I have cv2 version 3.3.0 installed, as verified by printing cv2.__ version __
It is my understanding that version 3.3.0 should have the face module by default, as per this official documentation: http://docs.opencv.org/3.3.0/db/d7c/group__face.html
I installed opencv-python via pip.
Any ideas what is going wrong and how I can fix it?
the face module (like text,tracking and others) are in a seperate opencv_contrib repository, your installation does not have any of it.
you could retry with https://pypi.python.org/pypi/opencv-c...
(but installing via PIP has known downsides, like no gui or video file support)
maybe you want/need to install from src: https://github.com/opencv/opencv_contrib
OpenCV in homebrew is built with contrib modules by default, according to this.
However, I just tried reinstalling opencv and got this message:
Python modules have been installed and Homebrew's site-packages is not
in your Python sys.path, so you will not be able to import the modules
this formula installed. If you plan to develop with these modules,
please run:
mkdir -p /Users/cjoseph/.local/lib/python2.7/site-packages
echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/cjoseph/.local/lib/python2.7/site-packages/homebrew.pth
I ran it and that solved my problem.
