unable to view agent's environment through vnc => persisting docker images?

[a1noack]

I know there are a couple of other github issues describing similar problems, but I was unable to resolve my problem with their advice. (Or maybe I simply didn't follow their advice correctly.. I'm not sure. I'm new to all of this.)

My problem is I can't view my agent's environment through VNC using open vnc://localhost:5900

When I run the train.py file from the universe-starter-agent directory, everything appears to work fine. The tensorboard screen at http://localhost:12345 seems to be very active.
However, when I attempted to see the agent's environment through VNC by executing the mac terminal command open vnc://localhost:5900 (I also tried port numbers 5901, 5902, etc.), I was greeted with an error message saying "You cannot control your own screen." When I tried to open through port 5900 and was greeted with the error message "Connection failed to 'localhost'" when I tried any of the other ports (5901-590x).

Use `tmux attach -t a3c` to watch process output
Use `tmux kill-session -t a3c` to kill the job
Point your browser to http://localhost:12345 to see Tensorboard

Have you tried going to localhost:15900/viewer/?password=openai in your browser?

[MrDadaGuy]

I have this same issue, and following @dtcarls comment, gave me a screen which just shows

Disconnect timeout  

Otherwise it's clearly still running but I just can't connect to the VNC to see. I'm on Ubuntu 16.04 -- and I will say that some of the flash games do pop the VNC window as expected, but Pong isn't doing so.

Thanks,

Update: It was working on a different port: http://localhost:15901/viewer/?password=openai
