构建TensorFlow pip软件包时有告警信息提示的解决办法

问题现象描述

构建TensorFlow pip软件包时有告警信息提示。部分告警信息如下：

!!
  check.warn(importable)
/usr/local/lib/python3.9/site-packages/setuptools/command/build_py.py:204: _Warning: Package 'tensorflow.xla_aot_runtime_src.tensorflow.tsl.platform' is absent from the `packages` configuration.
!!

        ********************************************************************************
        ############################
        # Package would be ignored #
        ############################
        Python recognizes 'tensorflow.xla_aot_runtime_src.tensorflow.tsl.platform' as an importable package[^1],
        but it is absent from setuptools' `packages` configuration.

        This leads to an ambiguous overall configuration. If you want to distribute this
        package, please make sure that 'tensorflow.xla_aot_runtime_src.tensorflow.tsl.platform' is explicitly added
        to the `packages` configuration field.

        Alternatively, you can also rely on setuptools' discovery methods
        (for example by using `find_namespace_packages(...)`/`find_namespace:`
        instead of `find_packages(...)`/`find:`).

        You can read more about "package discovery" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html

        If you don't want 'tensorflow.xla_aot_runtime_src.tensorflow.tsl.platform' to be distributed and are
        already explicitly excluding 'tensorflow.xla_aot_runtime_src.tensorflow.tsl.platform' via
        `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
        you can try to use `exclude_package_data`, or `include-package-data=False` in
        combination with a more fine grained `package-data` configuration.

        You can read more about "package data files" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/datafiles.html


        [^1]: For Python, any directory (with suitable naming) can be imported,
              even if it does not contain any `.py` files.
              On the other hand, currently there is no concept of package data
              directory, all directories are treated like packages.
        ********************************************************************************

关键过程、根本原因分析

关键错误信息：setuptools的方法随着版本演进，发生变化，使用find_namespace_packages(...)/find_namespace:替换find_packages(...)/find:。

Alternatively, you can also rely on setuptools' discovery methods(for example by using `find_namespace_packages(...)`/`find_namespace:`instead of `find_packages(...)`/`find:`).

结论、解决方案及效果

1. 查询当前环境安装的setuptools版本。

   pip3 list | grep setuptools

   版本信息：

   

2. setuptools版本降级。

   pip3 uninstall setuptools
   pip3 install setuptools==56.0.0

   

   56.0.0版本的setuptools安装成功。

   

   目前已经验证了setuptools 42.0.2，50.0.0，56.0.0，57.0.0版本均可以消除告警信息。

3. 重新构建出包。

   ./bazel-bin/tensorflow/tools/pip_package/build_pip_package ./output
