Webb1 Answer Sorted by: 0 The score method of the classifier object does not work the way you are trying it to. You need to directly give x_test as input and that it will calculate y_pred on its own and give you the result with y_test. So, you do not need to reshape and the correct syntax would be: y = clf.score (x_test, y_test)
