问题描述

我正在尝试实现面部识别登录系统，但出现错误无法将操作数与形状(128，)(0，)一起广播"，并且我不知道如何解决或如何解决它.这是我已执行的view.py和facedetector.py以及从服务器获取的错误:

I am trying to implement a facial recognition login system but I have an error "Operands could not be broadcast together with shapes (128,) (0,)" and I have no idea what or how can I solve it. Here are my view.py and facedetector.py that have been implemented and the error that I get from my server:

someone has already asked this question previously Operands could not be broadcast together with shapes (128,) (0,) error but didn't get much response. probably because he didn't provided complete code.

我正在得到错误提示:

推荐答案

face_recognition.compare_faces 函数的第一个参数应为 中所述).将您的 djangoproject/mysite/pages/views.py 第33行更改为:

The first argument for face_recognition.compare_faces function should be a list as stated in the documentation. Change your djangoproject/mysite/pages/views.py line 33 to:

check=face_recognition.compare_faces([face_1_face_encoding], face_encodings)

解决异常的原因.
