Bump tensorflow from 1.14.0 to 2.12.1

[dependabot]

Bumps tensorflow from 1.14.0 to 2.12.1.

Release notes

Sourced from tensorflow's releases.

TensorFlow 2.12.1

Release 2.12.1

Bug Fixes and Other Changes

• The use of the ambe config to build and test aarch64 is not needed. The ambe config will be removed in the future. Making cpu_arm64_pip.sh and cpu_arm64_nonpip.sh more similar for easier future maintenance.

TensorFlow 2.12.0

Release 2.12.0

TensorFlow

Breaking Changes

• Build, Compilation and Packaging

  • Removed redundant packages tensorflow-gpu and tf-nightly-gpu. These packages were removed and replaced with packages that direct users to switch to tensorflow or tf-nightly respectively. Since TensorFlow 2.1, the only difference between these two sets of packages was their names, so there is no loss of functionality or GPU support. See https://pypi.org/project/tensorflow-gpu for more details.

• tf.function:

  • tf.function now uses the Python inspect library directly for parsing the signature of the Python function it is decorated on. This change may break code where the function signature is malformed, but was ignored previously, such as:
    • Using functools.wraps on a function with different signature
    • Using functools.partial with an invalid tf.function input
  • tf.function now enforces input parameter names to be valid Python identifiers. Incompatible names are automatically sanitized similarly to existing SavedModel signature behavior.
  • Parameterless tf.functions are assumed to have an empty input_signature instead of an undefined one even if the input_signature is unspecified.
  • tf.types.experimental.TraceType now requires an additional placeholder_value method to be defined.
  • tf.function now traces with placeholder values generated by TraceType instead of the value itself.

• Experimental APIs tf.config.experimental.enable_mlir_graph_optimization and tf.config.experimental.disable_mlir_graph_optimization were removed.

Major Features and Improvements

• Support for Python 3.11 has been added.

• Support for Python 3.7 has been removed. We are not releasing any more patches for Python 3.7.

• tf.lite:

  • Add 16-bit float type support for built-in op fill.
  • Transpose now supports 6D tensors.
  • Float LSTM now supports diagonal recurrent tensors: https://arxiv.org/abs/1903.08023

• tf.experimental.dtensor:

  • Coordination service now works with dtensor.initialize_accelerator_system, and enabled by default.
  • Add tf.experimental.dtensor.is_dtensor to check if a tensor is a DTensor instance.

• tf.data:

  • Added support for alternative checkpointing protocol which makes it possible to checkpoint the state of the input pipeline without having to store the contents of internal buffers. The new functionality can be enabled through the experimental_symbolic_checkpoint option of tf.data.Options().
  • Added a new rerandomize_each_iteration argument for the tf.data.Dataset.random() operation, which controls whether the sequence of generated random numbers should be re-randomized every epoch or not (the default behavior). If seed is set and rerandomize_each_iteration=True, the random() operation will produce a different (deterministic) sequence of numbers every epoch.
