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

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 this it worked for me

pip install --force-reinstall opencv-contrib-python==4.1.2.30

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

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..

recognizer = cv2.face_LBPHFaceRecognizer.create()

open cmd , then --> pip install opencv-contrib-python

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.

Installing opencv-contrib-python solved the issue. I had installed only opencv-python, After Installing opencv-contrib-python, solved the issue.

pip install opencv-contrib-python

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()

write

pip install opencv-contrib-python --upgrade

if gives error then write

pip install opencv-contrib-python --user

it will work fine for 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"

I am also facing an same issue after installation of these below command in my command prompt.

> pip install opencv-contrib-python
> pip install opencv-contrib-python --user

Facing this below error in jupyter notebook.

After i am tried with visual studio code but make sure your running with this below confirmation commands in your command prompt or terminal.

I will suggest you to try in command prompt.
