Things and stuff id confusion

[nazib]

Hi @VSainteuf,
I was trying to train detectron panoptic segmentation model using PASTIS dataset. We are basically doing an eavluation of five different panoptic segmentation models for multispectrum sattelite data. We choose PASTIS as our primary data since its clean and well curated, (Thanks for clean data buildup). Most of themodels we choose can easily be trained using coco format. We decided to make a coco formated jeson file for PASTIS so that we can easily train those models on PASTIS. But here is a thing which confuses use while creating jeson in coco panoptic format. COCO format requires 'stuff" id and 'things' id in its format. When I check your paper and code we can easily relate the nomenclature you provided as stuff id or category_id but how should we define the instance id. I checked the code in your data loader and seems like 'zone' files are acting as instance id. Can you pls clarify how to map 19 class category_id to things id or 'id' in coco format.?

kind regards
