Hello，did you solve the problem?

[calcoloergosum]

I've encountered the same issue, and partially resolved it.

• laion_face_data/*/*_stats.json files reported many name resolution failure
  • something like: <urlopen error [Errno -3] Temporary failure in name resolution>: 9950
• While running download.sh, ping google.com reported ping: google.com: Temporary failure in name resolution.
• a fast dns resolver didn't resolve the issue.
• Lowering process count and thread count made it significantly better. (in download.sh, line 11, I changed --processes_count 16 --thread_count 128 to --processes_count 2 --thread_count 16

total   - success: 0.807 - failed to download: 0.184 - failed to resize: 0.009 - images per sec: 36 - count: 20000

• After the change, laion_face_data/*/*_stats.json looked sane.
• 80% of URL being up should be normal.
• It may be the issue of my DNS server, but I stopped digging further.

I experience the same issue.

Thanks for the tips. In my case, setting up a fast DNS server speeds up downloading significantly.
