Hello all,
On a windows 7 64 bits computer, I installed pyhton 3.7.1.
then in a command prompt I installed vtk with the command:
> pip3 install vtk
This instaled vtk correctly as far as I can tell.
But then in python If I used the command:
> \>\>\> import vtk
I get an error ending by:
> ModuleNotFoundError: No module named ‘vtkCommonKitPython’
So obviously nothing vtk related works on that computer. Other python modules work fine.
I checked the file was present at the adress indicated, it is there, exept the python error uses a path (…)\lib(…) instead of (…)\Lib(…)
Then I tried to rediefine environment variables PATH and PYTHONPATH, but it did not solve my problem.
A couple of month ago I installed python 3.7.1 and vtk on another windows 7 64 bits computer and it worked without problem so I am a bit surprised.
I would appreciate some help / ideas.
thank you,

Python gives that error if the module failed to be opened too. I’d check that dependent libraries (e.g., `vtkCommonCore`) is in `PATH`. Cc: @jcfr

The module `vtkCommonKitPython` can be found within the wheel:
After creating a virtual env and installing `vtk` wheel using Python 64-bit, I couldn’t reproduce the problem:
