Breaking Changes
* `tf.train.experimental.enable_mixed_precision_graph_rewrite` is removed, as
the API only works in graph mode and is not customizable. The function is
still accessible under
`tf.compat.v1.mixed_precision.enable_mixed_precision_graph_rewrite`, but it
is recommended to use the
[Keras mixed precision API](https://www.tensorflow.org/guide/mixed_precision)
instead.
* `tf.lite`:
* Remove `experimental.nn.dynamic_rnn`, `experimental.nn.TfLiteRNNCell`
and `experimental.nn.TfLiteLSTMCell` since they're no longer supported.
It's recommended to just use
[keras lstm](https://www.tensorflow.org/api_docs/python/tf/keras/layers/LSTM)
instead.
* `tf.keras`:
* Keras been split into a separate PIP package (`keras`), and its code has
been moved to the GitHub
repository[keras-team/keras](http://github.com/keras-team/keras). The
API endpoints for `tf.keras` stay unchanged, but are now backed by the
`keras` PIP package. The existing code in tensorflow/python/keras is a
staled copy and will be removed in future release (2.7). Please remove
any imports to `tensorflow.python.keras` and replace them with public
tf.keras API instead.
* The methods `Model.to_yaml()` and `keras.models.model_from_yaml` have
been replaced to raise a `RuntimeError` as they can be abused to cause
arbitrary code execution. It is recommended to use JSON serialization
instead of YAML, or, a better alternative, serialize to H5.
Known Caveats
* TF Core:
* A longstanding bug in `tf.while_loop`, which caused it to execute
sequentially, even when `parallel_iterations>1`, has now been fixed.
However, the increased parallelism may result in increased memory use.
Users who experience unwanted regressions should reset their
`while_loop`'s `parallel_iterations` value to 1, which is consistent
with prior behavior.
Major Features and Improvements
* `tf.keras`:
* Keras has been split into a separate PIP package (`keras`), and its code
has been moved to the GitHub repository
[keras-team/keras](http://github.com/keras-team/keras). The API
endpoints for `tf.keras` stay unchanged, but are now backed by the
`keras` PIP package. All Keras-related PRs and issues should now be
directed to the GitHub repository.
[keras-team/keras](http://github.com/keras-team/keras).
* `tf.keras.utils.experimental.DatasetCreator` now takes an optional
`tf.distribute.InputOptions` for specific options when used with
distribution.
* `tf.keras.experimental.SidecarEvaluator` is now available for a program
intended to be run on an evaluator task, which is commonly used to
supplement a training cluster running with
`tf.distribute.experimental.ParameterServerStrategy` (see
`https://www.tensorflow.org/tutorials/distribute/parameter_server_training).
It can also be used with single-worker training or other strategies. See
docstring for more info.
* Preprocessing layers moved from experimental to core.
* Import paths moved from `tf.keras.layers.preprocessing.experimental`
to `tf.keras.layers`.
* Updates to Preprocessing layers API for consistency and clarity:
* `StringLookup` and `IntegerLookup` default for `mask_token` changed
to `None`. This matches the default masking behavior of `Hashing`
and `Embedding` layers. To keep existing behavior, pass
`mask_token=""` during layer creation.
* Renamed `"binary"` output mode to `"multi_hot"` for
`CategoryEncoding`, `StringLookup`, `IntegerLookup`, and
`TextVectorization`. Multi-hot encoding will no longer automatically
uprank rank 1 inputs, so these layers can now multi-hot encode
unbatched multi-dimensional samples.
* Added a new output mode `"one_hot"` for `CategoryEncoding`,
`StringLookup`, `IntegerLookup`, which will encode each element in
an input batch individually, and automatically append a new output
dimension if necessary. Use this mode on rank 1 inputs for the old
`"binary"` behavior of one-hot encoding a batch of scalars.
* `Normalization` will no longer automatically uprank rank 1 inputs,
allowing normalization of unbatched multi-dimensional samples.
* `tf.lite`:
* The recommended Android NDK version for building TensorFlow Lite has
been changed from r18b to r19c.
* Supports int64 for mul.
* Supports native variable builtin ops - ReadVariable, AssignVariable.
