i_naturalist2021

  • Description:

The iNaturalist dataset 2021 contains a total of 10,000 species. The full training dataset contains nearly 2.7M images. To make the dataset more accessible we have also created a "mini" training dataset with 50 examples per species for a total of 500K images. The full training train split overlaps with the mini split. The val set contains for each species 10 validation images (100K in total). There are a total of 500,000 test images in the public_test split (without ground-truth labels).

Split Examples
'mini' 500,000
'test' 500,000
'train' 2,686,843
'val' 100,000
