# torch.broadcast_tensors

torch.broadcast_tensors(*tensors) → List of Tensors

  Broadcasts the given tensors according to Broadcasting semantics.

  Parameters:

    *tensors – any number of tensors of the same type

  Warning

  More than one element of a broadcasted tensor may refer to a single memory location. As a result, in-place operations (especially ones that are vectorized) may result in incorrect behavior. If you need to write to the tensors, please clone them first.

  Example:

      >>> x = torch.arange(3).view(1, 3)
      >>> y = torch.arange(2).view(2, 1)
      >>> a, b = torch.broadcast_tensors(x, y)
      >>> a.size()
      torch.Size([2, 3])
      >>> a
      tensor([[0, 1, 2],
              [0, 1, 2]])
