montagepy-2.3.0-cp311-cp311-macosx_11_0_arm64.whl contains x86_64 binary, not arm64

[thomassola]

The wheel file named macosx_11_0_arm64 for MontagePy 2.3.0 (Python 3.11) actually contains an x86_64 binary. Running file on the extracted .so confirms this:

montagepy-2.3.0-cp311-cp311-macosx_11_0_arm64.whl
MontagePy/main.cpython-311-darwin.so: Mach-O 64-bit bundle x86_64

This causes an ImportError on Apple Silicon Macs when Python is running natively as arm64. The workaround is to install and run under Rosetta (arch -x86_64), but the wheel should either contain a true arm64 binary or be relabeled as x86_64.

System: MacBook Pro M2 Pro, macOS 15 Sequoia, Python 3.11

Hi Thomas,

Thanks for your report, and you are correct. It is a broader issue affecting all macOS wheels in 2.2.0 and 2.3.0. and we are working on it.

The latest version with the fixes is available here: https://github.com/Caltech-IPAC/Montage/tree/main/python/MontagePy/built_wheels_v2.3.1

and the version you are working with can be installed with:
pip install "https://github.com/Caltech-IPAC/Montage/raw/main/python/MontagePy/built_wheels_v2.3.1/montagepy-2.3.1-cp311-cp311-macosx_11_0_arm64.whl"

We are currently working on some issues with PyPI, but when those are resolved we will update it with the correct release.
