Core dumped on examples VTK Simple cone Remote Rendering

[paskino]

Running https://github.com/Kitware/trame/blob/master/examples/06_vtk/01_SimpleCone/RemoteRendering.py

cd examples/06_vtk/01_SimpleCone/
python RemoteRendering.py

results in Segmentation fault (core dumped).

To make sure it wasn't trame I ran succesfully an example without VTK.

To Reproduce

My system is a Ubuntu 24.04. I freshly installed miniforge (28/7/24).

conda create -n trame_example python
conda activate trame_example
pip install "trame>=3" trame-vtk trame-vuetify "vtk>9.1"

Most likely due to a headless system with vtk.
If X is not installed and running, you need to use vtk-egl or vtk-osmesa instead using --extra-index-url https://wheels.vtk.org/.

[paskino]

do you mean pip install vtk-egl --extra-index-url https://wheels.vtk.org ?

The system has X configured, but I am running remotely, so it may be trying to open a window and not manage?

[jourdain]

pip uninstall vtk
pip install vtk-egl --extra-index-url https://wheels.vtk.org

[paskino]

Thanks for the prompt response @jourdain , I confirm that it all works with vkt-egl
