your generated code is out of date and must be regenerated with protoc ＞= 3.19.0.

问题：在配置paddle库的时候，import paddle报错。

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

解决方法：把protobuf卸了重装，亲测有效！

pip uninstall protobuf（注意！是protobuf，不是protoc）

pip install protobuf==3.19.0
