1.安装Ubuntu16.04 LTS x64
利用工具rufus制作USB系统盘(官方下载64位版本: ubuntu-16.04-desktop-amd64.iso)，因为已有Win7系统，此处选择“Install Ubuntu alongside Windows Boot Manager”，分区采用默认选择，语言选择English，安装完毕。
注：此时显示器VGA接口接到主板集成显卡接口上。
2.更新源
cd /etc/apt/ sudo cp sources.list sources.list.bak sudo gedit sources.list在sources.list文件头部添加如下源：
deb http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse然后更新源和安装的包:
sudo apt-get update sudo apt-get upgrade3.安装NVIDIA显卡驱动
采用ppa安装方式，没选择最新的nvidia-370，我选择了nvidia-367。
Ctrl+Alt+F1进入tty命令控制台，停止lightdm，然后开始安装驱动。
sudo services lightdm stop sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get updates sudo apt-get install nvidia-367 sudo apt-get install mesa-common-dev sudo apt-get install freeglut3-dev sudo reboot将显示器VGA接口换到NVIDIA显卡上。
4.修改分辨率
启动到界面之后发现分辨率只有1366x768，显示器适合1920x1080，采用xrandr并修改xorg.conf来解决。
sudo gedit /etc/X11/xorg.conf 修改如下： HorizSync 31.0 - 84.0 VertRefresh 56.0-77.0即最终的xorg.conf文件为：
Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Configured Monitor" Horizsync 30-84 Vertrefresh 56-77 EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Modes "1920x1080" "1360x768" "1024x768" "1152x864" EndSubSection EndSection注销系统再次登录后，选择适合的桌面分辨率即可。
5.安装CUDA8.0
到官网下载cuda_8.0.44_linux.run，复制到根目录下。
sudo sh cuda_8.0.44_linux.run --tmpdir=/tmp/遇到问题：incomplete installation，然后执行
sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev sudo sh cuda_8.0.44_linux.run -silent -driver注：此时安装过程中提示是否要安装NVIDIA驱动时选择no。其他选择yes或默认即可。
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 361.62? (y)es/(n)o/(q)uit: n安装完毕后声明环境变量：
sudo gedit ~/.bashrc在.bashrc尾部添加如下内容：
export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}} export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}测试下安装是否成功：

#include "precomp.hpp" #if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION >= 8000)because graphcuts is not supported directly with CUDA8 anymore.
安装成功后配置环境：
sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf' sudo ldconfig测试OpenCV安装是否成功：
mkdir DisplayImage cd DisplayImage gedit DisplayImage.cpp添加代码：

从官网下载cudnn-8.0-linux-x64-v5.1.tgz for CUDA 8.0. 解压到当前目录：
tar -zxvf cudnn-8.0-linux-x64-v5.1.tgz解压后的文件如下：
cuda/include/cudnn.h cuda/lib64/libcudnn.so cuda/lib64/libcudnn.so.5 cuda/lib64/libcudnn.so.5.1.5 cuda/lib64/libcudnn_static.a然后执行：
sudo cp cuda/include/cudnn.h /usr/local/cuda/include/ sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/ sudo chmod a+r /usr/local/cuda/include/cudnn.h sudo chmod a+r /usr/local/cuda/lib64/libcudnn*8.安装MATLAB 2014a
需要注意的是Ubuntu16.04 LTS的gcc版本为5.4，而Matlab2014a支持的是gcc4.7。
用Crack文件中的install替换matlab2014安装目录下/java/jar/下的install文件，然后执行install程序
cd "MatlabFolder" sudo ./install注意：选择“不联网安装”；当出现密钥时，随意输入20个数字12345-67890-12345-67890即可；需要激活时选择不要联网激活，用Crack目录下的“license_405329_R2014a.lic”文件激活。
安装完成之后，将Crack/Linux目录下的libmwservices.so文件拷贝到/usr/local/MATLAB/R2014a/bin/glnxa64。
cd .. cd Crack/Linux/ sudo cp libmwservices.so /usr/local/MATLAB/R2014a/bin/glnxa64打开Matlab并激活：
cd /usr/local/MATLAB/R2014a/bin sudo ./matlab # sudo不可缺少，否则选择激活文件后报错9.Python
选用Ubuntu16.04默认的安装和配置，python版本2.7.12.
10.BLAS安装与配置
BLAS（基础线性代数集合）是一个应用程序接口的标准。caffe官网上推荐了三种实现：ATLAS, MKL, OpenBLAS。其中ATLAS可以直接通过命令行安装。MKL是微软开发的商业工具包，面向科研和学生免费开放。申请学生版的Parallel Studio XE Cluster Edition，下载parallel_studio_xe_2017.tgz。注意接收邮件中的序列号(2HWS-34Z7S69B)。
tar zxvf parallel_studio_xe_2017.tgz #解压下载文件 chmod 777 parallel_studio_xe_2017 -R #获取文件权限 cd parallel_studio_xe_2017/ sudo ./install_GUI.sh安装完成之后，进行相关文件的链接：
sudo gedit /etc/ld.so.conf.d/intel_mkl.conf添加库文件:
/opt/intel/lib/intel64 /opt/intel/mkl/lib/intel64编译链接使lib文件生效：
sudo ldconfig如果选择安装ATLAS，在终端输入sudo apt-get install libatlas-base-dev即可。
11.Caffe的安装与配置
Caffe是由BVLC开发的一个深度学习框架，主要由贾扬清在UC Berkeley攻读PhD期间完成。参考官网上的教程以及Github上针对Ubuntu15.04和16.04的教程。从官方下载caffe源包caffe-master。

在使用Matlab运行caffe库时，即运行文件”caffe-master/matlab/demo/classification_demo.m”。遇到的错误信息如下：
Invalid MEX-file 'caffe-master/matlab/+caffe/private/caffe_.mexa64': libcudart.so.8.0: cannot open shared object file: No such file or directory错误原因是由于Matlab找不到caffe.mexa64所依赖的所有库文件的路径，此时可以使用ldd命令来查看caffe\.mexa64内库文件的地址：
//1. 在Ubuntu系统的命令终端
ldd *caffe_.mexa64结果输出的是库文件对应的地址，与下文相对的缺失的库文件的地址可在此找到：

!ldd *caffe_.mexa64结果在Matlab窗口的输出信息中发现：
libcudart.so.8.0 => not found libcublas.so.8.0 => not found libcurand.so.8.0 => not found libcudnn.so.5 => not found解决方法：通过如下命令将默认路径链接到真实路径下：

另外，运行此例需要下载CaffeNet模型（Please download CaffeNet from Model Zoo before you run this demo.）https://github.com/BVLC/caffe/wiki/Model-Zoo
