AttributeError: 'module' object has no attribute 'face' OS X
I'm trying to build opencv with opencv_contrib on OS X. I will explain step-by-step what I did:
- I downloaded the OpenCV 3.1 from: http://opencv.org/downloads.html
- I also downloaded the opencv_contribfrom: https://github.com/Itseez/opencv_contrib
- I put the opencv_contrib folder inside the opencv-3.1.0 folder
- I created a folder called "build" inside the opencv-3.1.0 folder
- From the terminal I went to the build folder:
/Users/kelvinsp/Downloads/opencv-3.1.0/build/ Then I ran the following commands:
cmake -DOPENCV_EXTRA_MODULES_PATH=/Users/kelvinsp/Downloads/opencv-3.1.0/opencv_contrib/modules /Users/kelvinsp/Downloads/opencv-3.1.0/make -j5sudo make installThen, in the python terminal I tried to run the command:
import cv2and receive the following error:ImportError: No module named cv2- Searching in stackoverflow, I found a solution and I ran the command:
export PYTHONPATH=/usr/local/lib/python2.7/site-packages/:$PYTHONPATH - Now the import cv2 command is working, but when I ran the command
help(cv2.face)I got the following error:AttributeError: 'module' object has no attribute 'face'
Can someone help me please? I don't know what I'm doing wrong.

can you show us the cmake output ? (append it to your question)
3.:I put the opencv_contrib folder inside the opencv-3.1.0 folder
rather put it next to your opencv-3.1.0 folder
Thanks @berak.
I rebuild the opencv with the opencv_contrib folder next to the opencv folder (not inside), but still not working.
I updated the question with the cmake output link.
Yesterday I also tried to use the following cmake command to build:
but it didn't work.
"but it didn't work." -- please never say that again.
Sorry for ask that, but why never say "but it didn't work."? My english is not so good, but in portuguese it's normal to say that. In my mind, it means that I built everything with this command but I got the same error message.
help(cv2.fuzzy) help(cv2.plot) help(cv2.text)and got the same error:AttributeError: 'module' object has no attribute '...'apologies, never meant to offend you in any way, - usually, it sounds more like whining, but please let's drop the whole thing.
ando, not a dropbox or any external thing, please really just edit your question again, and append the cmake output there. very likely we'll find some explanation in there !
also, did you have a previous cv2.pyd installed ?
cv2.__version__would tell, if you're using the right one.No problem, you don't offended me, I just wanted to understand to not do it again, but ok I understood your point.
I put the entire cmake output in the question.
I ran the command
c2.__version__and I got this output'3.0.0'. Apparently I have an older version in somewhere.
