How severe does this issue affect your experience of using Ray?
- Low: It annoys or frustrates me for a moment.
I try to follow the great walkthrough article by Sven Mika in Medium to get started with Unity3D and rllib. The training for 3DBall fails with AttributeError: ‘DecisionSteps’ object has no attribute ‘group_reward’.
I am fairly well acquainted with rllib but not with Unity. Maybe the problem is very specific to my versions (Unity 2020.3.30f1 and ray 1.13.0). I guess I have to dive into the details. However, if you see that the article needs an update, that would be appreciated.
