ModuleNotFoundError: No module named 'pint.unit'

[lnaglecocco]

Describe the bug

When I try to use Hyperspy to load a dataset like LowLoss_raw = hs.load("EELS Spectrum Image (low-loss).dm4"), I get an error:

ModuleNotFoundError: No module named 'pint.unit'

To Reproduce

LowLoss_raw = hs.load("EELS Spectrum Image (low-loss).dm4")

Expected behavior

No error and working code (this same code worked a few months ago, I've made some changes, updated packages, and installed pymatgen since then)

Hi @lnaglecocco!

Can you try updating HyperSpy to 1.7.3 with e.g. pip install hyperspy==1.7.3 or conda install hyperspy==1.7.3 -c conda-forge? This issue was fixed in that version (see https://github.com/hyperspy/hyperspy/issues/3056).

Thanks @hakonanes
