前幾天剛安裝OpenCV for Python, 今天準備測試時發生錯誤訊息
import cv2
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-72fbbcfe2587> in <module>()
----> 1 import cv2
ImportError: DLL load failed: 找不到指定的程序。
上網google到這一篇[1]看起來跟我的狀況很類似,
學習新工具建立環境總是會遇到一些奇奇怪怪的狀況, 真是考驗人的耐心….
-----------------------------------------------------------
下載並解壓縮OpenCV2.4.13
開啟C:\OpenCV\OpenCV2.4.13\opencv\build\python\2.7\x86
複製cv2.pyd
貼上cv2.pyd
新增系統變數OpenCV2413
![image_thumb1[1]](http://pic.pimg.tw/me1237guy/1480838780-1906781696.png "image_thumb1[1]")
開啟Path系統變數, 然後<新增>%OpenCV2413%
