WebOneHotEncoder Encode categorical integer features using a one-hot aka one-of-K scheme. The input to this transformer should be a matrix of integers, denoting the values taken on by categorical (discrete) features. The output will be a sparse matrix where each column corresponds to one possible value of one feature. Web1) Input contains NaN. 2) ValueError: Number of features of the model must match the input.
