Using megadetector output in fastai

Hi everyone,

I am using megadetector (GitHub - microsoft/CameraTraps: Tools for training and running detectors and classifiers for wildlife images collected from motion-triggered cameras.) for detection objects. It produces bounding boxes for objects that I want to identify in a .json file. However, the format of the .json file seems to be different than from the one given in the fastai tutorials. Also, it is impossible to find any help about how to use megadetector outputs with fastai.

Does anyone here have already used megadetector with fastai? Is there a tutorial somewhere?

Thank you for your help
