Description
I have been modelling using the ames_housing dataset with the code attached in the following zip file.
Weird thing is that in a dataset with no nulls, adding a SimpleImputer along with a TargetEncoder(), several null values start to come out.
I'm not sure if I'm doing something wrong, but if using SimpleImputer with no Null values, nothing should happen. And actually I ran process separately and simpleImputer will not output any null value. But, once this Numpy array goes into TargetEncoder() it will output more than 2000 Nulls.
Why is that?
Expected Behavior
If no nulls are provided, no nulls should Output. See attached notebook, such when running the TargetEncoder by its own.
Actual Behavior
Steps to Reproduce the Problem
Refer to attached notebook with example code.
