pool.starmap(filter_pred, [(config, pred) for pred in predictions])ZeroDivisionError: float division by zero

Hi
I trained your PIXOR network for 40 epoch with decrease in loss curves.

How when i execute python main.py --mode=val --name=default , the below error occurs.. Kindly help please

Traceback (most recent call last):
File "/usr/lib/python3.5/multiprocessing/pool.py", line 119, in worker
result = (True, func(*args, **kwds))
File "/usr/lib/python3.5/multiprocessing/pool.py", line 47, in starmapstar
return list(itertools.starmap(args[0], args[1]))

iou = [box.intersection(b).area / box.union(b).area for b in boxes]

ZeroDivisionError: float division by zero

Did you fix it? Got the same problem.

@HenryJunW @chowkamlee81 did you find the reason? I also meet this problem. According to the definition of IOU, I think that the divisor cannot be 0

I can't understand why intersection.area/union.area have this problem too.Did you fix it?
