TypeError: cannot pickle 'Environment' object

Hello,

I have this error and I really don't know what to do. I'm new in coding so, I really need help! :-P

there is all lines in my Terminal : (THX for helping me)

I have the same problem.

That sounds to be related to PyTorch. Adding --workers 0 fixed the problem for me. Check this issue.
