pyvirtualdisplay not visible [HANDS-ON BUG] about deep-rl-class HOT 3 CLOSED

Hey there 👋 it's just a context for the gymnasium library to operate in. There's no screen which will be displayed in your browser. It's just a virtual screen system that allows us to record frames to generate a video when you push your model on the Hub.

You mean the course section is not updated like the Google colab?

Hi @simoninithomas, sorry for the delay... I got busy. Here is what I mean by course mismatch... on this "hands on" page on the hugging face site: https://huggingface.co/learn/deep-rl-course/unit1/hands-on

you say to set up using this code:

sudo apt-get update
apt install python-opengl
apt install ffmpeg
apt install xvfb
pip3 install pyvirtualdisplay

This method fails

Here on github you have the same notebook here:
https://github.com/huggingface/deep-rl-class/blob/main/notebooks/unit1/unit1.ipynb

and you say to set up using this code:

!sudo apt-get update
!sudo apt-get install -y python3-opengl
!apt install ffmpeg
!apt install xvfb
!pip3 install pyvirtualdisplay

This method works

I will proceed by using the github notebooks... but I'm guessing people that are following the course directly on huggingface are having problems and giving up

And also - thank you making this course... I have been reading the sutton book and working through the exercises... but this presentation is much more congenial and has modern hands on examples. Very great!
