list_dps

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