I want to train a model for a wide variety of classes. So, I would like to get an ImageNet 21k. Where is it possible to get it (besides the official web-site as they are not very responsive)?


  • What difficulties are you having with image-net.org's website downloads?

    The download of the imagenet dataset form the downloads is not available until you submit an application for registration. The main trouble is that my colleague submitted it in January, still haven't got it.

  • Probably, the way to go is to download the images URLs and then get the images by URLs. Though it is important to remember that many images may have been removed.

    It looks like this is no longer an option. Do you know how can I obtain this dataset now?

The only place I found where it is possible to actually download full ImageNet: https://academictorrents.com/details/564a77c1e1119da199ff32622a1609431b9f1c47. All other places where I looked either provide just a small portion of it or have broken links, even image-net.org.


It seems only winter21_whole.tar.gz is available at the official site, instead fall11_whole.tar is no longer possible other than that mentioned by @Lissanro Rayen.

A preprocessing script is given here.


To elaborate on what @MeadowMuffins wrote

check the article " ImageNet-21K Pretraining for the Masses" for more details about how to pretrain on this dataset, it's more complicated than regular ImageNet1K, but pretrain quality is much (much) better. https://github.com/Alibaba-MIIL/ImageNet21K
