Webb6 maj 2024 · It seems to be your main issue, specifically the mismatch of dimension. It can be sorted out by switching the two terms. Doing so, we can even use a simple list of floats instead of a 2-dimension ndarray, numpy will take care of the rest. This should result in 82832 single values in a (1, 82832) array. The mathematical issue is with matrix multiplication of shapes (3,1) and (3,1). That's essentially two vectors. Maybe you wanted to use the transposed matrix to do this? nm = np.dot(np.conj(b1).T, np.dot(A, b1)) dm = np.dot(np.conj(b1).T, b1) Have a look at the documentation of np.dot to see what arguments are acceptable.

Sorted by: 5. model in line model = sm.OLS (y_train,X_train [:, [0,1,2,3,4,6]]), when trained that way, assumes the input data is 6-dimensional, as the 5th column of X_train is dropped. This requires the test data (in this case X_test) to be 6-dimensional too. This is why y_pred = result.predict (X_test) didn't work because X_test … 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)
