ImportError in prep_mtsd_for_yolo.py

[JohnZhang000]

Thank you very much for your solid contribution, which provides a unified benchmark for evaluating physical adversarial examples. We are trying to follow your work but encountered an error when preparing the dataset.

when we run prep_mtsd_for_yolo.py, the following error happens:
ImportError: cannot import name 'MIN_OBJ_AREA' from 'hparams'
similar import error happens to PATH_APB_ANNO, PATH_MTSD_BASE,PATH_MTSD_BASE

By the way. failed to find prep_mtsd_for_detectron.py described in README.md

Thank you for taking an interest in our work! And sorry for the trouble and the delay. prep_mtsd_for_yolo.py is deprecated; we previously used it with the old YOLO code/scripts.

I believe that it is not necessary to preprocess MTSD now, but I couldn't exactly test this because I haven't been able to download the original MTSD from their website https://www.mapillary.com/dataset/trafficsign. I will keep you posted if I get any updates on this.
