  说明:

    Anaconda2-5.0.0-Windows-x86_64.exe安装下来,默认的Python2.7

    Anaconda3-4.2.0-Windows-x86_64.exe安装下来,默认的Python3.5

    Anaconda3-5.0.0-Windows-x86_64.exe安装下来,默认的Python3.6

全网最全最详细的Windows下安装Anaconda2 / Anaconda3(图文详解)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  1、  以下是在Windows下Anaconda2里正确下载安装OpenCV(离线方式)

  下载地址 

  因为python装的是Anaconda2版本,所以对应着选择,就安装

  

 

 

https://www.lfd.uci.edu/~gohlke/pythonlibs/

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

PS C:\Anaconda2\Lib\site-packages> pip install opencv_python-2.4.13.2-cp27-cp27m-win_amd64.whl
Processing c:\anaconda2\lib\site-packages\opencv_python-2.4.13.2-cp27-cp27m-win_amd64.whl
Installing collected packages: opencv-python
Successfully installed opencv-python-2.4.13.2
PS C:\Anaconda2\Lib\site-packages>

 

 

 

 

 

  测试一下,输python进入python,输入import cv2回车,不报错就说明安装配置成功了 

复制代码
PS C:\Anaconda2\Lib\site-packages> python
Python 2.7.13 |Anaconda, Inc.| (default, Sep 19 2017, 08:25:59) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> import cv2
>>>
复制代码

     对于这种方式,我尝试了,是可以行得通的。

 

 

 

 

 

 

 

 

 2、 以下是在Windows下Anaconda3里正确下载安装OpenCV(离线方式)

  下载地址 

  因为python装的是Anaconda3版本,所以对应着选择,就安装

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

PS C:\Anaconda3\Lib\site-packages> pip install opencv_python-3.3.1-cp36-cp36m-win_amd64.whl
opencv_python-3.3.1-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.
PS C:\Anaconda3\Lib\site-packages>

 

  

 

 

 

 

 

 

 

 

    如果还出现这个情况,则换个版本试试。这个很简单,尝试这个版本

 

 

 

 

 

PS C:\Anaconda3\Lib\site-packages> pip install opencv_python-3.3.0-cp36-cp36m-win_amd64.whl
Processing c:\anaconda3\lib\site-packages\opencv_python-3.3.0-cp36-cp36m-win_amd64.whl
Installing collected packages: opencv-python
Successfully installed opencv-python-3.3.0
PS C:\Anaconda3\Lib\site-packages>

     成功!这样的安装方式是没问题的。

 

  import cv2成功。

   

 

 

 

 

 

 

 

 

 

   3、以下是在Windows下Anaconda3里的envs里正确下载安装OpenCV(离线方式)

 

 

 

 

 

 

PS C:\Anaconda3\envs\python35\Lib\site-packages> pip install opencv_python-3.3.0-cp36-cp36m-win_amd64.whl
Requirement already satisfied: opencv-python==3.3.0 from file:///C:/Anaconda3/envs/python35/Lib/site-packages/opencv_python-3.3.0-cp36-cp36m-win_amd64.whl in c:\anaconda3\lib\site-packages
PS C:\Anaconda3\envs\python35\Lib\site-packages>

    一样的,因为这个envs环境是通过如下创建得到的,所以,是寄生在Anaconda3里。

 

 

 

    这种方式,也是成功的。

 

 

 

    如果大家中间有遇到如下的问题,则对应解决。

复制代码

   如果运行下来,还是没得到解决,则

 

    再尝试下,

  问题出现的原因是numpy的版本较高,不能与opencv2兼容 
解决办法: 
      pip install -U numpy 
即可将numpy恢复到合适的版本(这里为1.9.2) 
再 import cv2 就不会出现上面的问题了。

 

    成功!

 

 

 

 

 

 

    有时候,你可能得卸载Anaconda3里已经安装好了的opencv,再来安装。(为什么呢?是因为你可能没看仔细,下错版本了)

 

 

 

    成功!

 

 

 

 

 

 

    同样,对于如果你是Anaconda3-4.2.0-Windows-x86_64.exe安装下来,默认的Python3.5,则如下

 

 

   成功!

 

 

 

 

 

 

  4、以下是在Windows下Anaconda3里正确下载安装OpenCV(在线方式)(注意这里有坑,一定要按照我的来)

     可以看到,如果你是直接这么来安装,是错误的。为什么呢?按照我的来,先卸载吧。

         需要源文件安装,通过,pip一般都是失败的(经过验证,需要处理下)
 

    于是,我把它给卸载了,带大家来重新做一遍。

 
 

 

 解决办法:

  https://github.com/skvark/opencv-python/issues/36

 

 

     什么意思,很简单。

    (1)下载安装 Visual C++ Redistributable for Visual Studio 2015  不难,别嫌麻烦。

      (2) 把下载的python3.dll放到你所安装Anaconda3的目录下即可。

 

     我的是这样的。

 

 

 

     然后,再尝试pip  install  opencv-python执行完后,再import  cv2就可以成功了

    成功!

 

 

 

 

 

 

 

 

 

 

  5、也可以直接在Pycharm里搜索并安装Opencv

   这个不多赘述

 

 

 

 

 

 

 

 

 

 

 

总结

    很多人写的对于OpenCV都是冰山一角,其实没有大家想的那么复杂,只是没有多尝试罢了。

    无论是Python2还是Python3系列,都可以安装,且离线和在线安装成功。

    提醒的是,注意对应自己的版本去安装。
