attributeerror: module 'cv2.face' has no a

Question

So i'm doing a little personal project but i keep getting this error when I try to create the recognizer. i have opencv-contrib and everything. Does anyone know whats going on? code posted below

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

cascadePath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascadePath)

recognizer = cv2.face.createLBPHFaceRecognizer()

it gets caught on that last line. I've tried reinstalling all modules already. Not really sure what else to do. The weird thing is it works on my laptop but not my desktop. They both have the same modules, same python release and running the exact same code.

Answer 1

Try to update your opencv by "python -m pip install opencv-contrib-python" ps: you have to delete the CV2 repository from the Python rep and then run this command (in the CMD windows) if it doesn't work

Answer 2

I had this problem running opencv Version 3.4.1. Here is what I did.

SPECS: Raspberry pi 3B, OS: Raspbian, Version: 9 (Stretch), Python 3, opencv Version 3.4.1

Check opencv version in python

import cv2

cv2.__version__

1) sudo pip install opencv-contrib-python

*After this I could not import cv2 in python until I installed the following.

2) sudo apt-get update

3) sudo apt-get install libhdf5-dev

4) sudo apt-get update

5) sudo apt-get install libhdf5-serial-dev libqtgui4 libqt4-test

Answer 3

• Uninstall this package (opencv-python) by command :-
• pip uninstall opencv-python
• Install the library opencv-contrib python using command :-
• pip install opencv-contrib-python
• then add or check :-
• recognizer = cv2.face_LBPHFaceRecognizer.create()
• It will work fine
• The problem was in opencv-python library cv2.face is not present so it shows attribute missing problem, so install new lib by uninstalling previous one if installed..

Answer 4

You are using Opencv 3.x, in the new version few modules has been removed. You have two options: 1. Add opencv_contrib module to your existing opencv 3.x version. Here's the link https://github.com/opencv/opencv_contrib 2.you can use older versions of Opencv. Like opencv 2.4.x

Answer 5

There are some missing modules for contributed libraries in the default pip install opencv-python so you need pip install opencv-contrib-python

Answer 6

Try to use this:

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

# Path for face image database
path = 'dataset'
recognizer = cv2.face_LBPHFaceRecognizer.create()
detector = cv2.CascadeClassifier("haarcascade_frontalface_default.xml")
