TypeError: Descriptors cannot not be created directly.（Tensorflow安装问题）

笔者在调试Tacotron2官模时，调取tensorflow时出现了这样的错误。

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

显而易见，问题原因：

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.

再加上建议处理方法：

1. Downgrade the protobuf package to 3.20.x or lower.

所以这个地方直接pip install protobuf==3.20.
笔者的版本是4.21.12，在重新安装protobuf后解决了问题，在此之前也是因为tensorflow版本的问题重新将cuda版本从12降为了10.2。
