  一、  如下是在Windows下Anaconda2里正確下載安裝OpenCV(離線方式)機器學習

  下載地址 ide

  由於python裝的是Anaconda2版本,因此對應着選擇,就安裝post

  

 

 

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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

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>

 

 

 

 

 

  測試一下,輸python進入python,輸入import cv2回車,不報錯就說明安裝配置成功了 

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
>>>

     對於這種方式,我嘗試了,是能夠行得通的。

 

 

 

 

 

 

 

 

 二、 如下是在Windows下Anaconda3里正確下載安裝OpenCV(離線方式)

  下載地址 

  由於python裝的是Anaconda3版本,因此對應着選擇,就安裝

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

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>

 

  

 

 

 

 

 

 

 

 

    若是還出現這個狀況,則換個版本試試。這個很簡單,嘗試這個版本

 

 

 

 

 

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!這樣的安裝方式是沒問題的。

 

  import cv2成功。

   

 

 

 

 

 

 

 

 

 

   三、如下是在Windows下Anaconda3裏的envs里正確下載安裝OpenCV(離線方式)

 

 

 

 

 

 

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>

    同樣的,由於這個envs環境是經過以下建立獲得的,因此,是寄生在Anaconda3裏。

 

 

 

    這種方式,也是成功的。

 

 

 

    若是你們中間有遇到以下的問題,則對應解決。

   若是運行下來,仍是沒獲得解決,則

 

    再嘗試下,

  問題出現的緣由是numpy的版本較高,不能與opencv2兼容 
  解決辦法: 
      pip install -U numpy 
  便可將numpy恢復到合適的版本(這裏爲1.9.2) 
  再 import cv2 就不會出現上面的問題了。

 

    成功!

 

 

 

 

 

 

    有時候,你可能得卸載Anaconda3裏已經安裝好了的opencv,再來安裝。(爲何呢?是由於你可能沒看仔細,下錯版本了)

 

 

 

    成功!

 

 

 

 

 

 

    一樣,對於若是你是Anaconda3-4.2.0-Windows-x86_64.exe安裝下來,默認的Python3.5,則以下

 

 

   成功!

 

 

 

 

 

 

  四、如下是在Windows下Anaconda3里正確下載安裝OpenCV(在線方式)(注意這裏有坑,必定要按照個人來)

     能夠看到,若是你是直接這麼來安裝,是錯誤的。爲何呢?按照個人來,先卸載吧。

         須要源文件安裝,經過,pip通常都是失敗的(通過驗證,須要處理下)
 

    因而,我把它給卸載了,帶你們來從新作一遍。

 
 

 

 解決辦法:

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

 

 

     什麼意思,很簡單。

    (1)下載安裝 Visual C++ Redistributable for Visual Studio 2015  不難,別嫌麻煩。

      (2) 把下載的python3.dll放到你所安裝Anaconda3的目錄下便可。

 

     個人是這樣的。

 

 

 

     而後,再嘗試pip  install  opencv-python執行完後,再import  cv2就能夠成功了

    成功!

 

 

 

 

 

 

 

 

 

 

  五、也能夠直接在Pycharm裏搜索並安裝Opencv

   這個很少贅述

 

 

 

 

 

 

 

 

 

 

 

總結

    不少人寫的對於OpenCV都是冰山一角,其實沒有你們想的那麼複雜,只是沒有多嘗試罷了。

    不管是Python2仍是Python3系列,均可以安裝,且離線和在線安裝成功。

    提醒的是,注意對應本身的版本去安裝。
