torch.Tensor.masked_scatter

Tensor.masked_scatter(mask, tensor) → Tensor

torch.Tensor.masked_scatter_() 的非原地版本。

注意

self 和 mask 输入将广播。

示例

>>> self = torch.tensor([0, 0, 0, 0, 0])
>>> mask = torch.tensor(
...     [[0, 0, 0, 1, 1], [1, 1, 0, 1, 1]],
...     dtype=torch.bool,
... )
>>> source = torch.tensor([[0, 1, 2, 3, 4], [5, 6, 7, 8, 9]])
>>> self.masked_scatter(mask, source)
tensor([[0, 0, 0, 0, 1],
        [2, 3, 0, 4, 5]])
