June 2024 Status Update: Removing DataPipes and DataLoader V2
We are re-focusing the torchdata repo to be an iterative enhancement of torch.utils.data.DataLoader. We do not plan on continuing development or maintaining the [DataPipes] and [DataLoaderV2] solutions, and they will be removed from the torchdata repo. We’ll also be revisiting the DataPipes references in pytorch/pytorch. In release torchdata==0.8.0 (July 2024) they will be marked as deprecated, and in 0.9.0 (Oct 2024) they will be deleted. Existing users are advised to pin to torchdata==0.8.0 or an older version until they are able to migrate away. Subsequent releases will not include DataPipes or DataLoaderV2. Please reach out if you suggestions or comments (please use this issue for feedback)
traverse_dps¶
- torchdata.dataloader2.graph.traverse_dps(datapipe: Union[IterDataPipe, MapDataPipe]) Dict[int, Tuple[Union[IterDataPipe, MapDataPipe], Dict[int, Tuple[Union[IterDataPipe, MapDataPipe], DataPipeGraph]]]] ¶
Traverse the DataPipes and their attributes to extract the DataPipe graph.
This only looks into the attribute from each DataPipe that is either a DataPipe and a Python collection object such as
list
,tuple
,set
anddict
.- Parameters:
datapipe – the end DataPipe of the graph
- Returns:
A graph represented as a nested dictionary, where keys are ids of DataPipe instances and values are tuples of DataPipe instance and the sub-graph
