代码说明：

说明：  One-Stage算法不需要Region Proposals阶段，可以直接产生物体的类别概率和位置坐标值，经过单次检测即可直接得到最终的检测结果。(The one stage algorithm does not need the region proposals stage, and can directly generate the category probability and position coordinate value of the object. After a single detection, the final detection result can be obtained directly.)
