我如何安装OpenCV？

Question

Im trying to install OpenCV package for Python on my debian. I ran sudo apt-get install python-opencv and accepted it.

But when I import cv my application says that there is no module named cv :(

import cv was fetched from a tutorial. What is the correct syntax?

Answer 2

The correct import is

import cv2

Also, I've been doing a lot of opencv in python this month, and found this was a great tutorial for getting started: http://trevorappleton.blogspot.com/2013/11/python-getting-started-with-opencv.html
