[BUG] Incorrect reward "clipping" in Atari baseline about rl HOT 9 CLOSED

You are right! Maybe a sign transform would be necessary.
Although, in practice, are there any Atari environments with rewards smaller than +1/-1

from rl.

Good point! I didn't think at all if in practice this would actually be different.

We should have a SignReward transform then I guess.
(Another example of bad naming conventions in RL...)

@skandermoalla @albertbou92 do you guys want to code a SignTransform transform for this? I can maybe take care of it today or tomorrow, if you're not working on it atm

from rl.

I am not working on it atm. I don't mind doing the PR on the side if you want to focus on other stuff. I will take longer than today/tomorrow though.

from rl.

Not working on it atm and unlikely to do so this week. Would be great if you took it. Thanks!

Added a SignTransform in #1798

We need to adapt the scripts now I think
