py37 and vtk < 9.0 works ok.
There is no vtk<9.0 for py38 and greater and vtk9 just doesn't seem to work.

Hi @thompson318 ,
Which exact version of vtk you are using for py37 and vtk < 9.0 works ok.? and for which version of Ubuntu?

Perhap vtk/python versions are the source of the issues when running python vtkoverlay_app.py SciKit-Surgery/scikit-surgerytutorial01#31

I've been messing around with trying to fix this in SciKit-Surgery/scikit-surgeryvtk#181. I've tried several versions. I'm currently thinking that we should move to vtk>9.0 and python > 3.9 for ubuntu.

Hi @thompson318

This issues has been partially solved in the coming merge of #53 as application is launching and visualising window with overlay text after adding self.vtk_overlay_window.Initialize() in common_overlay_app.py. However, the application don't close properly which will be followed in #54.

I think we keep this issue open and in the meantime, I think we can delete or archive stale branch https://github.com/SciKit-Surgery/scikit-surgeryutils/tree/49-getworkingonlinux.

Thanks

FYI.
Useful command for debugging and kill process for pytest -v -s tests/test_sksurgerytextoverlay.py

ps -ef | grep "test_*sksurgery*" | awk '{print $2}' | xargs kill

Hi @thompson318

pytest -v -s tests/test_sksurgerytextoverlay.py is working but it does not close the app properly so I need to kill the process and I realised that the 49-getworkingonlinux branch has nothing to do with the latest changes of the lib, so I think it would be good to delete or archive stale branch https://github.com/SciKit-Surgery/scikit-surgeryutils/tree/49-getworkingonlinux ?
