Opencv3.1+python2.7的CentOS7安装

http://blog.csdn.NET/daunxx/article/details/50506625

转载注释：有些包名和系统包名并不匹配，yum install 找不到的时候，可以yum search一下。比如gtk2-devel和gstreamer-plugins-base-devel

花了两天时间才把Openv3.1的Python安装完成。
中间遇到了好多奇怪的错误，在这里记录下整个安装过程。

安装cmake-gui

这里需要特别说明一下,这个是一定要安装的，等会编译的时候需要使用到它

<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>

为了支持GUI特征

<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>

为了支持摄像头

<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>

为了支持视频媒体

<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>

这里需要说明，ffmpeg其实最好是手动安装 
这里给出手动安装教程连接手动安装教程连接

顺便说一句，很多人都在抱怨Centos上无法看视频的问题。 
其实就是没有解码器。 
个人建议使用vlc这个开源的视频解码器。

<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>

需要播放视频的时候，使用下面的命令即可

<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>

关于python

我的Python版本是当前最新2.7.11，集成在Anaconda中。 
个人感觉这个很好用，建议大家安装使用

因为Centos是自带pyhton的，所以需要将Anaconda的Python添加环境变量。

在文件最后面添加：

这样在使用python的时候用的就是Anaconda的python了。

ipp_icv下载

下载地址

这个东西是一个并行计算库，在编译的时候如果没有这货，就会编译不通过。 
虽然可以直接在命令中忽略这个，但个人建议还是用上比较好

可选的依赖项

上面的那些依赖如果安装完成后，就已经具备了安装Opencv的基本依赖了。
根据个人需要，可能还需要安装一些其他的依赖，下面给出一些可选的依赖项。

图形文件解码库更新

opencv自带了一些png/jpg等图片的解码器，但可能有一些老了。
可以使用一些比较新的图片解码库：

<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 libpng<span class="hljs-attribute" style="box-sizing: border-box;">-devel</span> sudo yum install libjpeg<span class="hljs-attribute" style="box-sizing: border-box;">-turbo</span><span class="hljs-attribute" style="box-sizing: border-box;">-devel</span> sudo yum install jasper<span class="hljs-attribute" style="box-sizing: border-box;">-devel</span> sudo yum install openexr<span class="hljs-attribute" style="box-sizing: border-box;">-devel</span> sudo yum install libtiff<span class="hljs-attribute" style="box-sizing: border-box;">-devel</span> sudo yum install libwebp<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><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>

线程构建模块

Intel’s Threading Building Blocks (TBB),是Intel公司开发的并行编程开发的工具。 
想要使用这个的话，在Cmake的时候，需要使用参数 -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>

矩阵计算

Eigen是一个开源的C++矩阵计算工具 
想要使用这个的花，在Cmake的时候，需要使用参数 -D WITH_EIGEN=ON 
当然最好的安装方式是从源码安装，这里直接用yum安装了

<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安装

cuda是NVIDIA推出的通用并行计算架构，该架构使GPU能够解决复杂的计算问题。 
使用C语言来为CUDA™架构编写程序。

我的笔记本上只有Centos系统，并不是使用的虚拟机。 
如果是你使用的是虚拟机，就可以直接跳过这个了。

Contrib modules

在opencv2.4中，opencv_contrib模块已经集成在了其中。
但是对于opencv3.1而言，由于这个模块中的代码相对不太稳定
它并没有集成在opencv3.1中。[下载连接](https://github.com/Itseez/opencv_contrib)
强烈建议安装opencv的时候也安装这个。
当然，现在可以不用安装，毕竟东西太多就会繁琐。
它的安装方式在github上有详细的说明。
如果想要安装，可直接参考，这里不做过多说明。

Opencv3.1编译安装

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>

此时会发现Cmake停在了下面这个位置，直接用Ctrl+C停掉当前的Cmake

进入下面这个文件夹，会发现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，删除这个文件。 
然后将上面ipp_icv下载中下载的文件放在这个文件夹下。

重新使用上面的命令Cmake一次。这一此Cmake可以通过，并且也可以作make擦作。 
但是，在Cmake提供的logout中可以看到下面这条信息：

这里PythonInterp和PythonLibs都不符合，会导致Python的OpenCV库无法编译成功。 
但是C++的库是没有问题的。 
为了让OpenCV的Python库可以编译出来，需要做下面一步：

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的配置选项，并且设置如下： 

大家可以按照自己的python环境来配置这些选项。

再按Configure，就会看到如下配置，这些配置必须要有。

<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，完成后就可以退出cmake-gui了。

编译安装Opencv

make 编译，后面的参数 -j8 指的是我的cpu有8线程，这个提议提高编译的效率。 
大家需要根据自己的CPU的线程数来确定这个值。 
当然，直接make也没问题，就是慢一点而已。

<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>

看到这两句，就说明编译成功，否则的话将上面cmke-gui的步骤再来一次。

<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>

最后一行命令：

<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>

测试Opencv

在python的编辑器中写下面的代码，我用的编辑器是PyCharm，感觉很好用。

<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>

输出结果3.1.0，说明opencv的python版本，安装成功
