torch.atleast_2d
- torch.atleast_2d(*tensors)[源代码]
-
返回每个输入张量的二维视图,即使其维度为零也一样。对于两个或更多维度的输入张量,则直接返回原张量。
示例:
>>> 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.]]))
