ubuntu14.04+cuda8.0（GTX1080）+caffe安装

1、 ubuntu14.04安装
分区：usr/local 300G
boot 200M
/ 根目录 300G
交换空间 20G （内存16G）
其余都是/home
重装之后，下载NVIDIA-Linux-x86_64-367.27.run，下载地址为：http://www.geforce.cn/drivers/results/104314
将其与cuda_8.0.27_linux.run（下载地址为：https://developer.nvidia.com/cuda-toolkit 不过需要注册）拷到home/zhou下。

2、NVIDIA 驱动安装
1) Ctrl+alt+F1进入字符界面，关闭图形界面
sudo service lightdm stop //必须有，不然会安装失败
2) 安装nvidia driver

sudo chmod 755 NVIDIA-Linux-x86_64-367.27.run  //获取权限
sudo ./NVIDIA-Linux-x86_64-367.27.run  //安装驱动

Accept
Continue installation
安装完成之后

sudo service lightdm start

图形界面出现，然后关机，切换到1080

3、 Cuda8.0安装
开机（桌上桌下来回窜，还好我比较瘦==。）
1) 在终端运行指令 sudo sh cuda_8.0.27_linux.run
选择
Do you accept the previously read EULA?
accept/decline/quit: accept

Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 361.62?
(y)es/(n)o/(q)uit: n

Install the CUDA 8.0 Toolkit?
(y)es/(n)o/(q)uit: y

Enter Toolkit Location
[ default is /usr/local/cuda-8.0 ]:

Do you want to install a symbolic link at /usr/local/cuda?
(y)es/(n)o/(q)uit: y

Install the CUDA 8.0 Samples?
(y)es/(n)o/(q)uit: y

Enter CUDA Samples Location
[ default is /home/zhou ]:

Installing the CUDA Toolkit in /usr/local/cuda-8.0 …
Missing recommended library: libGLU.so
Missing recommended library: libX11.so
Missing recommended library: libXi.so
Missing recommended library: libXmu.so

Installing the CUDA Samples in /home/zhou …
Copying samples to /home/zhou/NVIDIA_CUDA-8.0_Samples now…
Finished copying samples.

===========
= Summary =
===========
Driver: Not Selected
Toolkit: Installed in /usr/local/cuda-8.0
Samples: Installed in /home/zhou, but missing recommended libraries

Please make sure that
- PATH includes /usr/local/cuda-8.0/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-8.0/lib64, or, add /usr/local/cuda-8.0/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-8.0/bin

Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-8.0/doc/pdf for detailed information on setting up CUDA.

***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 361.00 is required for CUDA 8.0 functionality to work.
To install the driver using this installer, run the following command, replacing with the name of this run file:
sudo .run -silent -driver

Logfile is /tmp/cuda_install_2961.log
安装完成，但是缺少一些库。

2) 安装所缺少的库

sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev

这个因为网络问题，可能要安装很久。
还是有线好点。

3)

sudo apt-get install vim

安装完成。

4) 设置环境变量
在终端输入这两句：

export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH

然后修改文件中环境变量设置

sudo vi /etc/profile

输入上面export的两句，保存，退出。

sudo ldconfig //环境变量立即生效

5) 验证安装是否完成

nvidia-smi 

显示：

nvcc –V

显示：

nvcc -V nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2016
NVIDIA Corporation Built on Wed_May__4_21:01:56_CDT_2016 Cuda
compilation tools, release 8.0, V8.0.26

6) 测试cuda的samples

cd ‘/home/zhou/NVIDIA_CUDA-8.0_Samples’
make 

也不知道是我的错觉还是什么的，比以前快很多啊，大概等7分钟左右吧。（听了两首薛之谦的新歌）

7) 安装cudnn5.0
安装cuDNN比较简单，解压后把相应的文件拷贝到对应的CUDA目录下即可：

tar -zxvf cudnn-8.0-linux-x64-v5.0-ga.tgz

显示以下信息：
*cuda/include/cudnn.h
cuda/lib64/libcudnn.so
cuda/lib64/libcudnn.so.5
cuda/lib64/libcudnn.so.5.0.5
cuda/lib64/libcudnn_static.a*
继续执行以下指令：

