python opencv人脸识别器

Question

嗨，我正在尝试做一个人脸识别器。 我每个人都有一些目录，有图片。 我的代码有问题：

recognizer = cv2.face_LBPHFaceRecognizer
path = curFolder+"/usersPics/"
path1, dirs, files = next(os.walk(path))
for i in dirs:
    path2, dirs2, files2 = next(os.walk(path+"/"+str(i)))
    for j in files2:
        print(j)
        pil_image = Image.open(path+"/"+str(i)+"/"+str(j))
        image_array = np.array((pil_image),"uint8")
        recognizer.update(image_array,np.array(i))

当我运行它时，我会得到这个错误：

descriptor 'train' requires a 'cv2.face_FaceRecognizer' object but received a 'numpy.ndarray'
