torch.atleast_1d

torch.atleast_1d(*tensors)

傳回每個零維度輸入張量的一維視圖。 具有一個或多個維度的輸入張量會依原樣傳回。

參數

input (Tensor 或 Tensor 的 list) –

傳回

output (Tensor 或 Tensors 的元組)

範例

>>> 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.]))
