Ok, ok. Yes. I was confused as to what you meant. I haven’t used Python much in many years, let alone on Windows, so I’m pretty rusty.

Now it’s working, my steps to reproduce:

Uninstall everything, lol

Install this: https://www.python.org/ftp/python/3.8.7/python-3.8.7-amd64.exe Grab this: https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp38-cp38-win_amd64.whl

pip3.8.exe install C:\Users\Ace\Downloads\ray-2.0.0.dev0-cp38-cp38-win_amd64.whl
pip3.8.exe install "ray[rllib]" tensorflow-gpu torch
rllib train --run PPO --env CartPole-v0

Now it works, thanks for the help! @mehrdadn
