Assume the ml-agents repository is checked out to a folder named $MLAGENTS_ROOT. Whenever you change the fields of a custom message, you must run `$MLAGENTS_ROOT/protobuf-definitions/make.bat` to create C# and Python files corresponding to the new message. Follow the directions in [this file](../protobuf-definitions/README.md) for guidance. After running `$MLAGENTS_ROOT/protobuf-definitions/make.bat`, reinstall the Python package by running `pip install $MLAGENTS_ROOT/ml-agents` and make sure your Unity project is using the newly-generated version of `$MLAGENTS_ROOT/UnitySDK`.