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) 验证一下，哈哈哈哈哈啊哈哈哈哈哈
cuda的samples 里面有个deviceQuery 运行之后会显示信息，最后一行出行pass说明成功啦～～～～

4、matlab安装
1）先获取root权限

sudo su

2）然后按照以前的步骤来，不过这次没有创建快捷方式，因为根本没用过==。
下载完成后将iso文件挂载到Linux

sudo mkdir /media/matlab
mount -o loop [path][filename].iso /media/matlab
cd /media/matlab
sudo ./install

进行安装，安装路径：/usr/local/MATLAB/R2014a
PS：需要注意的是，我下载到的文件里面 readme.txt里没有序列号，所以我就随便填了一个
选项：不使用Internet安装
序列号： 12345-67890-09876-54321
默认路径：/usr/local/MATLAB/R2014a
勾选从默认启动路径创建符号链接（实现在任意位置运行matlab启动程序）
3）激活，选择离线激活模式，选择crack文件夹下的license_405329_R2014a.lic文件进行激活。
4）破解 将crack文件夹下的libmwservices.so 复制到/usr/local/MATLAB/R2014A/bin/glnxa64

sudo cp libmwservices.so /usr/local/MATLAB/R2014a/bin/glnxa64/ 

5）完成安装，命令行下使用sudo matlab即可启动使用

5、 caffe 安装
这里是跟着官网教程来的
1) 安装依赖项

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler

sudo apt-get install --no-install-recommends libboost-all-dev

2) BLAS安装

sudo apt-get install libatlas-base-dev

3) 安装pycaffe接口所需要的依赖项

sudo apt-get install -y python-numpy python-scipy python-matplotlib python-sklearn python-skimage python-h5py python-protobuf python-leveldb python-networkx python-nose python-pandas python-gflags cython ipython

4) 继续安装依赖项

sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev

5) opencv3.0安装
参照http://ouxinyu.github.io/Blogs/20151108001.html
（1）使用他提供的修改版的安装包(即百度云下载，密码：wysa)（下面的安装方式使用该包完成，安装包修改了dependencies.sh文件并增加了OpenCV 3.0.0的安装文件）
（2）切换到文件保存的文件夹（/home/zhou/opencv3.0），然后安装依赖项
sudo sh dependencies.sh
（3）安装OpenCV3.0
sudo sh opencv3_0_0.sh
==。 就应该直接自己下载文件的，我这渣网速。
虽然最后下完了，但是在半路又需要下载文件ippicv_linux_20141027.tgz
因为网络不稳定，所以我在自己的电脑上下载了之后复制到需要的文件夹：
cp ippicv_linux_20141027.tgz /home/zhou/opencv3.0/OpenCV/opencv-3.0.0/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b
重新运行指令：
sudo sh opencv3_0_0.sh
然后开始正常安装，并开始make，但是make到72%出现错误，graphcuts.cpp文件中许多变量没有声明，google之后发现是因为opencv3.0还不支持cuda8.0,但是有个同学已经对其进行修改。
请参考：https://github.com/opencv/opencv/pull/6510/commits/10896129b39655e19e4e7c529153cb5c2191a1db

cd  ‘/home/zhou/opencv3.0/OpenCV/opencv-3.0.0/modules/cudalegacy/src‘

sudo vi graphcuts.cpp

进行修改

然后保存并退出。

再次运行 sudo sh opencv3_0_0.sh
这次运行正常，至此opencv3.0安装成功！！！

**6）**caffe编译
下载caffe-master，解压到/home/zhou下，我重新命了个名字，caffe
然后 配置Makefile.config文件，执行指令：
cp Makefile.config.example Makefile.config

Q ?= @

make all -j16
make test -j16
make runtest -j16

make runtest –j16 时出现错误： libcudart.so.8.0: cannot open shared object file: No such file or directory

解决办法：在终端再次运行
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH
再次运行 make runtest –j16
顺利完成！！！！！！ 快夸我！！！！

编译Python和Matlab用到的caffe文件
make pycaffe -j16
make matcaffe -j16

到这里就编译完成啦！！！！可以自己用里面的例子去嗨，去浪啦！！！
