Hi, I am just reading the original Muzero paper and find one detail that keeps me confused. Can I discuss it here?
In the paper, authors said:
We use a discrete support set of size 601 with one support for every integer between โ300 and 300.
I wonder why they choose this support set? Does it have to do with the specific game environment? If I got another game environment other than Atari, (e.g, a game with a maximum reward of 10 at the end of the game). how should I choose the support set?

I noticed that in the requirements.txt file ray 1.13.0 is given. But the code is not compatible with this version, notable during training here:
ray.wait(workers, len(workers))
wait() only accepts one positional parameter and even if I use ray.wait(workers, num_returns=len(workers)), I get the following error:
wait() expected a list of ray.ObjectRef, got list containing <class 'ray.actor.ActorHandle'>
Still searching for a solution, but if somebody has a good idea, that would be awesome.
in main.py, there is if args.case == 'atari': from config.atari import muzero_config
,
but there's no atari.py in config folder, just classic_control.py. is this file missing?
