Detectron2: train Panoptic Segmentation model on custom dataset

[Cyril9227]

❓ How to train Panoptic Segmentation on a custom dataset ?

Hello everyone,

My question is two-fold :

1. What is the expected Detectron2 format for Panoptic Segmentation ? In the PS paper, they are talking about a pixel-wise annotation (either stuff class or instance ID) but it seems that D2 requires bounding boxes as well.
2. Is it possible to train PS on a custom dataset with only pixel-wise annotations ?

Thanks,

Cyril

At the moment we don't have instructions to train panoptic segmentation models on custom dataset. Our code now expects panoptic segmentation data in COCO format, which is unfortunately not well-documented.
