Two things seem to play together: in BaseEstimator._validate_data() the array for y is converted from a pandas series with Int64 as dtype to a numpy array array([0, 1, 0, 1, 1], dtype=object).Then later in type_of_target (in utils/multiclass.py) that array is classed as "unknown" type.. I think the bug/place to change this is in BaseEstimator._validate_data() so that the ...
