module 'cv2.cv2' has no attribute 'face'

serome111 commented 5 years ago

OpenCV => : opencv-python==4.0.0.21
Operating System / Platform => :Mack
Compiler => jupyter notebook

Detailed description

when I execute it tells me module 'cv2.cv2' has no attribute 'face'

Steps to reproduce

the error occurs when I use the following line reconocimiento = cv2.face.createLBPHFaceRecognizer()

I've tried installing

pip3 install opencv-contrib-python

i put pip3 freeze

appnope==0.1.0 backcall==0.1.0 decorator==4.3.0 ipykernel==4.8.2 ipython==6.5.0 ipython-genutils==0.2.0 jedi==0.12.1 jupyter-client==5.2.3 jupyter-core==4.4.0 nltk==3.4 numpy==1.15.4 opencv-contrib-python==4.0.0.21 opencv-python==4.0.0.21 pandas==0.23.4 parso==0.3.1 pexpect==4.6.0 pickleshare==0.7.4 Pillow==5.4.1 prompt-toolkit==1.0.15 ptyprocess==0.6.0 Pygments==2.2.0 python-dateutil==2.7.3 pytz==2018.7 pyzmq==17.1.0 simplegeneric==0.8.1 singledispatch==3.4.0.3 six==1.11.0 tornado==5.1 traitlets==4.3.2 virtualenv==16.0.0 wcwidth==0.1.7

I've read some solutions and I've already tried

reconocimiento = cv2.face.LBPHFaceRecognizer_create() .
reconocimiento = cv2.face.createLBPHFaceRecognizer() reconocimiento = cv2.face.createLBPHFaceRecognizer()

but it doesn't work. He tells me he hasn't found the attribute 'face' yet.

how to add the 'face' attribute?

Hey have you found the solution cause I ve same as you

serome111 commented 5 years ago

No, I don't have the solution yet, but if you find it, please share it with me.

santoshkrishnanr commented 5 years ago

even i have the same problem. but try uninstalling it by

pip uninstall opencv_contrib_python and install again pip install opencv_contrib_python

serome111 commented 5 years ago

Incluso tengo el mismo problema. pero intenta desinstalarlo por

pip desinstala opencv_contrib_python e instala de nuevo pip instala opencv_contrib_python

I tried, but the mistake persists.

santoshkrishnanr commented 5 years ago

recognizer=cv2.face.EigenFaceRecognizer_create() try this

santoshkrishnanr commented 5 years ago

print(help(cv2.face))

hritik5102 commented 4 years ago

those who got an error like this :

recognizer = cv2.face.LBPHFaceRecognizer_create() AttributeError: module 'cv2.cv2' has no attribute 'face'

Solution :

1) print(dir (cv2.face)) //on python shell 2) recognizer = cv2.face.LBPHFaceRecognizer_create()

nope that dosnt work

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();

puthusseri commented 4 years ago

print(dir (cv2.face))

Find the exact name of the function from the directory and choose that

savindu4161 commented 4 years ago

problem comes with the new versions of opencv. need a solution for that....

ibharatsaini commented 4 years ago

first uninstall opencv-python -pip uninstall opencv-python then install opencv-contrib-python -pip install opencv-contrib-python

pb1981 commented 4 years ago

I have faced same problem 'cv2.cv2' has no attribute 'face'

Only installing below didn't solve the problem for me. $pip install opencv-contrib-python

but when upgraded it solved the problem for me. $pip install opencv-contrib-python --upgrade

anyone with error even intalating opencv-contrib-python use VScode, was using pycharm when I switched to vscode worked.

alalek commented 4 years ago

Use dumping of cv.__file__ and sys.path for investigation of configuration problems (misconfigured build environments can't be fixed from OpenCV side).

VSCode

I followed your steps it worked for me but I wanted to use PyCharm IDE only so I found the solution for this to work on PyCharm IDE. Install the package opencv-contrib-python in the same way as we install opencv package on Pycharm IDE. Go to Settings, click on the plus sign. Available packages dialog box will open and type opencv-contrib-python and click on install package.

snehitvaddi commented 4 years ago

python -m pip install --user opencv-contrib-python After doing this, if you are using OpenCV == 4.* then Restart your system then use cv2.face.LBPHFaceRecognizer_create()

90% of the time this method should solve the problem.

karthi-OSCP commented 4 years ago

hey guys found the solution pip install opencv-contrib-python==3.4.7.28 try like this we have to specifically say the version try lesser version mine was 4.x so I did and no error popped up

opencv_contrib-python is the C++ binding of opencv and opencv_contrib libs opencv-python is the C++ binding of opencv lib

You must not install opencv-python if you want to use opencv_contrib-python

Read doc https://pypi.org/project/opencv-contrib-python/ :

Installation and Usage

If you have previous/other manually installed (= not installed via pip) version of OpenCV installed (e.g. cv2 module in the root of Python's site-packages), remove it before installation to avoid conflicts.

k-acme commented 4 years ago

"python3 -m pip install opencv-contrib-python" installs the latest version of OpenCV on the pi which isn't compatible with Raspberry pi 3b
- if you try installing OpenCV with any other command missing the "contrib" phrase, it will not include some important libraries, eg: Face.

For raspberry pi 3B try this:

try installing an older version by running this script on cmd line "sudo pip3 install opencv-contrib-python==3.4.6.27"

sarojkumar007 commented 4 years ago

recognizer=cv2.face.EigenFaceRecognizer_create() try this

The problem is cv2.cv2 has no attribute face, using EigenFaceRecognizer_create() does not provide a solution.

Thank you this solved my problem!

Ok so in case anyone run into the same problem:

I was using opencv 4.2 version on Mac, and it gives me

qt.qpa.plugin: Could not load the Qt platform plugin "cocoa" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: cocoa, minimal, offscreen.

Installing back to version 4.1 solves this "platform" problem but it gives out the 'cv2.cv2' has no attribute 'face' as described in the issue. And simply pip installopencv-contrib-python does not sovle this problem. Have to use pip install --force-reinstall opencv-contrib-python==4.1.2.30 to solve it.

Thanks once again!

PyCharm

VSCode

Your are using system library there. That means you have perfect version of opencv in your system library. If the code has to run in pycharm then do the following steps: go to file | settings | project interpreter | then remove opencv-python (if installed already) | while installing opencv-python check the "specify version" box then install the lower version.. This should work because there is a bug in the current version of opencv...

peetio commented 4 years ago

You can solve this problem by deleting everything on your computer related to OPENCV,. If you are using pycharm go to settings -> Project Interpreter and delete all the opencv related packages. Then to pip install opencv-contrib-python.

This worked for me after 2 days of searching the web.

The opencv-contrib consists of contrib modules and face is one of them, but it will not work if you already have the main modules of opencv installed.