* Converter:
* Experimental support for variables in TFLite. To enable through
conversion, users need to set
`experimental_enable_resource_variables` on tf.lite.TFLiteConverter
to True. Note: mutable variables is only available using
`from_saved_model` in this release, support for other methods is
coming soon.
* Old Converter (TOCO) is getting removed from next release. It's been
deprecated for few releases already.
* `tf.saved_model`:
* SavedModels can now save custom gradients. Use the option
`tf.saved_model.SaveOption(experimental_custom_gradients=True)` to
enable this feature. The documentation in
[Advanced autodiff](https://www.tensorflow.org/guide/advanced_autodiff#custom_gradients)
has been updated.
* Object metadata has now been deprecated and no longer saved to the
SavedModel.
* TF Core:
* Added `tf.config.experimental.reset_memory_stats` to reset the tracked
peak memory returned by `tf.config.experimental.get_memory_info`.
* `tf.data`:
* Added `target_workers` param to `data_service_ops.from_dataset_id` and
`data_service_ops.distribute`. Users can specify `"AUTO"`, `"ANY"`, or
`"LOCAL"` (case insensitive). If `"AUTO"`, tf.data service runtime
decides which workers to read from. If `"ANY"`, TF workers read from any
tf.data service workers. If `"LOCAL"`, TF workers will only read from
local in-processs tf.data service workers. `"AUTO"` works well for most
cases, while users can specify other targets. For example, `"LOCAL"`
would help avoid RPCs and data copy if every TF worker colocates with a
tf.data service worker. Currently, `"AUTO"` reads from any tf.data
service workers to preserve existing behavior. The default value is
`"AUTO"`.
Bug Fixes and Other Changes
* TF Core:
* Added `tf.lookup.experimental.MutableHashTable`, which provides a
generic mutable hash table implementation.
* Compared to `tf.lookup.experimental.DenseHashTable` this offers
lower overall memory usage, and a cleaner API. It does not require
specifying a `delete_key` and `empty_key` that cannot be inserted
into the table.
* Added support for specifying number of subdivisions in all reduce host
collective. This parallelizes work on CPU and speeds up the collective
performance. Default behavior is unchanged.
* Add an option `perturb_singular` to `tf.linalg.tridiagonal_solve` that
allows solving linear systems with a numerically singular tridiagonal
matrix, e.g. for use in inverse iteration.
* Added `tf.linalg.eigh_tridiagonal` that computes the eigenvalues of a
Hermitian tridiagonal matrix.
* `tf.constant` now places its output on the current default device.
* SavedModel
* Added `tf.saved_model.experimental.TrackableResource`, which allows
the creation of custom wrapper objects for resource tensors.
* Added a SavedModel load option to allow restoring partial
checkpoints into the SavedModel. See
[`tf.saved_model.LoadOptions`](https://www.tensorflow.org/api_docs/python/tf/saved_model/LoadOptions)
for details.
* Added a new op `SparseSegmentSumGrad` to match the other sparse segment
gradient ops and avoid an extra gather operation that was in the
previous gradient implementation.
* Added a new session config setting `internal_fragmentation_fraction`,
which controls when the BFC Allocator needs to split an oversized chunk
to satisfy an allocation request.
* Added `tf.get_current_name_scope()` which returns the current full name
scope string that will be prepended to op names.
* `tf.data`:
* Promoting `tf.data.experimental.bucket_by_sequence_length` API to
`tf.data.Dataset.bucket_by_sequence_length` and deprecating the
experimental endpoint.
* Promoting `tf.data.experimental.get_single_element` API to
`tf.data.Dataset.get_single_element` and deprecating the experimental
endpoint.
* Promoting `tf.data.experimental.group_by_window` API to
`tf.data.Dataset.group_by_window` and deprecating the experimental
endpoint.
* Promoting `tf.data.experimental.RandomDataset` API to
`tf.data.Dataset.random` and deprecating the experimental endpoint.
* Promoting `tf.data.experimental.scan` API to `tf.data.Dataset.scan` and
deprecating the experimental endpoint.
* Promoting `tf.data.experimental.snapshot` API to
`tf.data.Dataset.shapshot` and deprecating the experimental endpoint.
* Promoting `tf.data.experimental.take_while` API to
`tf.data.Dataset.take_while` and deprecating the experimental endpoint.
