sorry to bother you.
Do you know how to deal with this error?

Hi @naiyisiji, I'm not the author, but I had encountered the same issue and could solve it by degrading the gym version.
I saw gym==0.21.0 or the recent version raised the error, and then I degraded it to the older version, gym==0.10.0, in my case.
I think this error seems to be raised due to the change of the gym library.

Thank you very much! This is the correct solution.
