安装opencv无法使用import cv2

---

为了在python里面使用cv2，安装opencv3.0折腾了几天，后来才发现3.0无法生成cv2.so，于是改成了2.×的版本 1、手动下载并解压opencv2.49 2、安装依赖的库

sudo apt-get install build-essential cmake libgtk2.0-dev pkg-config python-dev python-numpy libavcodec-dev libavformat-dev libswscale-dev

3、安装opencv

cd opencv2.49 mkdir build cd build cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. make sudo make install

3、拷贝cv2.so

cp /usr/local/lib/python2.7/site-packages/cv* /path-to-anaconda2/lib/python2.7/site-packages/
