WebJan 22, 2024 · StackingClassifier.fit only has a sample_weights parameter, but it then passes those weights to every base learner, which is not what you've asked for. Anyway, that also breaks, with the error you reported, because your base learner is actually a pipeline, and pipelines don't take sample_weights directly. http://rasbt.github.io/mlxtend/user_guide/classifier/StackingCVClassifier/ inadequate scaffolding
