[Informative] Having trouble with OpenGL in miniconda environment (Ubuntu 22)

[raminjafary]

Hello

if you have GPU on your machine and you are having trouble to run the project on Ubuntu 22 or higher. Run the following commands:

1. sudo apt-get install libosmesa6-dev freeglut3-dev
2. sudo apt-get install libglfw3-dev libgles2-mesa-dev
3. sudo apt-get install libosmesa6
4. export PYOPENGL_PLATFORM=osmesa (important: inside conda environment)
5. conda install -c conda-forge libstdcxx-ng
6. Still not working? try conda install cmake.

No need to downgrade the Python version or any other dep versioning hack.

Hope it helps!

Thank you for your suggestion
I tried all the steps, including conda install cmake.
But I still failed, this is an error message：

What else should I do？

Did you set export PYOPENGL_PLATFORM=osmesa in your current terminal in which conda environment is activated?

[zcdliuwei]

Yes, I did everything

[zcdliuwei]

When I run your fifth step
I encountered an error:
usage: conda [-h] [-V] command ...
conda: error: unrecognized arguments: -c

So I changed the command to: conda install libstdcxx ng - c conda-forge

[raminjafary]

Yes, I did everything

Can you try this? export DISPLAY=":1"

When I run your fifth step I encountered an error: usage: conda [-h] [-V] command ... conda: error: unrecognized arguments: -c

So I changed the command to: conda install libstdcxx ng - c conda-forge

Sorry. I fixed it: conda install -c conda-forge libstdcxx-ng

If you face any issue try this one too. conda install -c conda-forge libstdcxx-ng=12

[zcdliuwei]

Still failed, I have executed all your steps from scratch
include:
conda install -c conda-forge libstdcxx-ng=12 and export DISPLAY=":1"

[PouriaSeyfi]

its working for me
Thank you @raminjafary

[raminjafary]

Still failed, I have executed all your steps from scratch include: conda install -c conda-forge libstdcxx-ng=12 and export DISPLAY=":1"

Try pip uninstall glfw and then pip install glfw and let me know if it works.

NO
I reconstructed a virtual environment according to the project requirements and executed all your commands, but in the end, the same error was reported
I will try changing to an 18.04 environment

I encountered the same problem on Ubuntu without a display, but when I tried again on a MacBook, I did not encounter the issue. So it's likely a problem with needing a screen display.

Yes, I encountered the same problem on Ubuntu 22.04 and 18.04
but it can run normally on my Mac local machine with only CPU

[Linriversluv]

I have a remote Ubuntu18.04 environment. After following all the steps above and setting headless rendering with mesa, my problem is solved.

Many thanks.

I'm wondering if this method can help solve the issue I encountered on a remote Ubuntu18.04 environment. The problem occurred on Ubuntu18.04 and I followed these steps, but unfortunately they did not resolve the issue.
The error message is as follows:

Update:

I got it working. I re-ran the 4th command, this time paying attention to the instructions. export PYOPENGL_PLATFORM=osmesa (important: inside conda environment) (I must not have run it from inside conda the first time, hmmm. Or else I ran it from inside conda but not from within the virtual environment.) So now it works, except for the window size; the animation window is only partially visible on my Chromebook screen. Any ideas off-hand how to resize it? If not, I'll slide it over to a second screen when I get to my desk.)

My error message: "miniconda3/envs/animated_drawings/lib/python3.8/site-packages/OpenGL/contextdata.py", line 40, in getContext raise error.Error( OpenGL.error.Error: Attempt to retrieve context when no valid context

This doesn't seem to have been the problem: animated-drawings 0.0.0 requires glfw==2.5.5, but you have glfw 2.5.9 which is incompatible

I've run all the suggested conda install -c commands and export DISPLAY=":1"

I run all the instructions above but still get errors with my CentOS7 system (headless rendering):

Can anyone helps please? Thank you in advance.

@yuleiqin Did you figure it out? I've only looked at the mvc folder and when I ran into an error I resolved it by setting the USE_MESA flag to true. Had you already done that?

Just to rule out that what worked for me isn't working for you @laughxing @howardgriffin @yuleiqin #169

I solve it ，you can try
1
In mesa_view.py add
os.environ['MUJOCO_GL'] = "osmesa"
2
python3 -m pip install PyOpenGL_accelerate
apt-get update && apt-get install ffmpeg libsm6 libxext6 -y
apt-get install -y python3-opengl
apt-get install -y libosmesa6
3
In export_gif_example.yaml or any /mvc/ *.yaml
view:
USE_MESA: True

like a charm, thanks
