In estimator.py , when preprocessing is None in HyperoptEstimator, it will use a preprocessing anyway.

if preprocessing is None:
    preprocessing = components.any_preprocessing('preprocessing')

Is it possible to not use preprocessing at all?

bjkomer commented 5 years ago

yes, you can pass an empty list [] to use no preprocessing
