The instructions below are adapted from CoOp with some modification to add few Out-Of-Distribution datasets at the end. It appears that the official link provided may be invalid. You can download the required data from various platforms and then follow the file structure to place the corresponding data accordingly.

How to install datasets

We suggest putting all datasets under the same folder (say $DATA) to ease management and following the instructions below to organize datasets to avoid modifying the source code. The file structure looks like

$DATA/
|–– imagenet/
|–– caltech-101/
|–– oxford_pets/
|–– stanford_cars/

If you have some datasets already installed somewhere else, you can create symbolic links in $DATA/dataset_name that point to the original data to avoid duplicate download.

Datasets list:

The instructions to prepare each dataset are detailed below. To ensure reproducibility and fair comparison for future work, we provide fixed train/val/test splits for all datasets except ImageNet where the validation set is used as test set. The fixed splits are either from the original datasets (if available) or created by us.

ImageNet

  • Create a folder named imagenet/ under $DATA.
  • Create images/ under imagenet/.
  • Download the dataset from the official website and extract the training and validation sets to $DATA/imagenet/images. The directory structure should look like
imagenet/
|–– images/
|   |–– train/ # contains 1,000 folders like n01440764, n01443537, etc.
|   |–– val/
  • If you had downloaded the ImageNet dataset before, you can create symbolic links to map the training and validation sets to $DATA/imagenet/images.
  • Download the classnames.txt to $DATA/imagenet/ from this link. The class names are copied from CLIP.

Caltech101

The directory structure should look like

caltech-101/
|–– 101_ObjectCategories/
|–– split_zhou_Caltech101.json

OxfordPets

The directory structure should look like

oxford_pets/
|–– images/
|–– annotations/
|–– split_zhou_OxfordPets.json

StanfordCars

The directory structure should look like

stanford_cars/
|–– cars_test\
|–– cars_test_annos_withlabels.mat
|–– cars_train\
|–– devkit\

UCF101

  • Create a folder named ucf101/ under $DATA.
  • Download the zip file UCF-101-midframes.zip from here and extract it to $DATA/ucf101/. This zip file contains the extracted middle video frames.
  • Download split_zhou_UCF101.json from this link.

The directory structure should look like

ucf101/
|–– UCF-101-midframes/
|–– split_zhou_UCF101.json

ImageNet-Sketch

The directory structure should look like

imagenet-sketch/
|–– images/ # contains 1,000 folders whose names have the format of n*
|–– classnames.txt

ImageNet-V2

The directory structure should look like

imagenetv2-matched-frequency-format-val/
