Browser: Chrome

Creating env for "Breakout" game from OpenAI Gym is giving problem in Googlw colab. Following is the error message that pops up.

Note: This problem seems to be a recent issue. It was a working code till 2 days back and suddenly started giving problems.

It seems this is a general issue with Colab+gym, I fail to create the pong environment, with the same code that worked flawlessly on Saturday.

Found a fix. Go to http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html and download the .rar file with the roms. Extract that .rar file on your local machine. There are 2 zip files in the extracted folder. Then upload those 2 zip files to you colab project.. inside your colab notebook run the following from google.colab import files uploaded = files.upload()

This will give you a button to browse your local machine. Upload those 2 zip files.

Then in you colab notebook run the following !python -m atari_py.import_roms .

Don't forget the . at the end. Then you can run atari gym.

I was also experiencing the same problem and, based on the previous answers, I wrote this short script to be used in colab. I hope someone finds it useful.

! wget http://www.atarimania.com/roms/Roms.rar
! mkdir /content/ROM/
! unrar e /content/Roms.rar /content/ROM/
! python -m atari_py.import_roms /content/ROM/

It's now possible to install Gym along with the ROMs like this:

pip install gym[atari,accept-rom-license]

This installs the autorom package, which provides the AutoROM command, and runs this command with the --accept-rom-license option. AutoROM downloads the ROMs and puts them in the right folders, so everything just works again, but now if Atari decides to sue someone for using their copyrighted ROMs, it will be you, not OpenAI (I'm not a lawyer, though!). 😆

Just copy and Run.

!wget http://www.atarimania.com/roms/Roms.rar
!unrar x /content/Roms.rar /content
!python -m atari_py.import_roms .

@0x15F9 You have no idea how many times I have come back to and used your solution! :heart: Quite a lifesaver! :smile: Thanks a lot.
