※important※ Mistake in iou() of util.py

[YsYusaito]

I added exception handling.

def iou(box1, box2):
    xi1 = max(box1[0][0], box2[0][0])
    yi1 = max(box1[0][1], box2[0][1])
    xi2 = min(box1[1][0], box2[1][0])
    yi2 = min(box1[1][1], box2[1][1])
    
    if(((xi2 - xi1) < 0) or ((yi2 - yi1) < 0)):
        IoU = 0
        return IoU
    else:
        inter_area = (xi2 - xi1)*(yi2 - yi1)
        
        # Formula: Union(A,B) = A + B - Inter(A,B)
        box1_area = (box1[1][1] - box1[0][1])*(box1[1][0]- box1[0][0])
        box2_area = (box2[1][1] - box2[0][1])*(box2[1][0]- box2[0][0])
        union_area = (box1_area + box2_area) - inter_area
        # compute the IoU
        IoU = inter_area / union_area
    
        return IoU

@YsYusaito Hi. Did you get yolov3 running using inference script? I could not get any object detection suing the inference script. Please let me know if you got it running. Thanks in advance. :)

@AkkiSony Hi, I executed yolov3 object detection using inference script. For reference, I wrote my inference environment in issue #23.

@YsYusaito Thank you very much for sharing your environment issue. Did you make any changes in the inference.py and utils.py script for getting the objects detected. Please let me know if so. Would it be possible for you to share your utils.py and inference.py script? It would really help me to get yolov3 run on coral TPU. :) Thanks in advance! :)
