Installation issue in Python 3.12.*

[LeiAstro]

Hi there,

Thank you for maintaining KLLR! I’m hoping to use it in a Python 3.12.2 environment. However, when I run "pip install kllr" I encounter an error message related to the deprecated sklearn package on PyPI (which has been replaced by scikit-learn), and the installation fails. I tried setting
"export SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True" as suggested in some older workarounds, but unfortunately, it still doesn’t resolve the issue in Python 3.12.
It looks like:
(1) KLLR depends on Python 3.5–3.9 in its metadata (so 3.12 might be unsupported by default).
(2) KLLR lists sklearn as a dependency instead of scikit-learn, which pip now blocks for Python 3.12+.

Please update KLLR’s dependencies and/or setup.py to replace sklearn with scikit-learn and add Python 3.12 support. That would help the package remain compatible with more recent environments.
Thank you very much!
