I am guessing your VTK dependency is because of PyVista right? Are you using VTK explicitly in some place? I think @akaszynski can weigh in better than anybody here. I know that VTK (as of released packages - i.e. not beta versions or release candidates) is not yet supported on Python 3.10 and they have some PyVista wheels for this specific case.. He'll probably have more info than anyone else.

Indeed, we do not use vtk directly, only through PyVista.
So what you are saying is that when using pyvista on Python 3.10 we cannot simply pip install?

Here the problem is not about Python 3.10, but when using vtk==9.1.0 for Pythons 3.7 to 3.9, where we get a memory error on Windows, although I could not replicate the issue locally.
I am guessing it has something to do with the specific windows installation of the github runners.

No, what I meant was that @akaszynski provided some specific VTK wheels for 9.1.0 and Python 3.10 in the PyVista project, as far as I am aware of. Follow the link: pyvista/pyvista#2064

I am seeing though you are having problems with other Python versions now... The output on the runners is limited though. Are you getting more info locally? Or does it work just fine? Try running everything from a clean virtual env. Maybe that gives you more info on the error. Though I am sure you must have tried it already.

This issue occurs on Windows when using the OSMesa opengl on windows. This shouldn't be an issue on linux.

I'm going to have to review and improve patch this.

We are using a pyvista github action to prepare the headless display in our CI. (pyvista/setup-headless-display-action@v1)
For anyone else other than Alex, this indeed means this script is used which installs a MesaOpenGL opengl32_mingw_64.dll for rendering.

Hi @akaszynski, any updates on this issue?

Hi @akaszynski, any updates on this issue?

On my (growing) todo list.

Fix was simply to install vtk<=9.1 for windows. There's an issue with OSMesa for VTK on Windows with vtk>=9.1.0 and this is very rarely used by users (batch processing is on linux typically), so I see no issue with just installing the older version until this is fixed upstream.

Identified the minimum reproducible error:
pyvista/pyvista#3185

Tried using the same trick for doctest, yet it does not work for Python 3.10 (see here).
Keeping the skip of doctest for plot_contour for now.
