AssertionError when importing on M1 Mac (installed from pip)

[gayverjr]

Hello,
I pip installed numgrid in an ARM python 3.9.10 environment without any errors, however I receive the following error when I try to import the module:

import numgrid

Traceback (most recent call last):
File "", line 1, in
File "/Users/jamesrgayvert/miniforge3/lib/python3.9/site-packages/numgrid/init.py", line 44, in
assert _header_file is not None

Everything works totally fine if I install and run in a Rosetta2 environment, so there's something ARM specific happening here.

The error message looks like that in the ARM environment it does not find a matching binary distribution and falls back to a super old source distribution. The error that you see comes from a old version of Numgrid and the corresponding code that throws that error has already been removed.

What I need to find out how to do is how to build a binary distribution for the ARM environment. This is macOS, right?

[bast]

Oh the issue title says it's M1 Mac. OK I need to learn how to package a binary distribution for the M1.

I need to adapt this somehow: https://github.com/dftlibs/numgrid/blob/main/.github/workflows/package.yml#L13

[bast]

I am unsure whether this is possible on GitHub Actions: actions/runner-images#2187

But one thing I can do is to describe how you could build the Python module on M1.

Oh, somehow I missed that it wasn't grabbing a wheel; it's downloading numgrid-1.1.2, that makes a lot of sense. I just cloned the repo and pip installed from source and there were zero issues, so the good news is that it doesn't look like there's anything that needs to be fixed on your end.

As far as an automated workflow for generating the wheels goes, hopefully GitHub actions will add support soon, but for what it's worth cibuildwheel appears to (I've never used it so I can't attest to whether it would work for numgrid).

[bast]

I am glad the local build worked. I will check out cibuildwheel which I did not know about.

+1 to more prebuilt distributions, it would be nice to have some Python 3.11 support as well.

(Thanks for such a great project!)

I will create a Python 3.11 package this week. Sorry for troubles.

Almost a year later ... I finally now created packages for Python 3.10, 3.11, and 3.12.
