Python的OpenCV安装问题

Question

I am trying to install OpenCV on my Ubuntu system. I followed the steps of this page . I am able to run the demos for C/C++ etc. But when I try to run the python demos, I get an ImportError: No module named cv2

Here is more info :

python --version Python 2.7.8 :: Anaconda 2.1.0 (64-bit)

python -c 'import sys; print sys.path' ['', '/home/radar/anaconda/lib/python2.7/site-packages/pydy-0.2.1-py2.7.egg', '/home/radar', '/home/radar/opencv-2.4.9/modules/python/src2', '/home/radar/anaconda/lib/python27.zip', '/home/radar/anaconda/lib/python2.7', '/home/radar/anaconda/lib/python2.7/plat-linux2', '/home/radar/anaconda/lib/python2.7/lib-tk', '/home/radar/anaconda/lib/python2.7/lib-old', '/home/radar/anaconda/lib/python2.7/lib-dynload', '/home/radar/anaconda/lib/python2.7/site-packages', '/home/radar/anaconda/lib/python2.7/site-packages/PIL', '/home/radar/anaconda/lib/python2.7/site-packages/Sphinx-1.2.3-py2.7.egg', '/home/radar/anaconda/lib/python2.7/site-packages/runipy-0.1.1-py2.7.egg', '/home/radar/anaconda/lib/python2.7/site-packages/setuptools-5.8-py2.7.egg']

You are running Anaconda Python distribution, but you need to use native python to access openCV library. Run Python with specified path and it should work:

/usr/bin/python

Also note, that to use openCV with virtual environmet, you need to manually copy openCV running objects ( cv.py , cv2.so ) to the environment you are going to use from the dist-packages of your native python, default path is /usr/local/lib/python2.7/dist-packages/ .
