Description
Thanks for the great work.
I encountered the following issue while downloading the DataComp-1B dataset:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/opt/conda/envs/datacomp/lib/python3.10/multiprocessing/spawn.py", line 116, in spawn_main
exitcode = _main(fd, parent_sentinel)
File "/opt/conda/envs/datacomp/lib/python3.10/multiprocessing/spawn.py", line 126, in _main
self = reduction.pickle.load(from_parent)
File "/opt/conda/envs/datacomp/lib/python3.10/multiprocessing/synchronize.py", line 110, in __setstate__
self._semlock = _multiprocessing.SemLock._rebuild(*state)
FileNotFoundError: [Errno 2] No such file or directory

Research direction
Start by reproducing the DataComp-1B download and inspect the downloader's multiprocessing entry point; no file or test is identified in the issue. Use the traceback to investigate why the multiprocessing semaphore cannot be rebuilt, then verify that the dataset download completes without FileNotFoundError.
