- `OCL_class_*.pkl` contains the annotation of the three splits:
  - The pickle files are stored in binary, please use `"rb"` mode.
  - Each file is a list of image annotations. Each image has multiple object instances with bounding box, attributes, affordances, object category and causal rules (attribute->affordance).
  - Most files are from COCO, ImageNet-1K, aPY and SUN-attribute. Around 5K images are from the internet, whose urls are listed in `image_urls_from_web.json`. Please use the md5 (or file name) to match the files to the annotations.
- `OCL_class_*.json` contains the list of classes.

*We will attach the download script asap.*
