INFO: pip is looking at multiple versions of nes-py to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install nes-py and nes-py==8.1.2 because these package versions have conflicting dependencies.

The conflict is caused by:
nes-py 8.1.2 depends on pyglet>=1.5.5
gym 0.18.0 depends on pyglet<=1.5.0 and >=1.4.0
nes-py 8.1.2 depends on pyglet>=1.5.5
gym 0.17.3 depends on pyglet<=1.5.0 and >=1.4.0
nes-py 8.1.2 depends on pyglet>=1.5.5
gym 0.17.2 depends on pyglet<=1.5.0 and >=1.4.0

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
