Yolov5: Why postprocess of yolov5 is not same with yolov3

[yangfei963158659]

I find yolov5's postprocess is not same with yolov3。
postprocess of yolov5 is follow：
y = x[i].sigmoid()
y[..., 0:2] = (y[..., 0:2] * 2. - 0.5 + self.grid[i].to(x[i].device)) * self.stride[i] # xy
y[..., 2:4] = (y[..., 2:4] * 2) ** 2 * self.anchor_grid[i] # wh

when I deploy yolov5 in Hi3559，I find the result is incorrect。

@yangfei963158659 why would you expect them to be the same?
