can't find module cv2

[ndiayefrancisco2000]

Hello,
I followed your installation instructions for OpenCV on adafruit for this project and installed everything successfully. My purpose is to test the facial recognition feature with LEDs; basically my picture is taken with the help of a push button and compared with the positive/negative training data, and if my picture is recognized the green LED turns on, if not, the red LED turns on. I used your capture-positives.py for the training and everything worked fine, but I had to edit your config.py and box.py since i'm not using a box or servos.
My problem is: in the capture-positives.py file 'import cv2' works fine, but when i use it in my python script to include the push button and picamera and OpenCV it tells me it can't find module cv2. I have no idea why it can't find the file this time and i'm stuck. Any help from you will be appreciated.
