[Question] TFRecordReader file mapping failed. #1476 - Github

WebTFRecord does not store any metadata about the data being stored inside. This file represents a sequence of (binary) strings. The format is not random access, so it is suitable for streaming large amounts of data but not suitable if fast sharding or other non-sequential access is desired. Webdatapipe – Iterable DataPipe that provides tuples of path name and tfrecord binary stream length – a nominal length of the DataPipe Note The opened file handles will be closed automatically if the default DecoderDataPipe is attached. Otherwise, user should be responsible to close file handles explicitly or let Python’s GC close them periodically.
