I have the same problem. It works for me in python3.8, but not in 3.7. Strange...

Hmm, were you running python 3.7 with gym-super-mario-bros installed, then upgraded to python3.8? If so, you may need to reinstall nes-py because it has some compiled C++ elements that may need to be recompiled.

closing issue as I cannot reproduce, and believe reinstallation of nes-py is required. Please reopen if this is not the case.
