[vtkusers] Wheels for Python3.7 ('pip3 install vtk' fails)

[Lukas Riedel]

Hello,

being able to install the VTK library for Python into a virtual environment is really handy. However, PyPI currently lacks wheels for the most recent version 3.7 of Python. Are there any plans for a release?

The information reported by ‘pip’ is already quite confusing:

$ python3 --version
Python 3.7.1

$ python3 -m pip search vtk
vtk (8.1.1) - VTK is an open-source toolkit for 3D computer graphics, image processing, and visualization
[
]

$ python3 -m pip install vtk
Collecting vtk
Could not find a version that satisfies the requirement vtk (from versions: )
No matching distribution found for vtk

I realized there are no distributions of ‘vtk’ for Python 3.7 when looking at the files overview in PyPI, https://pypi.org/project/vtk/#files <https://pypi.org/project/vtk/#files>.

I did not find any major issues concerning the compatibility of VTK with Python 3.7. Is there a reason no wheels have been distributed yet? Is there any way one can help?

Thank you in advance!

Hi,Lukas

The current VTK in pip do not support python3.7.

Solution:
1. You can use python3.6 or 3.5, 3.4. See the supported python version in
the link https://pypi.org/project/vtk/#files
<https://pypi.org/project/vtk/#files>
2. You can build VTK source with "VTK_WRAP_PYTHON" on.

Hi Lukas,

There was a change in the Python 3.7 API that caused compatibility problems
with VTK. This has been fixed in VTK 8.1.2, which was released a few days
ago. Unfortunately I don't know the timeline for getting VTK 8.1.2 into
PyPI.

Yup, like Frank says in #2, I just built 8.1.2 on Windows last night using Python 3.7.1 (3.7.0 can't be used, https://gitlab.kitware.com/vtk/vtk/issues/17363 ). Ran our full regression suite using those and it works just fine.

To be fair, VTK 8.1.2 "mostly" works with the old Python 3.7.0 release.
What doesn't work is the vtkpython executable and embedding the
interpreter. Definitely recommend Python 3.7.1, though.

Hi,

To allow generating the wheel for python 3.7, this project would need to be
fixed/updated: https://github.com/KitwareMedical/VTKPythonPackage
