Hello, Thank you for the nice work. The IF has issue with n_features.

     46 def _score_samples(iforest, tree_idx, X):
---> 47     if iforest.n_features_in != X.shape[1]:
     48         raise ValueError("Number of features of the model must "
     49                          "match the input. Model n_features is {0} and "
     50                          "input n_features is {1}."
     51                          "".format(iforest.n_features_in, X.shape[1]))
     52     return -_compute_chunked_score_samples(iforest, tree_idx, X)
