WebbSorted 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) Webb21 nov. 2013 · With dot the basic rule is that the last of dimension of A pairs with the 2nd-to-the-last of B. This is the same as the manual across columns, down rows method of matrix multiplication. The one that works is a (3,4) with a (4,4) resulting in a (3,4). – hpaulj.
