AttributeError:模块"cv2"没有属性"face" [英] AttributeError: module 'cv2' has no attribute 'face'

问题描述

我尝试按照以下指南在raspberry3上安装opencv3.4.0:

I tried to install opencv3.4.0 on a raspberry3 following this guide: https://www.life2coding.com/install-opencv-3-4-0-python-3-raspberry-pi-3/

现在的问题是我不知道为什么python3会给我错误:

Now the problem is that I could not figure out why python3 gives me the error:

AttributeError: module 'cv2' has no attribute 'face'

每当我尝试执行

face_recognizer = cv2.face.LBPHFaceRecognizer_create()

我已经安装了opencv3.4.0以及其他模块:opencv3.4.0_contrib.我知道面部"必须成为额外模块的一部分.我仍然不知道是什么原因导致此错误.

I already installed opencv3.4.0 and also the additional modules: opencv3.4.0_contrib. I know that "face" needs to be part of the extra modules. Still I cannot figure out what causes this error.

有人可以帮我吗?

推荐答案

最后，我开始使用它了.我只是在两个安装中都使用了pip:

Finally, I got it working. I just used pip for both installations:

pip install opencv-python
pip install opencv-contrib-python
