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) Webb11 maj 2024 · Sorted by: 1. If you add print (u.shape, s.shape, vt.shape) after the SVD, you'll see that u is a 4x4 matrix, whereas np.dot (np.diag (s), vt) returns a 3x3 matrix. Hence why the dot product with u cannot be computed.
