VTK 8.1.2 (https://pypi.org/project/vtk/#files)
in Anaconda with Python 3.7 is crashing. Tested on Windows 10.
This can be shown in a very simple way just install
pip install vtk
and then run one of the Python examples e.g. https://vtk.org/Wiki/VTK/Examples/Python/Cylinder
python vtk_cylinder.py
And you will see a window appearing and disappearing very fast (crashing).
Seems like a major issue to me.
Let me know if there is an alternative installation with Anaconda and Py3.7.
Thanks!
