Currently, importing cantera results in:

>>> import cantera
Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    import cantera
  File "/usr/lib64/python3.13/site-packages/cantera/__init__.py", line 4, in <module>
    from ._cantera import *
  File "build/python/cantera/_cantera.pyx", line 33, in init cantera._cantera
  File "build/python/cantera/_utils.pyx", line 1, in init cantera._utils
ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

A simple bump and rebuild should fix that. Alternatively, update to the latest release (bug 2332627).

Reproducible: Always
