Summary: Fixes pytorch#1013 ## Changes - Simplify the control flow of prefetcher - Delay Exception raised from thread worker to main thread in `__iter__` - Stop prefetching whenever Exception is received - As long as `stop_iteration` is not turned on or `buffer` is not empty, continue yielding data from `__iter__`. - Add serialization test - Add `PinMemory` DataPipe - `is_replciable() -> False` to keep it in the main process - Add unit tests - Update `test_proto_multi_rs.py` to `test_mprs.py` Pull Request resolved: pytorch#1014 Reviewed By: NivekT Differential Revision: D43329696 Pulled By: ejguan fbshipit-source-id: da4326dbe2388f4e23b9a1a3a5c43da09d29185a
