WebFeb 10, 2024 · The latest version of scikit-learn, v0.22, has more than 20 active contributors today. v0.22 has added some excellent features to its arsenal that provide resolutions for some major existing pain points along with some fresh features which were available in other libraries but often caused package conflicts. 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.
WebNov 26, 2024 · The documentation on sklearn for StackingClassifier says: Base estimators which will be stacked together. Each element of the list is defined as a tuple of string (i.e. name) and an estimator instance. An estimator can be set to ‘drop’ using set_params. So a correct list would look the following: http://rasbt.github.io/mlxtend/user_guide/classifier/StackingCVClassifier/
