torch.atleast_3d
- torch.atleast_3d(*tensors)[源代码]
-
返回每个输入张量的三维视图,即使其维度为零也依然如此。具有三个或更多维度的输入张量将保持不变。
示例
>>> x = torch.tensor(0.5) >>> x tensor(0.5000) >>> torch.atleast_3d(x) tensor([[[0.5000]]]) >>> y = torch.arange(4).view(2, 2) >>> y tensor([[0, 1], [2, 3]]) >>> torch.atleast_3d(y) tensor([[[0], [1]], [[2], [3]]]) >>> x = torch.tensor(1).view(1, 1, 1) >>> x tensor([[[1]]]) >>> torch.atleast_3d(x) tensor([[[1]]]) >>> x = torch.tensor(0.5) >>> y = torch.tensor(1.0) >>> torch.atleast_3d((x, y)) (tensor([[[0.5000]]]), tensor([[[1.]]]))
