Installing OpenCV on Windows 7 for Python 2.7

Question

am trying desperately to get OpenCV to work on Windows 7. I download and installed it, and it didn't work, I got

ImportError: No module named opencv 

when I tried to run one of the samples. I google my problem and got only random solutions that don't work. Can anybody guide me in installing it, or know where i can get a clear installation guide design for a programming noob.

As of OpenCV 2.2.0, the package name for the Python bindings is "cv".The old bindings named "opencv" are not maintained any longer. You might have to adjust your code. See http://opencv.willowgarage.com/wiki/PythonInterface.

The official OpenCV installer does not install the Python bindings into your Python directory. There should be a Python2.7 directory inside your OpenCV 2.2.0 installation directory. Copy the whole Lib folder from OpenCVPython2.7 to C:Python27 and make sure your OpenCVin directory is in the Windows DLL search path.

Alternatively use the opencv-python installers at http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv.
