OverflowError: cannot convert float infinity to integer

[albertyou2]

hi @Grad-CSE2016

when I was ruining this command 'python TrackingPeople.py' with my .mp4 file,an error occured:
/home/sojoyoo/pedestrian_Grad-CSE2016/sort.py:68: RuntimeWarning: divide by zero encountered in divide
h = x[2]/w
Traceback (most recent call last):
File "TrackingPeople.py", line 66, in
x1,y1,x2,y2,n=int(tracker[0]),int(tracker[1]),int(tracker[2]),int(tracker[3]),int(tracker[4]),;
OverflowError: cannot convert float infinity to integer

I'm using python 2.7,opencv 3.1.0.And i run 'python TrackingPeople.py' directly with out any preproccess.
Am ' i missing sth?
