Trouble in pip installing vtk-osmesa

Support
1

I’ve been using vtk-osmesa installed with pip as pip install --extra-index-url https://wheels.vtk.org vtk-osmesa,
following this post: Status Update: VTK Python Wheels - Announcements - VTK

OS: “Rocky Linux 8.6 (Green Obsidian)”
$ python --version is Python 3.12.4

This times, pip install fails:

$ pip install --extra-index-url https://wheels.vtk.org vtk-osmesa
Looking in indexes: https://pypi.org/simple, https://wheels.vtk.org

I grabbed .whl from https://gitlab.kitware.com/vtk/vtk/-/packages/483 and my problem was fixed.
But I’m happy if simple pip install comes back.

Thanks in advance.

Hello @natsu_mizu

That is outdated. Please see latest information at Status Update: Runtime OpenGL render window selection in VTK

There is no longer a need to download a separate package for osmesa support because it is built into the vtk package.
