Apptainer : No module named 'baramFlow'

[fbob]

OS: cachyos - arch based Installation : apptainer on ~/BaramApptainer

apptainer exec ~/BaramApptainer/baram-24.2.0.sif /opt/baram/baramFlow.sh

gives me

/usr/bin/python3: Error while finding module specification for 'baramFlow.main' (ModuleNotFoundError: No module named 'baramFlow')

Same for mesh.

In my Ubuntu host machine, though the above message shows, the baramMesh and baramFlow work well. I guess that according to the environment setup in the host OS, this error shows and program can't be executed.

Can you try with bash -c command?

apptainer exec ~/BaramApptainer/baram-24.2.0.sif bash -c '/opt/baram/baramFlow.sh'

The program can't be run continously, then try run in the apptainer shell with following command.

apptainer shell ~/BaramApptainer/baram-24.2.0.sif
[baram-24.2.0] username@hostname:directory$ /opt/baram/baramMesh.sh

Thanks for the feedback. Useful info :

• OS: CachyOS (Arch based)
• Shell : zsh
• Display server protocol: Wayland (not X11)

It looks like the problem is related to the fact that I'm using Wayland isn't ? Many thanks. Francois

I think the error message is related to the OpenGL problem on your host OS. I think 'vglrun' needs to be installed in your host machine. I installed BARAM with 'vglrun' for x2go remote desktop which doesn't support native GL. The instruction about installing with vglrun is not described until yet. And I didn't test vglrun in the apptainer container yet.

Sooner or later, I will test on the hostOS with vglrun.

Download baram-24.2.0-vglrun.tar.gz and run apptainer container with following command:

apptainer exec ~/BaramApptainer/baram-24.2.0-vglrun.sif bash -c 'vglrun /opt/baram/baramFlow.sh'
