Failed to initialize EGL: EGL is not or could not be initialized

[yanpanlau]

Hi,

I successfully follow the README to download various universe packages and docker installation. I can download the docker images when type "sudo python random-agent.py" but i receive the following error

"failed to initialize glfw: APIUnavailable: EGL: Failed to initialize EGL: EGL is not or could not be initialized"

Can you please help me how to fix this problem?

Thanks,

Ben

Hi it seems the EGL is related to the GFLW and OpenGL. I try to install the latest version of GFLW 3.2.1 and I also managed to run their GFLW example. I am using Nvidia Titan X video card is there any special setting I need to set in order to get openAI universe to run properly?

[yanpanlau]

Hi OpenAI team, after further investigation I am pretty confident that the problem is related to the OpenGL driver. So I decided to uninstall all the NVIDIA driver and just install the minimal version of NVIDIA driver for my TITAN X. Now I have a slightly different error:

2016/12/18 19:03:46 C1218 19:03:46.72554 4545 vncgl.go:40] failed to initialize glfw: APIUnavailable: GLX: GLX extension not found

Can you please recommend which OpenGL software I should install so that I can run universe? I am using Ubuntu 14.04.

Thanks,

Ben
