What is this error and how to fix it (in python 3.7.6)?
It looks like this class no longer exists in VTK. It was deprecated in VTK 7 (2015) and finally removed in Oct 2017. I don’t know the replacement off-hand, but it’s probably documented in a release note or in Git.
@TJ_Corona it looks like you added the deprecation. Do you know the replacement?
I believe the replacement is
vtkOpenGLGPUVolumeRayCastMapper, but I’d defer to @ken-martin on this one.
yes that is the correct replacement
