🐛 Describe the bug

I created new venv, then installed per the requirements. When I went to run "python muzero.py" it gave a repeating loop of ray errors.

Add an example

Minimal Reproducible Example

I just ran the command "python muzero.py"

Additional

I manually updated ray using "pip install ray --upgrade" and the warnings (and crashing) went away.

[digits122]

same error. Try this

pip uninstall ray
pip install "ray[default]"

use the newest version of ray instead of ray 1.5.2 version mentioned in requirements.lock and this problem solved.
