How to export detectron2 output as coco format to train another model

[ahmedelbehery99]

Hi, I trained a detectron2 model on a custom dataset that consists of only 250 images, and used the model to inference about 1400 images, picked around 800 good images of them, and want to use these images to train another detectron2 model.
My question is: how to export the segmented images as coco format so I can train another model with a much bigger dataset?
