Description

I am trying to download datacomp-1b, but it seems both my downloading speed and success rate are low, even after I set num_retries to 3:

Research direction

The issue names DataComp-1B and num_retries=3 but no files or tests. Start by reproducing the download and examining the reported download, resize, success-rate, and throughput metrics; clarify the expected behavior and affected entry point before defining a fix. Done requires an agreed resolution for the low speed and failure rate.
