我试图学习人脸检测,我从GeeksforGeeks教程得到了这个代码。然而,当我运行这两个文件中的一个时,它显示错误AttributeError:模块“cv 2”没有属性“LBPHFaceRecognizer_create”。我尝试卸载open cv,安装pip install opencv-contrib-python,以及重新安装open cv并运行它。我目前运行的是open cv 2 4.5.5。教程建议从cv2.face.LBPHFaceRecognizer_create()
中删除'.face'以运行cv 2,但是当我使用.face运行它时,它显示模块'cv 2'没有属性'face'。拜托,谁来帮帮我

我认为你可能需要明确地声明“cv2.face”而不仅仅是“face...”
在这样做之前...你是否确认你安装了包含Face模块的OpenCV版本?你可以这样检查:
如果没有,就像这样安装:
