[Informative] [solved] 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：

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

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

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:
