[BUG] Pandas and SciPy dependencies requires building

[sqr00t]

Describe the bug

The version restrictions on Pandas and SciPy are deprecated or has dependency conflicts. Restriction of SciPy <= 1.9.2 resolved to SciPy==1.6.3 for my project, which does not have a cp310 wheel. This triggers complex building of wheels for SciPy for Python 3.10.14, and a few of the build dependencies cannot be installed due to admin restrictions.

Also note that Pandas <2 will face deprecation and PyPI hosted wheels for ARM builds are mostly unavailable already (again, triggering rebuilding).

Currently, the support window for SciPy 1.9.x and Pandas <2.x.x has passed.

Additional context

Machine Info:

• M1 Pro 2021, macOS Sonoma 14.7
• Python: 3.10.14

Edit:

• Looks like maximum version of SciPy that can still be supported by glmnet_python is SciPy==1.11.4, due to reliance on scipy.empty attribute. This is an open issue for SciPy>=1.12.0
• The implied changes by this issue results in 17 tests failing, all related to Pandas. Would be best to support Pandas>2.x.x

Hi @sqr00t
Thank you very much for reporting this.
We are currently blocked from releasing the version dependency structure as long as we depend on python_glmnet.
We plan to move to sklearn for the backend by January 2025 (see: #30).
Once that's done, I believe the issues you mentioned would be resolved.
Also, it would allow users to install balance on Windows (#26), and for the copyrights to move from GPL to MIT (#16).
So many good things are expected to land in 2025.

:)

[sqr00t]

Thanks for the quick response @talgalili . This sounds great!

Is there a dev roadmap that you'd be free to link me to? Keen to contribute/ test.

[talgalili]

Thanks for the offer @sqr00t !
AFAIK, the only change that is planned is what I wrote:
"We plan to move to sklearn for the backend by January 2025"

Other than that, no major changes are planned. If you have PR you want to propose, please do so and I'll gladly give them a look.

Also, if you'd be willing to share how/what you use balance for, I'd be happy to know about it.

Cheers,
T
