Gymnasium no longer distributes ROMs

[RihabHashim]

hello,
Having issue to import Assult-v4 on python

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

any recommendations please?

Have you followed the message? What have you done?

if you are using gymnasium only, you can run pip install "gymnasium[all,accept-rom-license]" to download full Atari ROMs because in gymnasium version>=0.20, gymnasium doesn't distribute atari ROMs. If you are using torchrl, you can specify the version by install "gymnasium[all,accept-rom-license]==0.2x" to specify a version that satisfies the dependence of torchrl
