OpenCV python on raspberry

I've installed on my raspberry opencv python module and everything was working fine. Today I've compiled a C++ version of OpenCV and now when I want to run my python script i get this error:

Traceback (most recent call last): File "wiz.py", line 2, in import cv2.cv as cv ImportError: No module named cv

Check the API docs for 3.0. Some python functions return more parameters or in a different order.

example: cv2.cv.CV_HAAR_SCALE_IMAGE was replaced with cv2.CASCADE_SCALE_IMAGE

or

(cnts, _) = cv2.findContours(...) now returning the modified image as well (modImage, cnts, _) = cv2.findContours(...)
