opencv Python face recognizer.load

Question

I have a problem with face detection.

code:

import cv2
import os
import numpy as np
from PIL import Image 

path = 'dataSet'
cascadePath = "Classifiers/face.xml"

faceCascade = cv2.CascadeClassifier(cascadePath);
cam = cv2.VideoCapture(0)
recognizer = cv2.face.LBPHFaceRecognizer_create()
recognizer.load('trainer/trainer.yml')

AttributeError:

'cv2.face_LBPHFaceRecognizer' object has no attribute 'Load'

Help me, I already researched and still have not found an answer.

I am using python 3.6.1 and opencv 3.0

Im pretty sure if you are using OpenCV3 that it has been deprecated, I don't know what the solution is though — GPPK

@cwallenpoole not opencv3, LBPHFaceRecognizer class. I think it's been replaced and can only be used in Opencv2. Sorry if that wasn't clear — GPPK

That's because it doesn't have that property. You mean read.

recognizer = cv2.face.LBPHFaceRecognizer_create()
recognizer.read('trainer/trainer.yml')

Here's the help:

 |  read(...)
 |      read(filename) -> None
 |      .   @brief Loads a FaceRecognizer and its model state.
 |      .
 |      .   Loads a persisted model and state from a given XML or YAML file . Every FaceRecognizer has to
 |      .   overwrite FaceRecognizer::load(FileStorage& fs) to enable loading the model state.
 |      .   FaceRecognizer::load(FileStorage& fs) in turn gets called by
 |      .   FaceRecognizer::load(const String& filename), to ease saving a model.
