模块“cv2.cv2”没有属性“face”

Question

在以下代码中，我在以下步骤中遇到错误：

model = cv2.face.LBPHFaceRecognizer_create()

[

错误：

^{pr2}$

Answer 1

face模块实际上并不是opencv库的一部分。相反，opencv-contrib库的^{} is part。从the readme：

This repository [opencv-contrib] is intended for development of so-called "extra" modules, contributed functionality. New modules quite often do not have stable API, and they are not well-tested. Thus, they shouldn't be released as a part of official OpenCV distribution, since the library maintains binary compatibility, and tries to provide decent performance and stability.

opencv-contrib需要单独安装。正如@james指出的（在一个已经被删除的评论中），当前获取Python版本的简单方法是：

pip install opencv-contrib-python

运行上述pip调用后，代码应该可以工作了。在
