torch.dot
torch.dot(input, other, *, out=None) -> Tensor
Computes the dot product of two 1D tensors.
Note:
 Unlike NumPy's dot, torch.dot intentionally only supports
 computing the dot product of two 1D tensors with the same number
 of elements.

Parameters:
      * input (Tensor) -- first tensor in the dot product, must
        be 1D.
  * **other** (*Tensor*) -- second tensor in the dot product, must
    be 1D.

Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
Example:
  >>> torch.dot(torch.tensor([2, 3]), torch.tensor([2, 1]))
  tensor(7)
