torch.sum(input, *, dtype=None) → Tensor. input テンソルのすべての要素の合計を返します。. Parameters. input（Tensor）–入力テンソル。. キーワード引数. dtype (torch.dtype, optional) – the desired data type of returned tensor.If specified, the input tensor is casted to dtype before the operation is performed. This is useful for preventing data type overflows.

torch ¶ The torch package ... Sums the product of the elements of the input operands along dimensions specified using a notation based on the Einstein summation convention. flatten. Flattens input by reshaping it into a one-dimensional tensor. flip. Reverse the order of a n-D tensor along given axis in dims.
