Hi @kinalmehta

Not sure what causes this. Could you try downgrading gym to 0.21? There are several breaking Gym updates lately. If that fixes it we will look into fixing it or pinning to 0.21.

[kinalmehta]

Thanks @semitable , it worked. BTW the requirements file seems to be outdated and there are conflicting dependencies. That could be updated. The only pin required could be gym==0.21, PyYAML==5.3.1 and maybe few others. I could test and send a PR if you want.

[semitable]

I am glad it worked. Yeah, we will be happy to merge a PR if you send it! Thanks! :)
