Cumsum pytorch
WebSep 16, 2024 · Explanation: By applying cumsum () row-wise over selectors, we compute for each unmasked element in a the target column number it should be copied to in the output tensor. Then, scatter () performs a row-wise scattering of a 's elements to these computed target locations. WebApr 12, 2024 · torch.cumsum()函数用于对输入张量进行累加和操作,返回一个新的张量,其中每个元素都是原张量中对应位置及之前所有元素的累加和。 其语法为: torch.cumsum(input, dim, dtype=None) -> Tensor 其中,参数的含义如下: input:输入张量。; dim:沿着哪个维度进行累加和操作。; dtype:输出张量的数据类型。
