when build vtk with python3.10.12 at commit 0288764b4b on ubuntu 22.04.4, build is ok, but when import vtk in python, raise error as follows

In [1]: import vtk

Seem to work fine with Python 3.11 here.

Could be that there’s some CMake option that makes the wrappers see a header but it isn’t built?

No idea here …

Also note that the python3.10 wheel jobs works as expected: TestImplicitArrayInstanciation passes on 2024-05-02 date bump commit https://gitlab.kitware.com/vtk/vtk/-/jobs/9703610

I test it on Python3.12.3, but failed.

Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main
  File "<frozen runpy>", line 88, in _run_code

I will change to python3.11, and test it. thanks for this info.

python3.11 also has this issue.
