custom dataset implementation

[Dharneeshkar]

Hi, Thank you so much for this awesome repo. I am currently trying a custom dataset implementation using qpic. The dataset's annotation file is in coco format. The convert_vcoco_annotations.py script converts vcoco to HOIA format. But I am trying to convert a coco format annotation to HOIA by manually adding the interactions. In this process, I am unable to understand a few things, in HOIA format : what does {subject_id , category_id, object_id} mean in "hoi_annotations" dict key, what does {category_id} mean in "annotations" dict key"
