Once i start training, Unity window pops up and i can see the agent moving around at fast speed so everything looks ok. However, after a few seconds this error message shows up:

Can you please let me know how to fix it? Thanks!

To fix this, your action has to be an np.int32. When a random action is selected argmax generate an int64.
The solution is to cast it to int so x.astype(int).
