環境設定

Step 1: 安裝Python

到https://www.python.org/ 下載並安裝Python 2.7版，更新的版本OpenCV 2並不支援。

Step 2: 安裝Libraries

將" D:\project\opencv\build\python\2.7″或" D:\project\opencv\build\python\2.7\x86″內的所有檔案放到"D:\Python27\Lib\site-packages"

Step 3: 下載NumPy

NumPy是OpenCV需要用到的extension，如安裝的是32-bit版Python，可到https://pypi.python.org/pypi/numpy下載CP27版的NumPy，64-bit版則需要到http://www.lfd.uci.edu/~gohlke/pythonlibs/下載非官方版。

Step 4: 安裝NumPy

將下載回來的.whl檔放到"D:\Python27\Scripts"，透過cmd執行同位置的pip2.7.exe，加入該.whl檔作為argument，pip就會安裝好NumPy

 

Download numpy-1.9.2+mkl-cp27-none-win32.whl fromhttp://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy .

Copy the file to D:\Python27\Scripts

Run cmd from the above location and type

pip install numpy-1.9.2+mkl-cp27-none-win32.whl

You will hopefully get the below output:

Processing D:\python27\scripts\numpy-1.9.2+mkl-cp27-none-win32.whl

Installing collected packages: numpy

Successfully installed numpy-1.9.2

Step 5: 測試匯入

Step 6: 安裝matplotlib

Download matplotlib-1.4.3-cp27-none-win_amd64.whl

http://matplotlib.org/downloads.html

使用PIP安裝，Fail

再下載matplotlib-1.4.3.win-amd64-py2.7.exe

執行安裝, package會在D:\Python27\Lib\site-packages
