int8 for `Embedding` (#19595) * pin torch < 2.3.0 (#19603) * Clean up duplicated `inputs_quantizer` (#19604) * Cleanup duplicated `inputs_quantizer` and add type check for `input_spec` and `supports_masking` * Revert setter * output format changes and errors in github (#19608) * Provide write permission to action for cache management. (#19606) * Pickle support for all saveables (#19592) * Pickle support * Add keras pickleable mixin * Reformat * Implement pickle all over * reformat * Reformat * Keras saveable * Keras saveable * Keras saveable * Keras saveable * Keras saveable * obj_type * Update pickleable * Saveable logic touchups * Add slogdet op. * Update APIs * Remove unused import * Refactor CTC APIs (#19611) * Add `ctc_loss` and `ctc_decode` for numpy backend, improve imports and tests * Support "beam_search" strategy for torch's `ctc_decode` * Improve `ctc_loss` * Cleanup * Refactor `ctc_decode` * Update docstring * Update docstring * Add `CTCDecode` operation and ensure dtype inference of `ctc_decode` * Fix `name` of `losses.CTC` * update the namex version requirements (#19617) * Add `PSNR` API (#19616) * PSNR * Fix * Docstring format * Remove `PYTORCH_ENABLE_MPS_FALLBACK` flag requirement for mps (#19618) * Remove `PYTORCH_ENABLE_MPS_FALLBACK` flag requirement for mps * Formatting * Implement custom layer insertion in clone_model. (#19610) * Implement custom layer insertion in clone_model. * Add recursive arg and tests. * Add nested sequential cloning test * Fix bidir lstm saving issue. * Fix CI * Fix cholesky tracing with jax * made extract_patches dtype agnostic (#19621) * Simplify Bidirectional implementation * Add support for infinite `PyDataset`s. (#19624) `PyDataset` now uses the `num_batches` property instead of `__len__` to support `None`, which is how one indicates the dataset is infinite. Note that infinite datasets are not shuffled. Fixes #19528 Also added exception reporting when using multithreading / multiprocessing. Previously, the program would just hang with no error reported. * Fix dataset shuffling issue. * Update version string. * Minor fix * Restore version string resolution in pip_build. * Speed up `DataAdapter` tests by testing only the current backend. (#19625) There is no use case for using an iterator for a different backend than the current backend. Also: - limit the number of tests using multiprocessing, the threading tests give us good coverage. - fixed the `test_exception_reported` test, which was not actually exercising the multiprocessing / multithreading cases. - removed unused `init_pool` method. * feat(ops): support np.argpartition (#19588) * feat(ops): support np.argpartition * updated documentation, type-casting, and tf implementation * fixed tf implementation * added torch cast to int32 * updated torch type and API generated files * added torch output type cast * test(trainers): add test_errors implementation for ArrayDataAdapter class (#19626) * Fix torch GPU CI * Fix argmax/argmin keepdims with defined axis in TF * Misc fixes in TF backend ops. * Fix `argpartition` cuda bug in torch (#19634) * fix(ops): specify NonZero output dtype and add test coverage (#19635) * Fix `ops.ctc_decode` (#19633) * Fix greedy ctc decode * Remove print * Fix `tf.nn.ctc_beam_search_decoder` * Change default `mask_index` to `0` * Fix losses test * Update * Ensure the same rule applies for np arrays in autocasting (#19636) * Ensure the same rule applies for np arrays in autocasting * Trigger CI by adding docstring * Update * Update docstring * Fix `istft` and add class `TestMathErrors` in `ops/math_test.py` (#19594) * Fix and test math functions for jax backend * run /workspaces/keras/shell/format.sh * refix * fix * fix _get_complex_tensor_from_tuple * fix * refix * Fix istft function to handle inputs with less than 2 dimensions * fix * Fix ValueError in istft function for inputs with less than 2 dimensions * Return a tuple from `ops.shape` with the Torch backend. (#19640) With Torch, `x.shape` returns a `torch.Size`, which is a subclass of `tuple` but can cause different behaviors. In particular `convert_to_tensor` does not work on `torch.Size`. This fixes #18900 * support conv3d on cpu for TF (#19641) * Enable cudnn rnns when dropout is set (#19645) * Enable cudnn rnns when dropout is set * Fix * Fix plot_model for input dicts. * Fix deprecation warning in torch * Bump the github-actions group with 2 updates (#19653) Bumps the github-actions group with 2 updates: [actions/upload-artifact](https://github.com/actions/upload-artifact) and [github/codeql-action](https://github.com/github/codeql-action).
