Downgrade the protobuf package to 3.20.x or lower.

[openxbmc]

你好，请问是否可以升级JoyCaption的依赖，因为我测试protobuf==3.20.1版本可以用，但这个版本很老了，与其它插件新的依赖冲突。

我自己的环境，protobuf的版本是4.25.4，请问下你具体的冲突提示？

作者你好，首次本地反推运行后提示我：一大堆内容，核心是我看到的这句：Downgrade the protobuf package to 3.20.x or lower.之前遇到这个问题我手动降低到3.20.1就好了，如果我不降级，再运行就会提示：Couldn't build proto file into descriptor pool: duplicate file name sentencepiece_model.proto，我使用工具还真搜不到这个sentencepiece_model.proto文件。

这是首次运行后的提示：
JoyCaption
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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

更新一下：我手动升级sentencepiece不报错了，我一直以为问题出在protobuf中

抱歉，这几天忙着别的事情没有看issue，解决了就好 @openxbmc
