Will column reordering following ColumnTransformer and OneHotEncoder affect model?
If you are training a fresh model (no transfer learning), columns order should not be a problem.
I have used skikit-learn ColumnTransformer and OneHotEncoder to encode a dataframe containing categorical and continuous data (I did not use OneHotEncoder on the continuous data) but this has completely reordered the columns and removed the names.  Can I use this reordered array to develop a model or will I need to reorder them back to the original order so I can interpret the data later?
