在Windows 7上为Python 2.7安装OpenCV

am trying desperately to get OpenCV to work on Windows 7. I download and installed it, and it didn't work, I got

我正拼命地让OpenCV在Windows 7上运行。我下载并安装它,它没有用,我得到了

ImportError: No module named opencv

when I tried to run one of the samples. I google my problem and got only random solutions that don't work. Can anybody guide me in installing it, or know where i can get a clear installation guide design for a programming noob.

当我试图运行其中一个样本时。我谷歌我的问题,只得到无效的随机解决方案。任何人都可以指导我安装它,或者知道我可以在哪里获得编程菜单的明确安装指南设计。

As of OpenCV 2.2.0, the package name for the Python bindings is "cv".The old bindings named "opencv" are not maintained any longer. You might have to adjust your code. See http://opencv.willowgarage.com/wiki/PythonInterface.

从OpenCV 2.2.0开始,Python绑定的包名称为“cv”。名为“opencv”的旧绑定不再维护。您可能需要调整代码。请参见http://opencv.willowgarage.com/wiki/PythonInterface。

The official OpenCV installer does not install the Python bindings into your Python directory. There should be a Python2.7 directory inside your OpenCV 2.2.0 installation directory. Copy the whole Lib folder from OpenCV\Python2.7\ to C:\Python27\ and make sure your OpenCV\bin directory is in the Windows DLL search path.

官方OpenCV安装程序不会将Python绑定安装到Python目录中。 OpenCV 2.2.0安装目录中应该有一个Python2.7目录。将整个Lib文件夹从OpenCV \ Python2.7 \复制到C:\ Python27 \,并确保您的OpenCV \ bin目录位于Windows DLL搜索路径中。

Alternatively use the opencv-python installers at http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv.

或者使用http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv上的opencv-python安装程序。

I have posted a very simple method to install OpenCV 2.4 for Python in Windows here : Install OpenCV in Windows for Python

我已经发布了一个非常简单的方法来在Windows中安装OpenCV 2.4 for Python:在Windows中为Python安装OpenCV

It is just as simple as copy and paste. Hope it will be useful for future viewers.

它就像复制和粘贴一样简单。希望它对未来的观众有用。

Download Python, Numpy, OpenCV from their official sites.

从他们的官方网站下载Python,Numpy,OpenCV。
Extract OpenCV (will be extracted to a folder opencv)

提取OpenCV(将解压缩到opencv文件夹)
Copy ..\opencv\build\python\x86\2.7\cv2.pyd
Paste it in C:\Python27\Lib\site-packages

将其粘贴到C:\ Python27 \ Lib \ site-packages中
Open Python IDLE or terminal, and type

打开Python IDLE或终端,然后输入
```
>>> import cv2
```

If no errors shown, it is OK.

如果没有显示错误,则可以。

If you are using the VideoCapture feature, you must copy opencv_ffmpeg.dll into your path as well. See: https://*.com/a/11703998/1134940

如果您使用的是VideoCapture功能,则还必须将opencv_ffmpeg.dll复制到路径中。请参阅:https://*.com/a/11703998/1134940

Actually you can use x64 and Python 2.7. This is just not delivered in the standard OpenCV installer. If you build the libraries from the source (http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_install/windows_install.html) or you use the opencv-python from cgohlke's comment, it works just fine.

实际上你可以使用x64和Python 2.7。这不是标准的OpenCV安装程序。如果你从源代码构建库(http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_install/windows_install.html)或者你使用cgohlke评论中的opencv-python,它就可以了。

download the opencv 2.2 version from https://sourceforge.net/projects/opencvlibrary/files/opencv-win/

从https://sourceforge.net/projects/opencvlibrary/files/opencv-win/下载opencv 2.2版本

install package.

then Copy cv2.pyd to C:/Python27/lib/site-packeges.

然后将cv2.pyd复制到C:/ Python27 / lib / site-packeges。

and it should work:

它应该工作:

import cv2

#6

open command prompt and run the following commands (assuming python 2.7):

打开命令提示符并运行以下命令(假设python 2.7):

cd c:\Python27\scripts\
pip install opencv-python

the above works for me for python 2.7 on windows 10 64 bit

以上适用于Windows 10 64位的python 2.7

One thing that needs to be mentioned. You have to use the x86 version of Python 2.7. OpenCV doesn't support Python x64. I banged my head on this for a bit until I figured that out.

有一件事需要提及。您必须使用x86版本的Python 2.7。 OpenCV不支持Python x64。在我想出这个问题之前,我把头撞了一下。

That said, follow the steps in Abid Rahman K's answer. And as Antimony said, you'll need to do a 'from cv2 import cv'

也就是说,按照Abid Rahman K的回答中的步骤进行操作。正如锑所说,你需要做一个'来自cv2 import cv'
