Web13 de jun. de 2024 · How to do dot product of two tensors. timbmg June 13, 2024, 2:43pm #1. In numpy I can do a simple matrix multiplication like this: a = numpy.arange (2*3).reshape (3,2) b = numpy.arange (2).reshape (2,1) print (a) print (b) print (a.dot (b)) However, when I am trying this with PyTorch Tensors, this does not work: WebThe numpy module of Python provides a function to perform the dot product of two arrays. If both the arrays 'a' and 'b' are 1-dimensional arrays, the dot () function performs the inner product of vectors (without complex conjugation). If both the arrays 'a' and 'b' are 2-dimensional arrays, the dot () function performs the matrix multiplication.
