torch.functional.atleast_1d

torch.functional.atleast_1d(*tensors)

返回每個輸入張量的至少一維檢視，其中零維張量將變為一維。具有一維或多維的輸入張量將按原樣返回。

引數

input (Tensor 或 Tensor 序列) – 要轉換為至少一維的張量。

返回

output (Tensor or tuple of Tensors)

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.]))
>>> torch.atleast_1d()
()
