[regression in 4.8.2] TVTK not built properly. #1302

Closed yurivict closed 5 months ago

Many examples, ex. examples/mayavi/mlab/wigner.py, fail:

$ python3.9 ./work-py39/mayavi-4.8.2/examples/mayavi/mlab/wigner.py

ImportError: TVTK not built properly. Unable to find either a directory: /usr/local/lib/python3.9/site-packages/tvtk/tvtk_classes or a file: /usr/local/lib/python3.9/site-packages/tvtk/tvtk_classes.zip with the TVTK classes.

The immediate reason is that /usr/local/lib/python3.9/site-packages/tvtk/tvtk_classes.zip isn't installed.

4.8.1 didn't have such problem.

Python-3.9 FreeBSD 14.0

Am not sure how you installed things. I just tested the following:

$ conda create -n junk python numpy
$ conda activate junk
$ pip install mayavi pyqt5

And things worked fine.
