Sklearn Pipeline has None estimator,Convert MissingConverter

[xesdiny]

Hi,I used the convert to translate a mutli-ouput sklearn pipeline,Struction as:

scaler and selector maybe is None

Exception result:

hummingbird.ml.exceptions.MissingConverter: Unable to find converter for model type <class 'NoneType'>.

How can I do about this case?
