Execution fails after genomes get born

[SoftwareGuy]

Blast from the past, huh?

I tried to get this working again since I wanted to stream a bot learning SMB with Python 3.6 and Kubuntu 18.04 last weekend and didn't get very far. Everything seemed to be working until I got up to running python3 mario.py. The GUI appeared, I clicked Start Run and then.... nothing.

I got a lot of console prints, saying gen 0 genome X was born. Waited 10 minutes, no progress.

Would you have any clues as to why this isn't working as intended? FCEUX is installed, there's no Gym errors, Python seems happy.

I did try to inject some debug code into nes_env.py (some logging code) but it didn't fire for some reason. It just seems that it breaks after the genomes are created.
