[Detector Support]: labelmap for Frigate+ yolonas model

[zoechi]

Describe the problem you are having

I just generated my first model. I used yolonas with OpenVINO.
The docs https://docs.frigate.video/configuration/object_detectors/#yolo-nas say with such a model the label_map should be labelmap_path: /labelmap/coco-80.txt
I don't know what a labelmap is or does and also not where I should get that coco-80.txt file from.
I installed Frigate using NixOS which includes coco_91cl_bkgr.txt and labelmap.txt.

What is the purpose of the labelmap and how should this be resolved?

Currently I have coco_91cl_bkgr.txt configured and I don't get an error.
Are there any disadvantages of using not the labelmap as suggested in the docs?

this is wrong, the docs are saying the labelmap should be that when running that yolonas model specifically. You should not be configuring the labelmap when you use frigate+ as everything is configured for you in that case

Great, thanks
