三種方法：
1. pip 安裝 ：
pip install opencv-python ，最新版為opencv3>>> import cv2
>>> print cv2.__version__參考：http://www.cnblogs.com/lclblack/p/6377710.html
2. anaconda的conda安裝 ,可以指定opencv版本，如opencv2
conda install -c https://conda.binstar.org/menpo opencv=2.4.9但是容易出問題，比如 /lib64/libc.so.6: version `GLIBC_2.14' not found問題 ，可以參考如下鏈接升級

可能導致奔潰，所以請小心安裝。
3. 源碼裝
https://docs.opencv.org/3.0-beta/doc/py_tutorials/py_setup/py_setup_in_fedora/py_setup_in_fedora.html#install-opencv-python-in-fedora
裝完后，
Installation is over. All files are installed in?/usr/local/?folder. But to use it, your Python should be able to find OpenCV module. You have two options for that.
-
Move the module to any folder in Python Path?: Python path can be found out by entering?import?sys;printsys.path?in Python terminal. It will print out many locations. Move?/usr/local/lib/python2.7/site-packages/cv2.so?to any of this folder. For example,
But you will have to do this every time you install OpenCV.
-
Add ``/usr/local/lib/python2.7/site-packages`` to the PYTHON_PATH: It is to be done only once. Just open?~/.bashrc?and add following line to it, then log out and come back.
Thus OpenCV installation is finished. Open a terminal and try?import?cv2.

4. python的測試

linux下查看opencv版本

5. 覆蓋原有opencv
?如果服務器已經安裝了opencv,但是通過anaconda的conda安裝，也安裝了python的opencv接口，會發現其中也包含了opencv的lib,include文件，如下：
這時可以使用這個版本的opencv覆蓋原裝的，方法是修改bashrc,如下：
## 動態庫搜索路徑 export LD_LIBRARY_PATH=/home/caiyong.wang/anaconda2/lib:$LD_LIBRARY_PATH
##(靜態庫搜索路徑) 程序編譯期間查找動態鏈接庫時指定查找共享庫的路徑export LIBRARY_PATH=/home/caiyong.wang/anaconda2/lib:$LIBRARY_PATH ##c程序頭文件搜索路徑export C_INCLUDE_PATH=/home/caiyong.wang/anaconda2/include:$C_INCLUDE_PATH
##c++程序頭文件搜索路徑export CPLUS_INCLUDE_PATH=/home/caiyong.wang/anaconda2/include:$CPLUS_INCLUDE_PATH
##pkg-config 路徑export PKG_CONFIG_PATH=/home/caiyong.wang/anaconda2/lib/pkgconfig/:$PKG_CONFIG_PATH可以使用原方法測試。
