Publish pre-compiled wheels to PyPI

[janosh]

didn't find any previous issue on this but apologies if this was discussed before

are there are blockers (technical or development time) for publishing pre-compiled wheels for phono3py to PyPI? would be great to be able to install with pip/uv

The wheel packaging was not easy and stressful to me from the experience of providing wheels of phonopy (not available now) and spglib (maintained by @LecrisUT now :)). I don't know now, but I thought it was not easy before because of lapacke that was not very popular before.

there's a very nice project directly from the python packaging authority PyPA) https://github.com/pypa/cibuildwheel which handles a lot of the platform-specific complexity of building wheels for every OS and Python version. i've used it on a few projects and had good experiences. i don't know if it handles all the needs of phono3py but if it wasn't tried yet, probably worth a shot

Thanks, @janosh! I used it a long time ago, but back then, it would sometimes stop working unexpectedly for reasons I couldn't figure out. I often spent a day or more troubleshooting since I didn’t fully understand how it worked. Eventually, I decided, 'This isn’t really my job,' and let it go.

Since users sometimes express complaints, and software development continues to be unfairly undervalued in academia, I need to be careful not to exhaust myself to avoid losing the passion to continue scientific software development.

Lapacke is a bit tricky and most likely I can't make it performant, but I can port the spglib build system here. I have one project to attend to this week, but I can add this ond to my todo for next week. @atztogo all ok sith refactoring the build system here?

Sure, thanks. But please don't feel too obligated.

No worries, this is my bread-and-butter and my new job at Qt is also cmake oriented.

Having this would be really useful for my new atomate2 anharmonic phonons workflow

[metalcycling]

This would be great to have. We have a Ray cluster using Docker containers as nodes, and we install everything at the system level using uv pip install --system. Right now, we can't install phono3py outside of a conda environment which we want to avoid.

[metalcycling]

Also, we found a way to install phono3py using pip and/or uv.

CC=/usr/bin/gcc CXX=/usr/bin/g++ uv pip install --index-url https://pypi.anaconda.org/conda-forge/simple --extra-index-url https://pypi.org/simple phono3py phonopy h5py

[atztogo]

I made it only for linux (CIBW_SKIP: "cp39-* pp* *_i686 *musllinux*"). I am not sure if it works properly.

thanks so much @atztogo! 👍

just tried pip install phono3py and uv pip install phono3py. both worked on macOS 3.12.7 and 3.13.

probably worth leaving this open to track windows wheels?

For you maybe yes. But not for me. This is a stressful job for me.
