Tensorflow-text

Bug Fixes and Other Changes

* Update `__init__.py`: Added a `__version__` variable
* Fixes the benchmark suite for graph mode. While using tf.function prevented caching, it was also causing the graph being tested to rebuild each time. Using placeholder instead fixes this.
* Pin nightly version.
* Remove TF patch as it is not needed anymore. The code is in core TF.
* Typos
* Format and lint NBs, add images
* Add a couple notes to the BertTokenizer docs.
* Narrative docs migration: TF Core -> TF Text
* Update nmt_with_attention
* Moved examples of a few API docs above the args sections to better match other formats.
* Fix NBs
* Update Installation from source instruction.
* Add SplitterWithOffsets as an exported symbol.
* Fix a note to the BertTokenizer docs.
* Remove unused index.md
* Convert tensorflow_text to use public TF if possible.
* Fix failing notebooks.
* Create user_ops BUILD file.
* Remove unnecessary METADATA.
* Replace tf.compat.v2.xxx with tf.xxx, since tf_text is using tf2 only.
* Fix load_data function in nmt tutorial
* Update tf.data.AUTOTUNE in Fine-tuning a BERT model
* Switch TF to OSS keras (1/N).
* added *sub*spaces
* Disable TSAN for tutorial tests that may run for >900sec when TSAN is enabled.
* Adds a short description to the main landing page of our GitHub repo to point users to the tf.org subsite.
* Phrasing fix to TF Transformer tutorial.
* Disable RTTI when building Tf.Text kernels for mobile
* Migrate the references in third_party/toolchains directory as it is going to be deleted soon.
* Fix bug in RoundRobinTrimmer. Previously the stopping condition was merging and combining from across different batches. Instead now the stopping condition is first determined in each batch, then aggregated.
* Set mask_token='' to make it work with TF 2.6.0
* Builds TF Text with C++14 by default. This is already done by TensorFlow, and the TF Lite shim has C++14 features used within; thus, this is needed to build kernels against it.
* This is a general clean up to the build files. The previous tf_deps paradigm was confusing. By encapsulating everything into a single call lib, I'm hoping this makes it easier to understand and follow.
* Update the WORKSPACE to not use the same "workspace" name when initializing TensorFlow.

We want to particularly point out that guides, tutorials, and API docs are currently being published to http://tensorflow.org/text ! This should make it easier for users to find our documentation. We worked hard on improving docs across the board, so feel free to let us know if further clarification is needed.

Major Features and Improvements

* API docs, guides, & tutorial are now available on http://tensorflow.org/text
* New guides & tutorials including: tokenizers, subwords tokenizer, and BERT text preprocessing guide.
* Add RoundRobinTrimmer
* Add a function to generate a BERT vocab from a tf.data.Dataset.
* Add detokenize methods for BertTokenizer and WordpieceTokenizer.
* Enable NFD and NFKD in NormalizeWithOffset op

Bug Fixes and Other Changes

* Many API updates (eg. adding descriptions & examples) to various ops.
* Let SentencePieceTokenizer optionally return the nbest tokenizations instead of sampling from them.
* Fix a bug in split mode tokenizers that caused tests to fail on Windows.
* Fix broadcasting bugs in RoundRobinTrimmer
* Add WordpieceTokenizeWithOffsets with ALLOW_STATEFUL_OP_FOR_DATASET_FUNCTIONS for tf.data
* Remove PersistentTensor from sentencepiece_kernels.cc
* Document examples are now tested.
* Fix benchmarking of graph mode ops through use of tf.function.
* Set the default for mask_token for StringLookup and IntegerLookup to None
* Update the sentence_breaking_ops docstring to indicate that it's deprecated.
* Adding an i18n-friendly BasicTokenizer that can preserve accents
* For Windows, always include ICU data files since they need to be built in statically.
* Rename documentation file WordShape.md to WordShape_cls.md. Fix 361.
* Convert input to tensor to allow for numpy inputs to state based sentence breaker.
* Add classifiers to py packages and fix header image.
* Fix for the model server test.
* Update regression test for break_sentences_with_offsets.
* Add a shape attribute to the ToDense Keras layer.
* Add support for [batch, 1] shaped inputs in StateBasedSentenceBreaker
* Fix for the model server test.
* Refactor saved_model.py to make it easier to comment out blocks of related code to identify problems.
* Add regression test for Find Source Offsets
* Fix unselectable_ids shape check in ItemSelector.
* Switch out architecture image in tf.Text documentation.
* Fix regression test for state_based_sentence_breaker_v2
* Update run_build with enable_runfiles flag.
* Update the version of bazel_skylib to match TF's and fix a possible visibility issue.
* Simplify tf-text WORKSPACE, by relying on tf_workspace().
* Update transformer.ipynb to use a saved text.BertTokenizer
* Update mobile targets to use :mobile rather than separate :android & :ios targets.
* Make tools part of the tensorflow_text pip package.
* Import tools from the tf-text package, instead of cloning the git repo.

Major Features and Improvements

* Add a subwords tokenizer tutorial to text/examples.

Breaking Changes

Bug Fixes and Other Changes

* Other:
* For Windows, always include ICU data files since they need to be built in statically.
* Patches TF to fix windows builds to not look for a python3 executable.
* Rename documentation file WordShape.md to WordShape_cls.md. The problem is on MacOS (and maybe Windows) this filename collides with wordshape.md, because the filesystem does not differentiate cases for the files. This is purely a QOL change for anybody checking out the library on a non-Linux platform. Fix 361.
* Convert input to tensor to allow for numpy inputs to state based sentence breaker.
* Add classifiers to py packages and fix header image.
* fix bad rendering for add_eos add_bos description in SentencepieceTokenizer.md
* Fix for the model server test. Make sure our test tensors have the expected
* Update regression test for break_sentences_with_offsets.
* Add a `shape` attribute to the `ToDense` Keras layer.
* Add support for [batch, 1] shaped inputs in StateBasedSentenceBreaker
* Fix for the model server test. The result of the tokenize() method of
* Refactor saved_model.py to make it easier to comment out blocks of related code to identify problems. Also moved out the vocab for Wordpiece due to a tf bug.
* Update documentation for SplitMergeFromLogitsTokenizer
* Add regression test for Find Source Offsets
* Fix `unselectable_ids` shape check in ItemSelector.
* changing two tests, to debug failure on Kokoro Windows build.
* Switch out architecture image in tf.Text documentation.
* Fix regression test for state_based_sentence_breaker_v2
* Update run_build with enable_runfiles flag.
* Update the version of bazel_skylib to match TF's and fix a possible visibility issue.
