🐛 Describe the bug

Tried this out on a remote server with GPU. Ran into the well-known issue(s) with trying to render OpenAI gym (OpenGL based) while logged into an ssh connection with X11 forwarding (e.g., ssh -Y user@someserver).

To save some other people some googling, this worked surprisingly well if you add it to the beginning of muzero.py:

https://stackoverflow.com/questions/40195740/how-to-run-openai-gym-render-over-a-server

from pyvirtualdisplay import Display
display = Display(visible=1, size=(1400, 900))
display.start()

And then install the package with:

pip install pyvirtualdisplay

I was then able to manually inspect that MuZero was in fact balancing cartpole. Hope this helps someone else!
