COCO 2017 Panoptic Segmentation Val Dataset (Datumaro format) Import Error

[sailfish009]

Actions before raising this issue

• I searched the existing issues and did not find anything similar.
• I read/searched the docs

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.
