torch.moveaxis

torch.moveaxis(input, source, destination) → Tensor

torch.movedim() 的别名

此函数与 NumPy 的 moveaxis 函数等效。

示例：

>>> t = torch.randn(3,2,1)
>>> t
tensor([[[-0.3362],
        [-0.8437]],

        [[-0.9627],
        [ 0.1727]],

        [[ 0.5173],
        [-0.1398]]])
>>> torch.moveaxis(t, 1, 0).shape
torch.Size([2, 3, 1])
>>> torch.moveaxis(t, 1, 0)
tensor([[[-0.3362],
        [-0.9627],
        [ 0.5173]],

        [[-0.8437],
        [ 0.1727],
        [-0.1398]]])
>>> torch.moveaxis(t, (1, 2), (0, 1)).shape
torch.Size([2, 1, 3])
>>> torch.moveaxis(t, (1, 2), (0, 1))
tensor([[[-0.3362, -0.9627,  0.5173]],

        [[-0.8437,  0.1727, -0.1398]]])
