问题 I want to build an sklearn VotingClassifier ensemble out of multiple different models (Decision Tree, SVC, and a Keras Network). All of them need a different kind of data preprocessing, which is why I made a pipeline for each of them. # Define pipelines # DTC pipeline featuriser = Featuriser() dtc = DecisionTreeClassifier() dtc_pipe = Pipeline([('featuriser',featuriser),('dtc',dtc)]) # SVC pipeline scaler = TimeSeriesScalerMeanVariance(kind='constant') flattener = Flattener() svc = SVC(C =
