Enable/force featuretools to use 2 or more columns to group by

Question

How to enable or force featuretools to create featuretools groupby features using 2 or more columns as group bys.

For example I have columns x, y, z

how to set groupby_primitives_options or something to get feature func(func(x) groupby y, z) ?

Answer 1

groupby_primitive_options does not currently support grouping by 2 or more columns, but you could write a custom primitive that does additional groupby operations inside the primitive function.

This may not directly apply to your situation, but in this user issue grouping by multiple columns was achieved by adding an intermediate table to the entityset.
