shapes (127,1) and (13,) not aligned: 1 (dim 1) != 13 (dim 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)


If for any reason you need to calculate the score using y_pred then take a look at sklearn.metrics module.
