fmpy.sundials not importable on MacOS Apple Silicon in version 0.3.20
After installing fmpy(0.3.20) via pip (3.9.19 , 3.10.14, 3.12.2 respectively) on my MacOS machine (Apple Silicon M1) the following error occurs when attempting to import the fmpy.sundials module:

installing sundials with brew did not resolve this
Note that this happens only in version 0.3.20
Did you install the pre-built wheel from PyPI with python -m pip install fmpy==0.3.20?
If so, can you successfully import fmpy.sundials with FMPy 0.3.19 on Apple Silicon?
Sorry for the late reply. As of today I am able to successfully import the mentioned module with both FMPy 0.3.19 and 0.3.20
It seems like this issue is reappearing since I am again not able to import the sundials package from fmpy==0.3.20

This looks exactly like the original error message. Did you install the pre-built wheel from PyPI?

Can you check if the file is actually missing? Can you reproduce the problem with other versions of FMPy and Python?
Thanks for the fast reply. Yes the file is actually missing.
As stated originally this is exclusive to fmpy 0.3.20 on at least (3.9.19 , 3.10.14, 3.12.2 respectively) on my MacOS machine (Apple Silicon M1) and sometimes it stops complaining.
As a quick fix, can you try to rename the folder <PathToEnv>/lib/python3.12/site-packages/fmpy/sundials/x86_64-darwin/ to <PathToEnv>/lib/python3.12/site-packages/fmpy/sundials/aarch64-darwin/?
Yes that worked for me. Thanks for suggesting the quick fix, I'd still keep the issue open though
Hello! I am having exactly the same issue now (as well, only for 0.3.2). Any updates on this bug? Thank you!!
