paddlehub hub TypeError 错误

pip install paddlehub
hub install chinese_ocr_db_crnn_mobile

提示错误：

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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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

遇到问题，没仔细看，就网上搜，https://blog.csdn.net/qq_51447436/article/details/125573273
尝试一： pip install protobuf==3.19.0

提示错误：paddlepaddle 要求 protobuf>=3.20.2 。卸载 protobuf 3.19.0， pip install protobuf 换回来。

尝试二： export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python，错误：

仔细看错误提示，尝试三：（先退出shell 再进） pip install protobuf==3.20.3， 错误：
