Description of the changes
In scikit-learn 1.6.0,
force_all_finitehas been renamed toensure_all_finite. This causes an unknown argument error in the lightgbm CI. This PR fixes the error by pinning the scikit-learn version to < 1.6.0.https://scikit-learn.org/stable/modules/generated/sklearn.utils.check_X_y.html
