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.randn(2,2) >>> x tensor([[2.2086, 2.5165], [0.1757, 0.5194]]) >>> torch.atleast_2d(x) tensor([[2.2086, 2.5165], [0.1757, 0.5194]]) >>> x = torch.tensor(0.5) >>> y = torch.tensor(1.) >>> torch.atleast_2d((x,y)) (tensor([[0.5000]]), tensor([[1.]]))
