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。 Web本文将使用pytorch这个丹炉，介绍如何联合读取多个原材料，而不是从新制作原材料和标签。. class ConcatDataset (Dataset): """ Dataset to concatenate multiple datasets. Purpose: useful to assemble different existing datasets, possibly large-scale datasets as the concatenation operation is done in an on-the-fly ...
torch.cumsum — PyTorch 2.0 documentation
WebJun 24, 2024 · In PyTorch, there is torch.cumsum, which can be thought of as a special case of scan. Specifically, cumsum is tied to the addition operator, whereas in TensorFlow or Theano, scan can be used with any binary operator (passed in as a function), not just addition.
