attributeerror: module 'cv2.face' has no attribute 'createlbphfacerecognizer'

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.

How did u compile your `opencv_contrib`? – eshirima Aug 13 '17 at 00:41 — eshirima, Aug 13 '17 at 00:41

Had the same problem. Use:

recognizer = cv2.face.LBPHFaceRecognizer_create()

It worked for my program.

Under Windows 7, I was able to resolve the issue by simply uninstalling and re-installing opencv:

pip uninstall opencv-contrib-python
pip install opencv-contrib-python

The recogniser is called by:

recognizer = cv2.face.LBPHFaceRecognizer_create()

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

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

Try to use this:

from PIL import Image

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

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

I fixed this issue with two commands:

First: sudo pip3 uninstall opencv-contrib-python

Second: sudo python3 -m pip install opencv-contrib-python==3.3.0.9

This fixed my issues. Hope it helps somebody! Also, if you are using python2, replace “pip3” with “pip” and “python3” with “python”

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..

OpenCV has removed the cv2.face module from version 4.4.0 onwards. This module was used for face recognition and included algorithms such as Eigenfaces, Fisherfaces, and LBPH (Local Binary Patterns Histograms).

Instead of using the cv2.face module, OpenCV now recommends using the face_recognition library, which is a third-party library that provides a simple interface for face recognition tasks. This library uses dlib's implementation of face recognition algorithms, which is more accurate and faster than the algorithms included in the cv2.face module.

You can install the face_recognition library using pip, by running the following command in your terminal or command prompt

pip install face_recognition
import face_recognition

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

I fixed this issue by installing: sudo pip install opencv-contrib-python.

Then look for correct format.

python2 is default

Basically the problem is that python3 and python2 have different format of code.

recognizer = cv2.face.LBPHFaceRecognizer_create()

This is the format of python2.

recognizer = cv2.face.createLBPHFaceRecognizer()

This is the format of python3

Even I had this problem when I ran the code using Jupyter Notebook. If you are running it on Jupyter Notebook , then download it as pyhton(.py) file and try to run it in Anaconda Prompt or Command Prompt. This solved the problem for me. Thank You.

If you are using python3 use pip3 instead of pip: pip3 install opencv-contrib-python

Then you can simply do: recognizer = cv2.face.LBPHFaceRecognizer_create()

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

This will download a 41.5MB file and install that in your python package folder , after that you can check by simply First "import cv2" then typing "print(dir(cv2.face))" that will return a list of attributes in cv2.face which will include "createlbphfacerecognizer"

The Library can change how we access methods or the method names by time. So, keep an eye for that.

Here's the latest one: recognizer = cv.face.LBPHFaceRecogniser.create()

clf=cv2.face.LBPHFaceRecognizer_create() AttributeError: module 'cv2' has no attribute 'face'

I also got this error... This is because your opencv module is out of date.

so please uninstall opencv:

pip uninstall opencv-python

and reinstall opencv using this command:

pip install opencv-contrib-python

and replace this line to:

recognizer = cv2.face.LBPHFaceRecognizer.create()
