kikuchipy v0.10.0 incompatible with SciPy > 1.13

[Fred-Ad]

In a new enviroonment I have : Kikuchipy 0.10.0, Python 3.12.6, Hyperspy 1.7.6

When loading a master pattern generated by EMsoft,

import kikuchipy as kp
mp = kp.load('MCoutput.h5')

I have this error :

---------------------------------------------------------------------------

It seems that scipy changed scipy.integrate.simps to scipy.integrate.simpson since 1.6, but I bet hyperspy would have change it for a while, no ?

Hi @Fred-Ad!

Indeed, HyperSpy have changed this in v2. I'm working on us supporting that version. Until then, the solution is to install scipy < 1.14, where scipy.integrate.simps is still importable.

The same problem was reported by @yuanh6 in #685 and this seemed to fix his issue.

[Fred-Ad]

For the moment I changed simps by simpson and cumtrpz by cumulative_trapezoid in Hyperspy/_signals/dielectric_function and it works.

Oh, sorry I missed this one. Thanks Hakon !

Not at all, thanks for reporting! I've made the title more descriptive and pinned the issue so that others who experience the same issue sees it.
