Coco import missing "extra" info in annotations

[drapado]

While exporting to COCO the "extra" entry of each annotation is built (

darwin-py/darwin/exporter/formats/coco.py

Line 308 in f29c58a

def build_extra(annotation: dt.Annotation) -> Dict[str, Any]:

). It contains "instance_id" for instance where the objects have a tracking ID.

However, the COCO importer completely ignores this "extra" category in the annotations.

Changing the importer coco.py at line 138 like this:

    if len(segmentation) == 0 and len(annotation["bbox"]) == 4:
        x, y, w, h = map(int, annotation["bbox"])
        track_id = int(annotation["extra"]["instance_id"])
        # print(dt.make_instance_id(track_id), track_id)
        return dt.make_bounding_box(category["name"], x, y, w, h, subs=[dt.make_instance_id(track_id)])

doesn't solve the issue, any ideas why?

I made it work, just created a PR: #729
