Web6 mrt. 2024 · The np.multiply (x1, x2) method of the NumPy library of Python takes two matrices x1 and x2 as input, performs element-wise multiplication on input, and returns the resultant matrix as input. Therefore, we need to pass the two matrices as input to the np.multiply () method to perform element-wise input. Web21 mrt. 2024 · If you want elementwise multiplication, use the multiplication operator ( * ); if you want batched matrix multiplication use torch.bmm. 7 Likes. wasiahmad (Wasi Ahmad) March 21, 2024, 10:52pm #3. torch.bmm does matrix multiplication, not element-wise multiplication, so it can’t fulfill my purpose.
