(functional name: ``read_from_stream``). Args: datapipe: Iterable DataPipe provides label/URL and byte stream chunk: Number of bytes to be read from stream per iteration. If ``None``, all bytes will be read until the EOF. Example: >>> # xdoctest: +SKIP >>> from torchdata.datapipes.iter import IterableWrapper, StreamReader >>> from io import StringIO >>> dp = IterableWrapper([("alphabet", StringIO("abcde"))]) >>> list(StreamReader(dp, chunk=1)) [('alphabet', 'a'), ('alphabet', 'b'), ('alphabet', 'c'), ('alphabet', 'd'), ('alphabet', 'e')] NdatapipechunkcCs||_||_dSN)r r )selfr r r `/var/www/vscode/kcb/lib/python3.10/site-packages/torch/utils/data/datapipes/iter/streamreader.py__init__!s z!StreamReaderIterDataPipe.__init__returnccs>|jD]\}} ||j}|s|n||fVq qdSr )r readr close)r furlstreamdr r r__iter__'s  z!StreamReaderIterDataPipe.__iter__r )__name__ __module__ __qualname____doc__rtuplestrrrintrrbytesrr r r rr s N)collections.abcriortypingr%torch.utils.data.datapipes._decoratorr#torch.utils.data.datapipes.datapiper__all__rrrrr r r rs    "
