Installation from source on python 3.8 error

[natolambert]

Created a brand new python 3.8 conda environment, then tried to run from source:

(simulate-py3) Nathans-MacBook-Pro:simenv nato$ pip install -e  .

does pip install vtk work?

[natolambert]

Does not with that version, which is the root of the error. @thomwolf . Had discussed with Ed but forgot to update the issue.

[thomwolf]

is it because you have an M1?

[natolambert]

Did some follow up and yes this is because of m1. I didn't notice until now because I have been using an environment with pyqt6.

Installing from conda works, but is really not lightweight at all (adds a ton of other packages).

Looks like vtk has had a series of python installation issues, such as:

• not working with python 3.10 for first year of release of 3.10
• not working with 32 bit python

I still haven't found many people pointing at what my issue is. I feel like building from source would work, but we don't want users doing that.

[natolambert]

the reason was that vtk doesn't have python 3.8 wheels for apple silicon. Closing issue.
