(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')] Nc ||_||_yN)datapipechunk)selfr r s o/root/repos/pocs/video-evals/.venv/lib/python3.12/site-packages/torch/utils/data/datapipes/iter/streamreader.py__init__z!StreamReaderIterDataPipe.__init__ s   c#K|jD]:\}} |j|j}|s|j5||f5ywr )r readr close)r furlstreamds r__iter__z!StreamReaderIterDataPipe.__iter__$sO MM LD&KK +LLNQi  sA A r )__name__ __module__ __qualname____doc__rrrrrr s& rN) typingr%torch.utils.data.datapipes._decoratorr#torch.utils.data.datapipes.datapiper__all__strbytesrrrrr#sGE< & &'( |E#u*,=> ) r
