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)

IoPathFileLister

class torchdata.datapipes.iter.IoPathFileLister(root: Union[str, Sequence[str], IterDataPipe], masks: Union[str, List[str]] = '', *, pathmgr=None, handler=None)

Lists the contents of the directory at the provided root pathname or URL, and yields the full pathname or URL for each file within the directory (functional name: list_files_by_iopath).

Parameters:

• root – The root local filepath or URL directory or list of roots to list files from

• masks – Unix style filter string or string list for filtering file name(s)

• pathmgr – Custom iopath.PathManager. If not specified, a default PathManager is created.

Note

Default PathManager currently supports local file path, normal HTTP URL and OneDrive URL. S3 URL is supported only with iopath>=0.1.9.

Example:

from torchdata.datapipes.iter import IoPathFileLister

datapipe = IoPathFileLister(root=s3_url)
