Installing rendering dependencies doesn't fix "go_vncdriver was installed without OpenGL support" error.

[TomSil]

I was trying to run a file called demo.py:

import gym
import universe  # register the universe environments

env = gym.make('flashgames.DuskDrive-v0')
env.configure(remotes=1)  # automatically creates a local docker container
observation_n = env.reset()

while True:
  action_n = [[('KeyEvent', 'ArrowUp', True)] for ob in observation_n]  # your agent here
  observation_n, reward_n, done_n, info = env.step(action_n)
  env.render()

But I got the error message: go_vncdriver was installed without OpenGL support. See https://github.com/openai/go-vncdriver for details on how debug.

I then ran the code under the installation heading of this repository and reinstalled go-vncdriver, but the bug persists.

Anyone know why this might be?

Some things that might help:

• When I try and search for libx... files on my Ubuntu hard drive I can't find them. -This is the error report:

Thanks for any help

I ran into a similar error and managed to get it working by deleting the following folders

• ~/.local/lib/python2.7/site-packages/go_vncdriver
• ~/.local/lib/python2.7/site-packages/go_vncdriver-0.4.19.dist-info

Not very familiar with Python, but I think what is happening is when you install the gym dependency, it is pulling in a different version of the go_vncdriver package than the one you built with OpenGL support.

Anyways, deleting those 2 folders got it working for me.

Thanks for the response beolson, I will try it when I get time.

@TomSil @beolson did you find any fix for the problem?

I uninstalled, then reinstalled the VNC driver using these directions: https://github.com/openai/go-vncdriver Note that you have to reinstall the driver after you get the new dependencies, not before. Simply adding the dependencies afterwards does not work.

Thank beolson , It work with me, I use Python3. After setup go-vncdriver, and go /python3.5/site-packages and do as you talk.

I can't resolve this problem after delete these two floders. There exists error:ModuleNotFoundError: No module named 'go_vncdriver'
