torch.broadcast_to

torch.broadcast_to(input, shape) → Tensor

Broadcasts input to the shape shape. Equivalent to calling input.expand(shape). See expand() for details.

Parameters:

• input (Tensor) – the input tensor.

• shape (list, tuple, or torch.Size) – the new shape.

Example:

>>> x = torch.tensor([1, 2, 3])
>>> torch.broadcast_to(x, (3, 3))
tensor([[1, 2, 3],
        [1, 2, 3],
        [1, 2, 3]])
