AttributeError: module 'google.protobuf.internal.api_implementation' has no attribute '_c_module'

I just upgraded my ray to 2.3 and I am getting this error:

AttributeError: module 'google.protobuf.internal.api_implementation' has no attribute '_c_module'

When importing rllib. Any clue?

This solves the issue: !pip uninstall -y protobuf python3-protobuf
