dependency on `quadprog`

What happened + What you expected to happen

Executing pip install hierarchicalforecast on python=3.11.6 (Mac, M2) fails building with quadprog identified as the failure. A fix for the issue is in this branch . However, it seems that the project is looking for maintainers.

Versions / Dependencies

quadprog

Reproduction script

mamba create -n nixtla python=3.11.6 -c conda-forge pip install hierarchicalforecast

Issue Severity

Medium: It is a significant difficulty but I can work around it.

It also failed on Windows 10, I checked some links but still unable to fix it. Here is the error:

Building wheels for collected packages: quadprog Building wheel for quadprog (pyproject.toml) ... error error: subprocess-exited-with-error

× Building wheel for quadprog (pyproject.toml) did not run successfully. │ exit code: 1 ╰─> [5 lines of output] running bdist_wheel running build running build_ext building 'quadprog' extension error: Microsoft Visual C++ 14.0 or greater is required.

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for quadprog Failed to build quadprog ERROR: Could not build wheels for quadprog, which is required to install pyproject.toml-based projects

I also tried to get the wheel from the pypi but it didn't have it for Python 3.11.

In case it's useful to anyone, you can use this temporary workaround in the meantime. Before installing hierarchicalforecast, first install this version of quadprog: pip install git+https://github.com/quadprog/quadprog.git@refs/pull/43/head

@hmanz thank you so much bro <3

quadprog 0.1.12 includes wheels for CPython 3.8-3.12 and for the most common operating systems. Feel free to reopen if you encounter this issue again.
