Unable to import machine learning modules

[saturnv5]

Hi there,

I'm writing a script that needs to import either lightgbm or scikit-learn. Former is preferred.

I first tried adding lightgbm to requirements.txt, but got this error in the logs:

2025-09-12 23:09:50.246 ERROR (SyncWorker_3) [homeassistant.util.package] Unable to install package lightgbm: × Failed to build `lightgbm==4.6.0`
  ├─▶ The build backend returned an error

I then tried using scikit-learn instead, and got the following error:

Any idea what I'm doing wrong here?

Thanks!
