COCO category id has to start wiht 0 but should start with 1.

When I train with my custom data, it only works when I start my category ids in the coco format with 0. However, the official coco format says that it should start with 1. The model trains well when I set it to 0. Do I miss something here?

Same here. Only trained after I make classes 0-indexed

Does it work when you changed the coco category ids with 0? How's the weight you trained?

Worked just fine.
