Steps to Reproduce

prepared for COCO2017 Panoptic Segmentation Valid Dataset

http://images.cocodataset.org/zips/val2017.zip

http://images.cocodataset.org/annotations/panoptic_annotations_trainval2017.zip

1. datum convert -i /COCO2017/ -o ./OUTPUT -f datumaro # val2017.json
2. copy ./OUTPUT/annotations/val2017.json /COCO2017/annotations/
3. mv /COCO2017/annotations/panoptic2017* ./OUTPUT/
4. zip -r dataset.zip /COCO2017 # tried many times!
5. create project COCO_PANOPTIC and import dataset.zip with datumaro dataset format
6. error "No media data found"

   #  cvat/cvat/apps/engine/task.py : line 271
   if unique_entries == 0 and multiple_entries == 0:
       raise ValueError('No media data found')

Expected Behavior

I haven't seen any opensource annotation tools that support panoptic segmentation, so I'm not sure how it would work.

Possible Solution

Using a commercial annotation tool is probably the best way to go.

Context

I want to use a panoptic segmentation dataset in an open source annotation tool. I saw the documentation that CVAT can import the Datumaro format, so I thought it was worth a try.

Environment

No response

Hi, here is an example of the supported file layout: https://github.com/cvat-ai/datumaro/tree/develop/tests/assets/coco_dataset/coco_panoptic. Format documentation is here.

@zhiltsov-max Hi, I checked with COCO 2017 instance segmentation valid dataset, but I get a different kind of error. I tried changing the input format to Datumaro detect result and the output format to Datumaro, CVAT, etc. The location of the error is slightly different, but it is not imported normally.
