torch.Tensor.stride
Tensor.stride(dim) -> tuple or int
Returns the stride of "self" tensor.
Stride is the jump necessary to go from one element to the next one
   in the specified dimension "dim". A tuple of all strides is
   returned when no argument is passed in. Otherwise, an integer value
   is returned as the stride in the particular dimension "dim".
Parameters:
      dim (int, optional) -- the desired dimension in which
      stride is required
Example:
  >>> x = torch.tensor([[1, 2, 3, 4, 5], [6, 7, 8, 9, 10]])
  >>> x.stride()
  (5, 1)
  >>> x.stride(0)
  5
  >>> x.stride(-1)
  1
