When I run the predict(src) function, it returns only a int, instead of a int and a double.
using help() throws this:
Help on built-in function predict:
predict(...) method of cv2.face_BasicFaceRecognizer instance
predict(src) -> retval or predict(src) -> label, confidence or predict(src, collector[, state]) -> None
The code I'm using is:
nbr_predicted, conf = recognizer.predict(imgp)
imho, that's a bug in the generated wrapper code. the 'label only' code shadows the 'label and confidence' part in pyopencv_cv_face_face_FaceRecognizer_predict .
as a quick workaround, remove the CV_WRAP here , and rebuild. this will disable the 'label only' version, but let you acess the confidence/distance.
I have commented out CV_WRAP int predict(InputArray src) const;
But when I build I get the following error:
/home/pi/opencv_contrib-3.1.0/modules/face/src/facerec.cpp:75:5: error: prototype for ‘int cv::face::FaceRecognizer::predict(cv::InputArray) const’ does not match any in class ‘cv::face::FaceRecognizer’

Thanks
alexylem, I have the same problem. If you know how to fix it, please help.
Well just one Question. nbr_predicted, conf = recognizer.predict(imgp)
here imgp is your array????
@Craftech Systems : it is the image (array). what are you asking ?
