Thank you @walchko I was also able to reproduce this on a different platform so we will look into this asap.

I logged this internally as https://jira.unity3d.com/browse/MLA-2539.

Please have a look at our contribution guidelines if you choose to hunt the bug down further: https://github.com/Unity-Technologies/ml-agents/blob/main/com.unity.ml-agents/CONTRIBUTING.md

[RedTachyon]

Isn't unityagents a very old version that hasn't been updated since 2018? You probably want to install pip install mlagents unless I'm missing something

[AKemendo]

@RedTachyon Yes it is and that is the correct solution here. I confirmed internally that unityagents is fully deprecated

@walchko try:

pip install mlagents

and let us know if you have any issues.
