Unit 3 - SpaceInvaders ROM

[lipeeeee]

When trying to run: !python train.py --algo dqn --env SpaceInvadersNoFrameskip-v4 -f logs/ to train the model I get an error from gym saying It cant get the rom, here is the traceback:

gym.error.Error: We're Unable to find the game "SpaceInvaders". Note: Gym no longer distributes ROMs. If you own a license to use the necessary ROMs for research purposes you can download them via `pip install gym[accept-rom-license]`. Otherwise, you should try importing "SpaceInvaders" via the command `ale-import-roms`. If you believe this is a mistake perhaps your copy of "SpaceInvaders" is unsupported. To check if this is the case try providing the environment variable `PYTHONWARNINGS=default::ImportWarning:ale_py.roms`.

I have ran !pip install gym[atari] to try and overcome this but every requirement has already been satisfied.

problem was fixed by installing both gym[accept-rom-license] and gym[atari] before running the training code block
