问题描述
我已经下载了OpenCV2.1和Python2.6.
I have downloaded OpenCV2.1 and Python2.6.
当我尝试先使用sys.path.append("C:\OpenCV2.1\Python2.6\Lib\site-packages")然后import cv尝试import cv时，它会告诉我ImportError: DLLload failed..
when i try to import cv using sys.path.append("C:\OpenCV2.1\Python2.6\Lib\site-packages") and then import cv, it tells me ImportError: DLLload failed..
我尝试了上一个线程中给出的解决方案，将上述路径中的两个文件复制到C:\Python26\Lib\site-packages，但是我仍然不能import cv.
I have tried the solutions given in previous thread to copy the two files in the above path to C:\Python26\Lib\site-packages, but i still can't import cv.
是因为我错过了安装后的一些步骤吗?系统找不到模块cv的原因可能是什么?
Is it because I missed out doing some steps after installing? What could be the reasons to why the system cannot find the module cv?
推荐答案
似乎找不到OpenCV DLL.您是否将OpenCV的bin目录添加到您的PATH和"C:\OpenCV2.1\bin"中?
The OpenCV DLLs seem not to be found. Did you add OpenCV's bin directory to your PATH, "C:\OpenCV2.1\bin" in your case?
使用Python包装器
To use the Python wrappers
sys.path.append("C:\OpenCV2.1\Python2.6\Lib\site-packages")
import cv
应该起作用，并将cv.lib和cv.pyd复制到您的C:\Python26\Lib\site-packages(假设您已将Python安装到C:\Python26).
should work, as well as copying cv.lib and cv.pyd to your C:\Python26\Lib\site-packages (assuming you installed Python to C:\Python26).
但是那些包装器必须找到应该包装的DLL.因此，请确保它们在Python可以找到它们的路径中.
But those wrappers have to find the DLLs they should wrap. So make sure, they are in a path Python can find them.
也许这个问题在Windows 7上为Python 2.7安装OpenCV 可能会有所帮助，尤其是 Gia Thuy的他在回答中提到的日记帖子.尽管他使用Python 2.7和OpenCV 2.2，但过程仍然相同.
Maybe this question Installing OpenCV on Windows 7 for Python 2.7 may help, especially Gia Thuy's journal post he mentions in his answer. Although he uses Python 2.7 and OpenCV 2.2, the procedure remains the same.
