dataset.py bbox_xywh = np.concatenate([(bbox_coor[2:] + bbox_coor[:2]) * 0.5, bbox_coor[2:] - bbox_coor[:2]], axis=-1) bbox_xywh_scaled = 1.0 * bbox_xywh[np.newaxis, :] / self.strides[:, np.newaxis]

        iou = []
        exist_positive = False
        for i in range(3):
            anchors_xywh = np.zeros((self.anchor_per_scale, 4))
            anchors_xywh[:, 0:2] = np.floor(bbox_xywh_scaled[i, 0:2]).astype(np.int32) + 0.5
            anchors_xywh[:, 2:4] = self.anchors[i]

            iou_scale = self.bbox_iou(bbox_xywh_scaled[i][np.newaxis, :], anchors_xywh)

这一块 bbox_xywh_scaled的宽高是被除了 stride 的， anchors_xywh 需要同时除以 stride.
