Small question about gym defaults #470

Closed slerman12 closed 1 year ago

slerman12 commented 1 year ago

One of the options when running gym.make is difficulty:

env = gym.make('ALE/Breakout-v5', difficulty=0)

I noticed that this argument setting works for most tasks, but not Backgammon for example. Can I just leave difficulty blank and assume that the default will be the easiest, or is that assumption not true for some envs?

Also, unrelated question: What is the Mario Bros. that comes with Atari? Is it different from the Super Mario Bros from pip install gym-super-mario-bros==7.3.0?

Hi @slerman12, there is no default difficulty, if you don't want to specify a difficulty you should set difficulty=None (this is the default).

Although it seems there was a version of the original Mario Bros ported to the Atari 2600 we don't support this. The Super Mario Bros package you linked uses an NES emulator.
