vtk.py is indeed there.
Also, I am able to "import vtk" in a Python repl.
I'm not sure why the sanity check cannot find vtk.py, then.
This sanity check issue also plagues the python-vedo package, and I
don't know how to fix it.
(However, obviously the last line of the comment is incorrect.)

I fixed this in the v2 series.
