作者您好，有一个疑惑点希望您能帮忙解答。
按照我的理解，get_target返回的noobj_mask是根据未调整时候的先验框与真实框的iou将最大的先验框的noobj_mask置为0，即存在物体。而get_ignore则又将get_target返回的noobj_mask根据调整后的先验框又做了一遍这个工作。这样一来的话，get_target中的这个操作是不是就没有什么意义了？

get_ignore还计算了别的框呀

感谢您的回答，您说的对，get_ignore还计算了别的框，
所以我问的是get_target里面的noobj_mask[b, k, j, i] = 0是不是多余了，在get_target里将未调整的先验框与真实框的iou将最大的先验框的noobj_mask置为0。假设被选中的这个序号为2，那么这个框是不是在get_ignore方法里同样也会被再次选中一次？
感谢您的解惑

会再次选中，但是第二次不一定会选中
