AutoROM automatically installs Atari ROM files for ALE-Py (which Gymnasium Depends on) and multi-agent-ALE (which PettingZoo depends on, but will replaced by ALE-Py in the future).

AutoROM automatically downloads the needed Atari ROMs from ROM hosting websites into the ALE-Py folder and Multi-Agent-ALE-py folder in a very simple manner:

pip install autorom
AutoROM

To specify a specific installation directory for your ROMs, use the --install-dir command line flag.

AutoROM --install-dir /path/to/install

This will install ROMs at "/path/to/install/ROM/".

Furthermore, you can accept the license agreement from the command-line with:

AutoROM --accept-license

OR when you are installing the Python package by specifying the extra accept-rom-license:

pip install "autorom[accept-rom-license]"

This command would download the ROMs during installation and make them immediately discoverable to ale-py.

Packaging

AutoROM requires that you package it as a source distribution. We have a special script to build all our source distributions, i.e., ./scripts/build-dist.sh. The resulting source distributions will be located in dist/. You can directly install this with pip even including the extra accept-rom-license. For example,

pip install --find-links dist/ --no-cache-dir AutoROM[accept-rom-license]
