torch.atleast_1d

torch.atleast_1d(*tensors)

返回每个零维输入张量的一维视图。具有一维或多维的输入张量按原样返回。

参数

input (Tensor 或 Tensor 列表) –

返回

output (Tensor 或 Tensor 元组)

示例

>>> x = torch.arange(2)
>>> x
tensor([0, 1])
>>> torch.atleast_1d(x)
tensor([0, 1])
>>> x = torch.tensor(1.)
>>> x
tensor(1.)
>>> torch.atleast_1d(x)
tensor([1.])
>>> x = torch.tensor(0.5)
>>> y = torch.tensor(1.)
>>> torch.atleast_1d((x, y))
(tensor([0.5000]), tensor([1.]))
