Did you try the opencv3 branch?

in OpenCV3, please use cv2.ml.KNearest_create() instead.

@Django-27 Isn't that already done in the branch? classification.py:46

Might not be the case at that time (2016) but now with a opencv 4 version, I got the issue cause condition is ==3

class KNNClassifier(Classifier):
    def __init__(self, k=1, debug=False):
        if get_opencv_version() == 3:
            self.knn = cv2.ml.KNearest_create()
        else:
            self.knn = cv2.KNearest()
        self.k = k
        self.debug = debug
