请问一下这是什么报错？谢谢。

Hi @mmcgg 从问题上看可能是detector.py里的return np.concatenate(cls_prob_list, axis=0), np.concatenate(bbox_pred_list, axis=0), np.concatenate(landmark_pred_list, axis=0)过程中某一tensor为空，具体还需您自己排查一下，我还没遇到这种情况。

好的，谢谢啦！

@mmcgg Hi 排查出来了吗？我遇到了同样的问题，也在排查中。

Zepyhrus commented 5 years ago

@mmcgg Hi，问题已解决，是部分图片会因为P网络检查不出来box，所以导致np.concatenate里的bbox_pred_list为空，典型图片是swimming的第一张，通过在MtcnnDetector.detect_face方法里加入异常处理可以解决。

Hi, @Zepyhrus，在MtcnnDetector.detect_face方法里加入异常处理具体在哪行进行条件语句的修改，新手求问望解答。谢谢

Zepyhrus commented 4 years ago

@ss24cs 异常处理跳过那几张异常图片就好了

try:
   # ... your code ... 
except:
  pass

在MtcnnDetector.detect_face方法里加入异常处理具体在哪行进行条件语句的修改？？？？？能k看哈代码吗？
