torch.broadcast_tensors

torch.broadcast_tensors(*tensors) → List of Tensors[source]

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]])
