I am trying to run an OpenAI Gym environment however I get the following error:
import gym
env = gym.make('Breakout-v0')

gym.error.Error: Unable to find game "Breakout", did you import Breakout with ale-import-roms?
Code works for me with gym 0.18.0 and 0.19.0 but not with 0.20.0
You may downgrade it with
pip install --upgrade gym==0.19.0
BTW: it may also need to install gym[atari] or gym[all] to have all elements to work.
Base on information in Release Note for 0.21.0 (which is not ready on pip but you can install from GitHub) there was some change in ALE (Arcade Learning Environment) and it made all problem but it is fixed in 0.21.0.
-The old Atari entry point that was broken with the last release and the upgrade to ALE-Py is fixed
But new gym[atari] not installs ROMs and you will need to use module AutoROM
-pip install gym[atari] no longer distributes Atari ROMs that the ALE (the Atari emulator used) needs to run the various games. The easiest way to install ROMs into the ALE has been to use AutoROM.
EDIT:
Version 0.21.0 from GitHub works for me after installing
(it may need program git for it)
pip install --upgrade git+https://github.com/openai/gym
pip install autorom
AutoRom
pip install --upgrade gym[atari]
AutoRom runs program which asks if you have license for ROMs and install ROMs in AutoROM/roms but I didn't have to move ROMs to other place.
AutoROM will download the Atari 2600 ROMs.
They will be installed to:
/usr/local/lib/python3.8/dist-packages/AutoROM/roms
Existing ROMs will be overwritten.
I own a license to these Atari 2600 ROMs.
I agree to not distribute these ROMs and wish to proceed: [Y/n]:
