Extracting encoded features after CatBoost I have a dataset containing numerical as well as categorical variables. 

After I've fit my dataset to a CatBoostClassifier, I want to extract the entire feature set, with the categorical variables encoded in whatever method the classifier decided to encode them. 

How can I extract the fully transformed (encoded) features? (similar to what a fit_transform method would return)
I don't believe this is possible, CatBoost does target encoding per split, so you end up with different values of encoding at different trees.

Before each split is selected in the tree (see Choosing the tree
structure), categorical features are transformed to numerical. This is
done using various statistics on combinations of categorical features
and combinations of categorical and numerical features.

However, if you just want to use the CatBoost encoding algorithm. You can use CatBoostEncoder
