Issue installing `ruptures` on `aeon` CI

[MatthewMiddlehurst]

Yesterday our CI started to fail when installing the package on MacOS (and Python 3.13 for all OS). We use ruptures as an optional dependency, and removing it from the installation list resolves our issue. Not sure if it is just some incompatibility with a recent setuptools/pip version as there has not been many recent changes to the repository.

AttributeError: module 'ruptures' has no attribute '__version__'

Ha weirdly enough, I’ve literally just been fighting with the exact same issue! Was just about to open a ticket myself. After digging in, it looks like the break comes from recent changes in setuptools-scm. My hacky workaround for now is to inject a version.py manually before install, e.g.:

echo 'version = "1.1.9"' src/ruptures/version.py

pip install --no-build-isolation .

Not pretty, but it gets things working until there’s an upstream fix.

[Zujiry]

We have the same problem on a private gitlab-CI building a docker image with python:3.10-alpine

[likaml]

Same here. Can someone make a wheel for Mac silicon?

[tg12]

Its not just Mac, Its to do with Python setup tools, It's cross platform, The same thing is happening to me on a Linux x86 box. This is my full fix in my Dockerfile.

git clone --branch v1.1.9 https://github.com/deepcharles/ruptures.git /tmp/ruptures && \
echo '__version__ = "1.1.9"' >> /tmp/ruptures/src/ruptures/__init__.py && \
pip install /tmp/ruptures

[thomasisensee]

Same here. There is already an issue opened at setuptools_scm in which they suggest not to use:

https://github.com/deepcharles/ruptures/blob/39a837b7e8d3e08d04d33f14749a1a39d86183d2/setup.cfg#L3

PR#353 might be a workaround.

[deepcharles]

Thanks for raising this issue I'll take a look today

[BryceBeagle]

We're also seeing this when locally building wheels on MacOS ARM laptops. This error was the reason I left this comment here yesterday, but I didn't realize at the time that this was affecting others: https://github.com/deepcharles/ruptures/pull/340#issuecomment-3198741502

Would be great to avoid wheel building entirely and just use pre-built ones. Thanks!

[swaritatresolve]

Yes!! Would love to see this issue expedited. What was the offending change? @deepcharles

[deepcharles]

Hopefully solved in #354

The problem is not super clear to me.

setuptools can't import the package as it installs it, so the line version = attr: ruptures.__version__ in setup.cfg raises an error. This has been observed in https://github.com/pypa/setuptools/issues/1724 There are several workarounds (reordering imports, pointing to original file version.py). The simplest is to simply delete the line. The correct version is still picked up during build.

However, we are in undocumented territory so I'm quite open to suggestions!! Also I'm not sure why this was not breaking before.

Please tell me if that works for you.

I will add support for Python 3.13 now

[AartGoossens]

Your fix removes the issue for me and I can now install without problems from the master branch (MacOS, docker linux/aarch64 and Python 3.13). Thanks!

[Zujiry]

It fixes the problem for us too :) Would appreciate a release 1.1.10!

[msemelman]

Same here! would it be possible to release bugfixes for the latest releases?

After pointing to "ruptures @ git+https://github.com/deepcharles/ruptures.git@master" it gets fixed.

[deepcharles]

🎉 Finally! New release! Thanks to everyone involved (shout out to @dudustri )

On a side note, I'd like to stray away from the benevolent dictator role and involve more people into ruptures. The community of users would certainly benefit from a broader and more diverse maintainer group.

I'll write a post in Discussion to think about the scope, gouvernance and future of the lib.

Cheers
