torch.atleast_2d#

torch.atleast_2d(*tensors)[source]#

Returns a 2-dimensional view of each input tensor with zero dimensions. Input tensors with two or more dimensions are returned as-is.

Parameters

input (Tensor or list of Tensors) –

Returns

output (Tensor or tuple of Tensors)

Example:

>>> x = torch.tensor(1.)
>>> x
tensor(1.)
>>> torch.atleast_2d(x)
tensor([[1.]])
>>> x = torch.arange(4).view(2, 2)
>>> x
tensor([[0, 1],
        [2, 3]])
>>> torch.atleast_2d(x)
tensor([[0, 1],
        [2, 3]])
>>> x = torch.tensor(0.5)
>>> y = torch.tensor(1.)
>>> torch.atleast_2d((x, y))
(tensor([[0.5000]]), tensor([[1.]]))
