python 3.12 Support

[Hecatron]

Hi,
This is in relation to the python bindings for NLopt

On pypi currently the latest version of python listed as supported is 3.10
https://pypi.org/project/nlopt/2.7.1/
what this means is if you install under python 3.11 / 3.12
it drops down to nlopt version 2.6.2 for some reason because of the way the dependencies are setup

because version 2.6.2 is an old version
it causes issues under windows - #507

I've found that manually building the sources and copying the files over for 2.7.1 works under python 3.12
I would raise a pull request to add in the additional supported python platforms, but I've not been able to find that inside this repository (if there's a different one dedicated to the python releases then please let me know)

In my case I'm trying to use this as it's a dependency of

Ok so after a bit more digging, it looks like there is a wheel built for 3.11
So this is just a 3.12 issue

• https://www.lfd.uci.edu/~gohlke/pythonlibs/#nlopt
• https://download.lfd.uci.edu/pythonlibs/archived/nlopt-2.7.1-cp311-cp311-win_amd64.whl

I did try force installing it

pip install --target C:\Python312\Lib\site-packages --no-deps --python-version 3.11 https://download.lfd.uci.edu/pythonlibs/archived/nlopt-2.7.1-cp311-cp311-win_amd64.whl

But this lead to another issue of

ModuleNotFoundError: No module named 'imp'

It turns out 3.12 dropped the imp module

so for now I've just dropped back to python 3.11

This sounds more like an issue with the packaging. Would assume this is more relevant for the repo linked to the nlopt pypi package: https://github.com/DanielBok/nlopt-python
