Hello, I would like to use the BaggingClassifier whose base estimator is a pipeline with multiple transformations including a DataFrameMapper from sklearn_pandas. I am getting an error during the fitting the DataFrameMapper as the first step of the BaggingClassifier is to convert the DataFrame to a
