Export coco instances from datumaro format doesn't load annotations

[CahSrv]

Hi guys, i have a problem.

I need to export annotations in datumaro format to coco instances in the following scenario:

First, annotations are made in cvat 2.6.2 and exported in formamo datumaro 1.0 images. (without saving the media)

Then, in Python, after some data processing, the annotations are exported to the coco instances format:

the dataset is exported, but the annotations are empty:

Temporary solution

Add media to datumaro item

Any better solution?

in short, the annotations are not converted to the new format if there is no media, but the annotations do exist.

Sorry for the late response. I'll take a look. Please wait some more days.
I would appreciate it if you could share which version of datumaro you used in python.

in python: datumaro==1.2.1

Hi, I'd like to ask something for clarification. I guess you're using Bbox annotations only, don't you?

Thank you for the reporting this issue. I modified coco exporter to deal with this issue. Coco exporter will be able to export annotations which doesn't require media(image) information when there's no media.
