Sklearn pipeline onehotencoder
Webb22 feb. 2024 · OneHotEncoder Encodes categorical integer features as a one-hot numeric array. Its Transform method returns a sparse matrix if sparse=True, otherwise it returns a 2-d array. You can't cast a 2-d array (or sparse matrix) into a Pandas Series. You must create a Pandas Serie (a column in a Pandas dataFrame) for each category. http://duoduokou.com/python/27017873443010725081.html
