Release 0.26.0

Major Features and Improvements

  • Created a docker image that contains a TF model server with struct2tensor ops linked. This docker image is available at gcr.io/tfx-oss-public/s2t_tf_serving .
  • Add support for string_views for intermediate serialized protos. To use, set the option "use_string_view" in CalculateOptions to true. string_views are potentially more memory bandwidth efficient depending on the depth and complexity of the input proto.

Bug Fixes and Other Changes

  • Depends on tensorflow-metadata>=0.26,<0.27.

Release 0.25.0

Major Features and Improvements

  • From this release Struct2Tensor will also be hosting nightly packages on https://pypi-nightly.tensorflow.org. To install the nightly package use the following command:

    pip install --extra-index-url https://pypi-nightly.tensorflow.org/simple struct2tensor

    Note: These nightly packages are unstable and breakages are likely to happen. The fix could often take a week or more depending on the complexity involved for the wheels to be available on the PyPI cloud service. You can always use the stable version of struct2tensor available on PyPI by running the command pip install struct2tensor .

Bug Fixes and Other Changes

  • Update init.py to import the API, instead of just the modules.
  • Provide an init.py for struct2tensor.expression_impl directory. This is meant for power users.
  • Update python notebook to use import style.
  • Fix bug in prensor_to_structured_tensor.
  • Depends on tensorflow-metadata>=0.25,<0.26.
  • Depends on pyarrow>=0.17,<1.
