Webb1 mars 2014 · np.dot is a generalization of matrix multiplication. In regular matrix multiplication, an (N,M)-shape matrix multiplied with a (M,P)-shaped matrix results in a (N,P)-shaped matrix. The resultant shape can be thought of as being formed by squashing the two shapes together ((N,M,M,P)) and then removing the middle numbers, M (to … Webb22 nov. 2024 · 175 1 1 gold badge 2 2 silver badges 13 13 bronze badges 4 The parameters of hidden_inputs = numpy.dot(self.wih, inputs) don't have the correct shapes for a matrix multiplication.

Webb16 okt. 2024 · For matrix multiplication (which is what the @ operator does), you need the inner dimensions of the matrices in question to match. That is, you can multiply a 20 x 1 matrix by a 1 x 2 matrix, but not by a 2 x 1 matrix. This is not a numpy specific thing, it's just a basic fact of matrix arithmetic.

WebbSorted by: 0 The score method of the classifier object does not work the way you are trying it to.
