working with pipelines

[geoHeil]

Do you support working with pipelines where only the last step is an estimator?
Is it possible to stack them like StackingClassifier(classifiers=[pip1, pip2, pip3, pip4]

I tried this and it seems to be stuck / not continue evaluating the pipeline.

As long as it implements the fit, predict, predict_proba interface (which the pipeline does) it works. If not, please, paste here your code and we'll take a look at it. (Try with a subsample of the dataset and, once you see it works, proceed to the whole dataset).

Will do that.
