Format of json file getting from"generate_cityscapes_instance.py" wrong

[Fenanxhyy]

I've downloaded Bing and Vaihingen dataset by links provided in the readme file, then i found the code for transforming datas seems wrong, because json files of cityscapes dataset didn't match the format defined by generate_cityscapes_instance.py, eg there isn't attribution named bbox、component as so on.. Anyone provide the processed data if you've succeed testing this project. Sincere thank given for any useful help.
