花了兩天時間才把Openv3.1的Python安裝完成。
中間遇到了好多奇怪的錯誤，在這裏記錄下整個安裝過程。

安裝cmake-gui

這裏須要特別說明一下,這個是必定要安裝的，等會編譯的時候須要使用到它

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> yum install cmake-gui</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

爲了支持GUI特徵

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> yum install gtk2-devel</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

爲了支持攝像頭

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> yum install libdc1394-devel <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> yum install libv4l-devel</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

爲了支持視頻媒體

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">sudo yum install ffmpeg<span class="hljs-attribute" style="box-sizing: border-box;">-devel</span> sudo yum install gstreamer<span class="hljs-attribute" style="box-sizing: border-box;">-plugins</span><span class="hljs-attribute" style="box-sizing: border-box;">-base</span><span class="hljs-attribute" style="box-sizing: border-box;">-devel</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

這裏須要說明，ffmpeg其實最好是手動安裝 
這裏給出手動安裝教程鏈接手動安裝教程鏈接

順便說一句，不少人都在抱怨Centos上沒法看視頻的問題。 
其實就是沒有解碼器。 
我的建議使用vlc這個開源的視頻解碼器。

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> yum install vlc</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

須要播放視頻的時候，使用下面的命令便可

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">vlc name<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.mp</span>4</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

關於python

個人Python版本是當前最新2.7.11，集成在Anaconda中。 
我的感受這個很好用，建議你們安裝使用

由於Centos是自帶pyhton的，因此須要將Anaconda的Python添加環境變量。

在文件最後面添加：

這樣在使用python的時候用的就是Anaconda的python了。

ipp_icv下載

下載地址

這個東西是一個並行計算庫，在編譯的時候若是沒有這貨，就會編譯不經過。 
雖然能夠直接在命令中忽略這個，但我的建議仍是用上比較好

可選的依賴項

上面的那些依賴若是安裝完成後，就已經具有了安裝Opencv的基本依賴了。
根據我的須要，可能還須要安裝一些其餘的依賴，下面給出一些可選的依賴項。

圖形文件解碼庫更新

opencv自帶了一些png/jpg等圖片的解碼器，但可能有一些老了。
可使用一些比較新的圖片解碼庫：

線程構建模塊

Intel’s Threading Building Blocks (TBB),是Intel公司開發的並行編程開發的工具。 
想要使用這個的話，在Cmake的時候，須要使用參數 -D WITH_TBB=ON

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> yum install tbb-devel</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

矩陣計算

Eigen是一個開源的C++矩陣計算工具 
想要使用這個的花，在Cmake的時候，須要使用參數 -D WITH_EIGEN=ON 
固然最好的安裝方式是從源碼安裝，這裏直接用yum安裝了

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> yum install eigen3-devel</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

cuda安裝

cuda是NVIDIA推出的通用並行計算架構，該架構使GPU可以解決複雜的計算問題。 
使用C語言來爲CUDA™架構編寫程序。

個人筆記本上只有Centos系統，並非使用的虛擬機。 
若是是你使用的是虛擬機，就能夠直接跳過這個了。

Contrib modules

在opencv2.4中，opencv_contrib模塊已經集成在了其中。
可是對於opencv3.1而言，因爲這個模塊中的代碼相對不太穩定
它並無集成在opencv3.1中。[下載鏈接](https://github.com/Itseez/opencv_contrib)
強烈建議安裝opencv的時候也安裝這個。
固然，如今能夠不用安裝，畢竟東西太多就會繁瑣。
它的安裝方式在github上有詳細的說明。
若是想要安裝，可直接參考，這裏不作過多說明。

Opencv3.1編譯安裝

下載Opencv3.1

先Cmake一次

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">cmake <span class="hljs-attribute" style="box-sizing: border-box;">-D</span> CMAKE_BUILD_TYPE<span class="hljs-subst" style="color: rgb(0, 0, 0); box-sizing: border-box;">=</span>RELEASE <span class="hljs-attribute" style="box-sizing: border-box;">-D</span> CMAKE_INSTALL_PREFIX<span class="hljs-subst" style="color: rgb(0, 0, 0); box-sizing: border-box;">=</span>/usr/<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">local</span> <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">..</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

此時會發現Cmake停在了下面這個位置，直接用Ctrl+C停掉當前的Cmake

進入下面這個文件夾，會發現ippicv_linux_20151201.tgz文件

<code class="hljs has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">opencv-3.1.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

用 rm ippicv_linux_20151201.tgz，刪除這個文件。 
而後將上面ipp_icv下載中下載的文件放在這個文件夾下。

從新使用上面的命令Cmake一次。這一此Cmake能夠經過，而且也能夠做make擦做。 
可是，在Cmake提供的logout中能夠看到下面這條信息：

這裏PythonInterp和PythonLibs都不符合，會致使Python的OpenCV庫沒法編譯成功。 
可是C++的庫是沒有問題的。 
爲了讓OpenCV的Python庫能夠編譯出來，須要作下面一步：

使用Cmake-gui

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">cmake<span class="hljs-attribute" style="box-sizing: border-box;">-gui</span> <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">..</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

在cmake-gui的界面中找到python的配置選項，而且設置以下： 

你們能夠按照本身的python環境來配置這些選項。

再按Configure，就會看到以下配置，這些配置必需要有。

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"> Python <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2</span>: Interpreter: /usr/<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">local</span>/anaconda2/bin/python2<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.7</span> (ver <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2.7</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.11</span>) Libraries: /usr/<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">local</span>/anaconda2/lib/libpython2<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.7</span><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">.</span>so (ver <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2.7</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.11</span>) numpy: /usr/<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">local</span>/anaconda2/lib/python2<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.7</span>/site<span class="hljs-attribute" style="box-sizing: border-box;">-packages</span>/numpy/core/include (ver <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1.10</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.1</span>) packages path: /usr/<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">local</span>/anaconda2/lib/python2<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.7</span>/site<span class="hljs-attribute" style="box-sizing: border-box;">-packages</span> </code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

再按一下Generate，完成後就能夠退出cmake-gui了。

編譯安裝Opencv

make 編譯，後面的參數 -j8 指的是個人cpu有8線程，這個提議提升編譯的效率。 
你們須要根據本身的CPU的線程數來肯定這個值。 
固然，直接make也沒問題，就是慢一點而已。

<code class="hljs lasso has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">make <span class="hljs-attribute" style="box-sizing: border-box;">-j8</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

看到這兩句，就說明編譯成功，不然的話將上面cmke-gui的步驟再來一次。

<code class="hljs vbnet has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">Linking CXX <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">shared</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">module</span> ../../<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">lib</span>/cv2.so [<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">100</span>%] Built target opencv_python2</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

最後一行命令：

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">sudo</span> make install</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

測試Opencv

在python的編輯器中寫下面的代碼，我用的編輯器是PyCharm，感受很好用。

<code class="hljs python has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">import</span> cv2 <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">print</span> cv2.__version__</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px;  top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

輸出結果3.1.0，說明opencv的python版本，安裝成功
