list_dps

torchdata.dataloader2.graph.list_dps(graph: Dict[int, Tuple[Union[IterDataPipe, MapDataPipe], Dict[int, Tuple[Union[IterDataPipe, MapDataPipe], DataPipeGraph]]]], exclude_dps: Optional[Union[IterDataPipe, MapDataPipe, List[Union[IterDataPipe, MapDataPipe]]]] = None) → List[Union[IterDataPipe, MapDataPipe]]

Given the graph of DataPipe generated by traverse_dps function, return a list of all DataPipe instances without duplication. If exclude_dps is provided, the provided DataPipes and their predecessors will be ignored.

Note

• The returned list is in the order of breadth first search of the graph
