Webtorch.flatten¶ torch. flatten (input, start_dim = 0, end_dim =-1) → Tensor ¶ Flattens input by reshaping it into a one-dimensional tensor. If start_dim or end_dim are passed, only dimensions starting with start_dim and ending with end_dim are flattened. The order of elements in input is unchanged..
