pg.event.set_allowed（[pg.KEYDOWN，pg.KEYUP，pg.QUIT]）pygame.error：视频系统未初始化

Question

Getting error in this file when running the Mario game I downloaded the code from the following link( https://github.com/Ja1r0/DQN-play-SuperMario ) when trying to run the file super_mario.py, I am getting this above error(pygame.error video system not initialized).

I am using ubuntu 18.04 widget in windows10.

p_name = platform.system()
print(p_name)

You said you're using [the] ubuntu 18.04 widget in windows10 (I guess you're talking about the Windows Subsystem for Linux), which does not come with a video display. It's console only, unless you install an X-server like eg xming.

The error video system not initialized tells you exactly that: there's no video system that could draw a window avaiable.

So you could either try to install an X-server or run your code from within your Windows 10 installation, not the WSL.
