AttributeError: 'module' object has no attribute 'face'

[sungjinp11]

I got an error when running opencv in Python on raspberry pi.

I tried to find and apply it to fix the error, but it did not work out. I also confirmed that the module "face" is in the file opencv_contrib-3.3.0. I do not know why for some reason.

error 1

Traceback (most recent call last): File "training.py", line 13, in recognizer = cv2.face.createLBPHFaceRecognizer() AttributeError: 'module' object has no attribute 'face'

error 2

Traceback (most recent call last): File "training.py", line 13, in help(cv2.face) AttributeError: 'module' object has no attribute 'face'

i tried "help(cv2,face)" and tried "help(cv2.face.createLBPHFaceRecognizer)"

[alalek]

Usage questions should go to Users OpenCV Q/A forum: http://answers.opencv.org This tracker is for issues and bugs that needs fix in OpenCV.

Issue is created for wrong repository (should be "opencv_contrib", but no need to post the same "questions" there).

This function was renamed (there is not strong requirements for API stability in opencv_contrib). Documentation is here with Python signatures.

[chinyavadav]

update your opencv by "python -m pip install opencv-contrib-python"

[sidd5sci]

i have tried it but this doesn't work too. still giving the same error

recoginizer = cv2.createLBPHFaceRecognizer() AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer'

recoginizer = cv2.face.createLBPHFaceRecognizer() AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer'

[chinyavadav]

recoginizer = cv2.createLBPHFaceRecognizer() AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer'

if you have that error it means the face class is installed. but the updated version of opencv-contrib doesnt have 'createLBPHFaceRecognizer' it changed the name. so to find out print(help(cv2.face))

[mayank8995]

Thank you very much chinyavadav.Your solution is the only solution which is fixing this problem.

[sachinAcchi]

i am getting error recoginizer = cv2.face.createLBPHFaceRecognizer() AttributeError: 'module' object has no attribute 'face'

[alaa-aqeel]

maybe change its name in the new version of cv2

• Make sure that the "face" is inside the cv2 using print(dir (cv2)) or help(cv2) # attribute cv2

[chinyavadav]

what version of python are you using

[radwa4]

i have same error this is my version of python 3.6.5

[alalek]

@radwa4 Why are you posting text messages via screenshots? At least this is completely useless to search related information. Don't do this again.

Error: No space left on devices

Perhaps your last package installations have been failed and your system goes into broken state.

I don't see any message related to OpenCV, so your comment is considered unrelated to this issue and will be removed tomorrow.

[hope-miky]

this works for me............ cv2.face.LBPHFaceRecognizer_create()

[sleman-khadoor]

Tesfamichael1074 please give me the tutorial u followed

[IamDixit]

I had similar issue. I solved it by updating cv2 library python -m pip install opencv-contrib-python

[sleman-khadoor]

i am using opencv 3.4 on raspberry pi 3 and i am facing the same problem when i did what u say " python -m pip install opencv-contrib-python " i had error message that cv2 doesnt exist is there any thing i should do after updating the library?

when i tried updating using python -m pip install opencv-contrib-python it showed error of permission denied. any idea of how to solve it Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: 'C:\Users\Alok Awasthi\AppData\Local\Programs\Python\Python36-32\Lib\site-packages\cv2\cv2.cp36-win32.pyd' Consider using the --user option or check the permissions.

[IamDixit]

Hi Alok, Try to add sudo before your cmd if u are not using Windows os.

[miladdiba]

Hi, I did updated cv2 using above mentioned command "sudo pip install opencv-contrib-python"

Now, when i import cv2 , error occurs that no such file exists

Anybody plz help asap. So grateful about your concerns.

[santosh2702]

Alok use command it will work.

pip install opencv-contrib-python --user

i am getting error recoginizer = cv2.face.createLBPHFaceRecognizer() AttributeError: 'module' object has no attribute 'face' first pip install opencv-contrib-python and try like this

and for training data (if get any error for recoginizer.load(....yml)) use recoginizer.read(....yml)

[serome111]

I've got the same mistake and I put help(cv2.face) module 'cv2.cv2' has no attribute 'face'

How do I add the face module? to cv2

[Earbaj]

open cmd and run as administrator and upgrade using this command python -m pip install opencv-contrib-python

python -m pip install opencv-contrib-python

ya tengo el opencv-contrib-python en su última version.

Bro, please tell me how to solve that issue

[jeweldhali]

use this line recognizer=cv2.face.LBPHFaceRecognizer_create();

[rohitkasan]

recognizer = cv2.createLBPHFaceRecognizer() try this out

[abhyamgupta123]

first of all upgrade your opencv pakage by using command ' python -m pip install opencv-contrib-python --upgrade' , and then try out using 'recognizer=cv2.face.LBPHFaceRecognizer_create()' hope this helps

[hritik5102]

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()

those who got an error like this :

Try using cv2.face.createLBPHFaceRecognizer() because the repositories of updated for more information try using the command print(help(cv2.face)) in the programm

update your opencv by "python -m pip install opencv-contrib-python"

牛逼！确实好用！ Niubi! That's really work!

[devendrakanade]

i also have also this error but it is solved by this cmd pip install opencv-contrib-python or use pip install opencv-contrib-python --user

[aashutosh0012]

Installing opencv-contrib-python solved the issue. I had installed only opencv-python, After Installing opencv-contrib-python, solved the issue.

pip install opencv-contrib-python

[harshtitoria]

If uou are using python3 use pip3 instead of using pip for: pip3 install opencv-contrib-python.

then you can simply do: recognizer = cv2.face.LBPHFaceRecognizer_create()

no its a help command try it in python

print(help(cv2.face))

its will give you the python contrib and how u have to type it for me its recognizer = cv2.face.createLBPHFaceRecognizer()

[TumeloMosepele]

recoginizer = cv2.createLBPHFaceRecognizer() AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer'

if you have that error it means the face class is installed. but the updated version of opencv-contrib doesnt have 'createLBPHFaceRecognizer' it changed the name. so to find out print(help(cv2.face))

how do i get to do that?

[vamsi1609]

Yeah for me it was the same cv2.face.createLBPHfaceRecognizer() and it worked for me around i guess 6 months ago after that i didn't use it much. So now i am not sure whether it's the same command or not.
