Exploring the Error : AttributeError: module ‘cv2.cv2’ has no attribute ‘createLBPHFaceRecognizer’
This is a common error which occurs when opencv has a faulty installation or opencv dependencies are not installed.
First of all, let us check out how the message of the error looks like.
Bellow I will present multiple solutions some have worked for me and others have worked for other developers.
Solution 1 : install opencv-contrib-python
The solution is simple, start by installing opencv-contrib-python. You can do that using the command bellow.
#
sudo pip install opencv-contrib-python
#
If that did not work You can also try the following command.
#
sudo pip3 install opencv-contrib-python==4.5.0.4
#
You can choose a version here https://www.piwheels.org/project/opencv-contrib-python/#install
You can now install these libraries using the following command.
#
sudo apt install libaec0 libaom0 libatk-bridge2.0-0 libdrm2 libepoxy0 libfontconfig1 libgdk-pixbuf2.0-0 libgfortran5 libgme0 libgraphite2-3 libgsm1 libgtk-3-0 libvorbis0a libvorbisenc2 libvorbisfile3 libvpx5 libwavpack1 libxcursor1 libxdamage1 libxfixes3 libxi6 libxinerama1 libxkbcommon0 libxrandr2 libxrender1 libxvidcore4 libzvbi0 libsnappy1v5 libsoxr0 libspeex1 libssh-gcrypt-4 libswresample3 libswscale5 libsz2 libthai0 libtheora0 libtiff5 libtwolame0 libva-drm2 libva-x11-2 libva2 libvdpau1 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 libatk1.0-0 libatlas3-base libatspi2.0-0 libavcodec58 libavformat58 libavutil56 libbluray2 libcairo-gobject2 libcairo2 libchromaprint1 libcodec2-0.8.1 libcroco3 libdatrie1 libwayland-client0 libwayland-cursor0 libwayland-egl1 libwebp6 libwebpmux3 libx264-155 libx265-165 libxcb-render0 libxcb-shm0 libxcomposite1

For most people, the error should be gone by now. If it does not please follow the solution bellow.
Solution 2 : uninstall opencv-python first
The second solution is as simple as the previous solution.
First, you should start by removing opencv-python from your system.
You can do that by using the command bellow.
