How to run yolov5 for inference?

I want to use yolov5 for object detection as inference not training, I downloaded the model from "https://ift.tt/2TVnKIg" I ran detect.py and I got the following error:

RuntimeError: shape '[1, 3, 85, 80, 80]' is invalid for input of size 819200

Please would you mind helping me out for dealing with this issue, any note or suggestion
