size question

there is a problem that if 
 if(minX==maxX or minY==maxY): these data is illegal for DL dataset
 so the following code is needed
 if(minX==maxX or minY==maxY):
	            print("minx/miny:%s/%s maxx/maxy:%s/%s"%(minX,minY,maxX,maxY))
	            return
            print("hhhhh======hhhhh")
