Help！Why the screen outputs images flow of such low quality as well as with no color?

[xihangalpha]

When I set is_train=False and display=True in the code, the screen outputs the image flows with rather low quality and without color. Why? Could someone help me?

I have a similar problem.

I'm using this command to start docker:

docker run -it -p 8888:8888 -p 6006:6006 --name ai -e PASSWORD=ai -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY --device /dev/dri --device /dev/snd stefanutti/ai:1.0 bash

I'm using:

• VirtualBox Versione 5.1.22 r115126 (Qt5.6.2)
• Docker (last version from internat at this date 05/2017

It is probably due to some dependent libraries of openai universe.

I had same problem and managed it with making new virtualenv without universe.
I tried uninstalling universe from current env but it didn't work, so I assume it's not universe itself but its dependent library causing the problem.

I also created an issue on gym github repo but there's no answer yet.
openai/gym#596

Ran into exactly the same problem on Mac.

By using an older version of atari-py (0.0.21 for my case), the problem seemed to be solved.
Not only works for breakout, also other Atari games.

It is the version problem of gym.
By using pip install gym==0.10(my case) and modify environment.py :
modify: self.env = gym.make(config.env_name)
to: self.env = gym.make(config.env_name).unwrapped
It is for all games in gym
