OpenGL problem on ubuntu 16.04

[asimmunawar]

I installed everything according to instructions. However, I am getting the following error. I have tried everything given in #2. But nothing seems to work.

$ python3 agent_zoo/demo_race2.py

I saw this, too. Give these steps a shot: #6 (comment).

I think the steps under "Fix nvidia driver issues" should resolve what you're seeing.

[asimmunawar]

cjjeakle, thanks alot,
Followed the instructions under "Fix nvidia driver issues". It solved the problem.
So there is some problem with the default nvidia-375 driver.

[johnkelly]

Seeing this issue (same error) on Ubuntu-16.04 with the latest Nvidia driver 381.22 with 1080TI gpu. Unfortunately, the 381.22 driver is the only driver I can use with my motherboard/gpu.

[jacknlliu]

This issue still exists for me. I use Ubuntu 16.04 with Nvidia driver 375 with GTX960 GPU.

[davidljung]

Just adding from OpenGL import GLU to the beginning of the pyhon main resolved this issue for me (e.g. to the top of agent_zoo/RoboschoolHumanoidFlagrun_v0_2017may.py (- this was suggested elsewhere, I don't recall where I saw it).

[ethanluoyc]

I can confirm that @davidljung's method works for me.

[github-kk]

I added from OpenGL import GLU to the py. It works !!! Ubuntu 16.04 nvidia-381.
@davidljung Thanks :)

[lutein]

@davidljung Thanks a lot! Works on Ubuntu 16.04, GTX 1060, nvidia-390.

[chedanix]

@davidljung Thank you so much! Works on ubuntu 16.04, GTX 1080, nvidia-384

[ouyangzhuzhu]

hi~，how to add "from OpenGL import GLU" , does it like this below ? ： @davidljung
from OpenGL import GLU
if name=="main":
demo_run()

[LUKELIEM]

@davidljung's method works for me as well.

I encountered the error when running a code to record an episode of a trained model. I simply add from OpenGL import GLU to the top of the Python code creating the environment. There is no need to add it to the RoboSchool_XXX.py itself.

[PierreExeter]

@davidljung 's method worked for me, thanks a lot! On Ubuntu 18.04 GTX 1060. I just had to install the pyopengl from Anaconda
