protobuf dependency #5915

Closed AzizRourou closed 1 year ago

AzizRourou commented 1 year ago

Problem :

On MacOS (13.3.1), after cloning the repo and following the "Advanced Local Installation for Development", when executing "mlagents-learn" for the first time, an error occur. The Terminal console responds with a traceback followed by : "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 If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

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

So I downgraded from protobuf 4.22.1 to protobuf 3.20.0.
