Webbtorch.transpose¶ torch. transpose (input, dim0, dim1) → Tensor ¶ Returns a tensor that is a transposed version of input.The given dimensions dim0 and dim1 are swapped.. If input is a strided tensor then the resulting out tensor shares its underlying storage with the input tensor, so changing the content of one would change the content of the other.. If input is … Webbtorch.roll(input, shifts, dims=None) → Tensor Roll the tensor input along the given dimension (s). Elements that are shifted beyond the last position are re-introduced at the first position. If dims is None, the tensor will be flattened before rolling and then restored to the original shape. Parameters: input ( Tensor) – the input tensor. sign attached by velcro male and female end
