（转）paddlepaddle安装问题protobuf package to 3.20.x or lower.

报错如下：

>>> import paddle

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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

# 先说解决方法

pip uninstall protobuf

 

pip install protobuf==3.19.0
