module 'cv2' has no attribute 'face'

[WBTHL]

I got this error while trying to run 02_face_training.py. I think I got opencv_contrib successfully installed by following Adrian Rosebrock's Raspbian Stretch: Install OpenCV 3 + Python on your Raspberry Pi. cv2.version also returns the correct value.

Some answers from Stackoverflow suggest running these command: pip install opencv-python and pip install OpenCV-contrib-python. After doing that, however, import cv2 gets an error and version check fails as well.

So, anyone got a solution?

PS: Pillow is installed and I'm doing all of these within the 'cv' virtual environment.

@WBTHL I have met the same problem and I found the solution at StackOverflow.
You should try
pip install opencv-contrib-python
and it should work after you execute it.
As it works fine for me.

@Veeupup Thanks for your reply!

After checking the build folder for OpenCV installation, I finally find out what's wrong. All modules from opencv_contrib are not installed due to a silly typing error during the installation... And that explains why I'm missing the 'face' module. Thanks again!
