[FIXED] Error when running a DQN pygame script in Google Colab

Issue

When I am running a DQN script using Pygame on Google Colab it is throwing error -

pygame.error: No available video device

I am trying to run this GitHub repo on Google Colab. pong_neural_network_live

Installed the Pygame using following code-

import os
!git clone https://github.com/ntasfi/PyGame-Learning-Environment.git
os.chdir('PyGame-Learning-Environment')
!pip install -e .
!pip install pygame
os.chdir('/content')

On trying to initialize and run the following code it

import pygame
pygame.init()
pygame.display.list_modes()

I get

error: video system not initialized

PS: I also enabled third party cookies in Google Chrome.

Solution

Colab is run in the cloud. It cannot send display to a window on your computer. So, you cannot use Pygame. Or you need some clever hacking like VNC.