* Promoting `tf.data.experimental.ThreadingOptions` API to
`tf.data.ThreadingOptions` and deprecating the experimental endpoint.
* Promoting `tf.data.experimental.unique` API to `tf.data.Dataset.unique`
and deprecating the experimental endpoint.
* Added `stop_on_empty_dataset` parameter to `sample_from_datasets` and
`choose_from_datasets`. Setting `stop_on_empty_dataset=True` will stop
sampling if it encounters an empty dataset. This preserves the sampling
ratio throughout training. The prior behavior was to continue sampling,
skipping over exhausted datasets, until all datasets are exhausted. By
default, the original behavior (`stop_on_empty_dataset=False`) is
preserved.
* Removed previously deprecated tf.data statistics related APIs:
* `tf.data.Options.experimental_stats`
* `tf.data.experimental.StatsAggregator`
* `tf.data.experimental.StatsOptions.*`
* `tf.data.experimental.bytes_produced_stats`
* `tf.data.experimental.latency_stats`
* Removed the following experimental tf.data optimization APIs:
* `tf.data.experimental.MapVectorizationOptions.*`
* `tf.data.experimental.OptimizationOptions.filter_with_random_uniform_fusion`
* `tf.data.experimental.OptimizationOptions.hoist_random_uniform`
* `tf.data.experimental.OptimizationOptions.map_vectorization` *
`tf.data.experimental.OptimizationOptions.reorder_data_discarding_ops`
* `tf.keras`:
* Fix usage of `__getitem__` slicing in Keras Functional APIs when the
inputs are `RaggedTensor` objects.
* Add `keepdims` argument to all `GlobalPooling` layers.
* Add `include_preprocessing` argument to `MobileNetV3` architectures to
control the inclusion of `Rescaling` layer in the model.
* Add optional argument (`force`) to `make_(train|test|predict)_funtion`
methods to skip the cached function and generate a new one. This is
useful to regenerate in a single call the compiled training function
when any `.trainable` attribute of any model's layer has changed.
* Models now have a `save_spec` property which contains the `TensorSpec`
specs for calling the model. This spec is automatically saved when the
model is called for the first time.
* `tf.linalg`:
* Add `CompositeTensor` as a base class to `LinearOperator`.
* `tf.lite`:
* Fix mean op reference quantization rounding issue.
* Added `framework_stable` BUILD target, which links in only the
non-experimental TF Lite APIs.
* Remove deprecated Java `Interpreter` methods:
* `modifyGraphWithDelegate` - Use `Interpreter.Options.addDelegate`
* `setNumThreads` - Use `Interpreter.Options.setNumThreads`
* Add Conv3DTranspose as a builtin op.
* `tf.summary`:
* Fix `tf.summary.should_record_summaries()` so it correctly reflects when
summaries will be written, even when `tf.summary.record_if()` is not n
effect, by returning True tensor if default writer is present.
* Grappler:
* Disable default Grappler optimization timeout to make the optimization
pipeline deterministic. This may lead to increased model loading time,
because time spent in graph optimizations is now unbounded (was 20
minutes).
* Deterministic Op Functionality (enabled by setting `TF_DETERMINISTIC_OPS` to
`"true"` or `"1"`):
* Add a deterministic GPU implementation of
`tf.nn.softmax_cross_entropy_with_logits`. See PR
[49178](https://github.com/tensorflow/tensorflow/pull/49178).
* Add a deterministic CPU implementation of `tf.image.crop_and_resize`.
See PR [48905](https://github.com/tensorflow/tensorflow/pull/48905).
* Add determinism-unimplemented exception-throwing to the following ops.
When op-determinism is expected, an attempt to use the specified paths
through the following ops on a GPU will cause
`tf.errors.UnimplementedError` (with an understandable message) to be
thrown.
* `tf.nn.sparse_softmax_cross_entropy_with_logits` forwards and/or
backwards. See PR
[47925](https://github.com/tensorflow/tensorflow/pull/47925).
* `tf.image.crop_and_resize` gradient w.r.t. either `image` or
`boxes`. See PR
[48905](https://github.com/tensorflow/tensorflow/pull/48905).
* `tf.sparse.sparse_dense_matmul` forwards. See PR
[50355](https://github.com/tensorflow/tensorflow/pull/50355).
