每个方块生产6个anchor用来做初始预测方框,9个方块就生产54个anchor,其他特征层同理,最后把所有特征层生产的anchor通过np.concatenate(anchors, axis=0)函数拼接在一起得到anchor为(8732,4)即ssd输出特征层固定输出8732个,注意这里生成的anchor与要预测的图片无关,不管输入什么图片都固定输出这些anchor,其坐标的格式是...

2.Concatenate StartKey and EndKey according to the composition of the RowKey This means to concatenate queries StartKey and EndKey based on which fields the RowKey consists of, and the predicates of the current query. For example, when RowKey is composed as follows: ...
