Traceback (most recent call last):

Process finished with exit code 1.

I am using Windows platform. python 3.6 version.Thanks in advance.

Answer 1

You need to install opencv-contrib

pip install opencv-contrib-python

It should work after that.

Answer 2

if you are using python3.x and opencv==4.1.0 then use following commands First of all

python -m pip install --user opencv-contrib-python

after that use this in the python script

cv2.face.LBPHFaceRecognizer_create() 

Answer 3

You might be running Python3 and therefore you are supposed to use pip3 to install the opencv-contrib package :

pip3 install opencv-contrib-python

This worked for me.

Answer 4

Use the following

recognizer = **cv2.face.LBPHFaceRecognizer_create()**

After you install:

pip install opencv-contrib-python

If using anaconda then in anaconda prompt:

conda install pip

then

pip install opencv-contrib-python

Answer 5

opencv has changed some functions and moved them to their opencv_contrib repo so you have to call the mentioned method with:

recognizer = cv2.face.createLBPHFaceRecognizer()

Note: You can see this issue about missing docs. Try using help function help(cv2.face.createLBPHFaceRecognizer) for more details.

Answer 6

I got openCV installed smoothly in my mac by:

$ brew install opencv
$ brew link --overwrite --dry-run opencv // to force linking
$ pip3 install opencv-contrib-python

I got it at windows 10 using:

c:\> pip3 install opencv-python
c:\> pip3 install opencv-contrib-python

Then I got it tested by

$ python3
Python 3.7.3 (default, Mar 27 2019, 09:23:15) 
[Clang 10.0.1 (clang-1001.0.46.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'4.1.0'
>>> exit()

Answer 7

python -m pip install --user opencv-contrib-python

After doing this just Restart your system and then if you are on Opencv >= 4.* use :
recognizer = cv2.face.LBPHFaceRecognizer_create()

This should solve 90% of the problem.

Answer 8

For me changing createLBPHFaceRecognizer() to

recognizer = cv2.face.LBPHFaceRecognizer_create()

fixed the problem

Answer 9

I had a similar problem:

module cv2 has no attribute "cv2.TrackerCSRT_create"

My Python version is 3.8.0 under Windows 10. The problem was the opencv version installation.

So I fixed this way (cmd prompt with administrator privileges):

1. Uninstalled opencv-python: pip uninstall opencv-python
2. Installed only opencv-contrib-python: pip install opencv-contrib-python

Anyway you can read the following guide:

Answer 10

RESTART YOUR IDE

I tried all of the different things but nothing seems to be working then I just restarted my IDE and it worked like charm.

Still, if it does not work then try restarting your system.

FYI, I am working on the following versions

opencv-contrib-python==4.4.0.46
opencv-python==4.1.2.30

Answer 11

I have some problem while executing :

import cv2 as cv
face_recognizer = cv.face.LBPHFaceRecognizer_create()

generating an error : cv2.cv2 has no face attributes.

if i try to install with :

sudo pip install opencv-contrib-python

it will take hours to compile and finally nothing works !

But on the site : https://www.piwheels.org/project/opencv-contrib-python/#install only version 4.4.0.46 has files !

Then I try this :

sudo pip3 install opencv-contrib-python==4.4.0.46

installation is instantaneous !!!

I need to install some other libraries :

sudo apt install libaec0 libaom0 libatk-bridge2.0-0 libatk1.0-0 libatlas3-base libatspi2.0-0 libavcodec58 libavformat58 libavutil56 libbluray2 libcairo-gobject2 libcairo2 libchromaprint1 libcodec2-0.8.1 libcroco3 libdatrie1 libdrm2 libepoxy0 libfontconfig1 libgdk-pixbuf2.0-0 libgfortran5 libgme0 libgraphite2-3 libgsm1 libgtk-3-0 libharfbuzz0b libhdf5-103 libilmbase23 libjbig0 libmp3lame0 libmpg123-0 libogg0 libopenexr23 libopenjp2-7 libopenmpt0 libopus0 libpango-1.0-0 libpangocairo-1.0-0 libpangoft2-1.0-0 libpixman-1-0 librsvg2-2 libshine3 libsnappy1v5 libsoxr0 libspeex1 libssh-gcrypt-4 libswresample3 libswscale5 libsz2 libthai0 libtheora0 libtiff5 libtwolame0 libva-drm2 libva-x11-2 libva2 libvdpau1 libvorbis0a libvorbisenc2 libvorbisfile3 libvpx5 libwavpack1 libwayland-client0 libwayland-cursor0 libwayland-egl1 libwebp6 libwebpmux3 libx264-155 libx265-165 libxcb-render0 libxcb-shm0 libxcomposite1 libxcursor1 libxdamage1 libxfixes3 libxi6 libxinerama1 libxkbcommon0 libxrandr2 libxrender1 libxvidcore4 libzvbi0

It works well since when using import cv2 face !!

I have now in pip3 freeze :

opencv-contrib-python==4.4.0.46
opencv-python==4.5.1.48

Hope this will be usefull !!!!!

Answer 12

For me, I had to have OpenCV (3.4.2), Py-OpenCV (3.4.2), LibOpenCV (3.4.2).

My Python was version 3.5.6 with Anaconda in Windows OS 10.

Answer 13

Check your OpenCV version

import cv2
cv2.__version__

If your are running Python v3.x and OpenCV v4 and above:

pip install opencv-contrib-python

Try running your program again. This should now work.
