Dataset instructions

IAP is trained and evaluated on MTIL benchmark from ZSCL. For datasets, we follow DIKI and apply the dataset splits from CoOp.

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

$datasets/
|–– caltech-101/
|–– oxford_pets/
|–– stanford_cars/
|-- ...

The instructions to prepare each dataset are detailed below.

Caltech101

• Create a folder named caltech-101/ under $datasets.
• Download 101_ObjectCategories.tar.gz from https://data.caltech.edu/records/mzrjq-6wc02 and extract the file under $DATA/caltech-101.
• Download split_zhou_Caltech101.json from this link and put it under $datasets/caltech-101.

The directory structure should look like

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