Dear maintainer,

your package has an autopkgtest regression with NumPy 1.26.
Hopefully relevant excerpt from the test log:

  130s         # Should no longer raise warnings, because internally we practice
  130s         # what we preach.
  130s         fit_custom = BFGS(chi_squared, [a, b])
  130s >       assert len(recwarn) == 0
  
  130s E       assert 1 == 0
  130s E        +  where 1 = len(WarningsRecorder(record=True))
