Hi @clementpoiret , thank you for raising the issue. Do you happen to know what the new URLs to the data are? If you find them, you can also send us a quick PR to update them :)

I saw that mirrors were used because the original host is unreliable, so I found another mirror at https://data.brainchip.com/dataset-mirror/voc/

The issue with the original link also is that voc2012 test images are behind a login, so this would be annoying for tfds which uses this archive. The mirror I found has everything, I used this one, seems reliable and high speed.

If you are okay with this mirror I'll do a PR

Looks good to me! Thank you, you can add me as a reviewer of the PR :)

[clementpoiret]

Sounds like I don't have the rights to add specific reviewers :/

Thanks for the ping, I added myself as a reviewer!

Thank you for the PR! As it has been merged, the problem should have been fixed with the fix already available on tfds-nightly. I'm closing the bug for now, please feel free to reopen it in case the problem persists!
