下载CUDA

官网下载按照自己的实际情况进行选择，下载合适的版本。

注意这里下载的是cuda8.0的runfile（local）文件。

安装CUDA

下载完成后，解压到当前目录，切换到该目录输入：

  sh cuda_8..44_linux.run –override //_8.0.44是本文采用的版本，安装时根据实际调整。

初始化安装

初始安装是，出现很多选择的选项，直接Ctrl+C，之后的选项参考如下：

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 ]:

输入accept接受条款

输入n不安装nvidia图像驱动，之前已经安装过了

输入y安装cuda 8.0工具

回车确认cuda默认安装路径：/usr/local/cuda-8.0

输入y用sudo权限运行安装，输入密码

输入y或者n安装或者不安装指向/usr/local/cuda的符号链接

输入y安装CUDA 8.0 Samples，以便后面测试

回车确认CUDA 8.0 Samples默认安装路径。

安装过程

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 ...

===========

= 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

添加环境路径

安装完毕后，再声明一下环境变量，并将其写入到 ~/.bashrc 的尾部:

sudo gedit ~/.bashrc

尾部添加：

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}}

然后设置环境变量和动态链接库，在命令行输入：

sudo gedit /etc/profile

在打开的文件末尾加入：

export PATH=/usr/local/cuda/bin:$PATH

保存之后，创建链接文件：

sudo gedit /etc/ld.so.conf.d/cuda.conf

在打开的文件中添加如下语句：

/usr/local/cuda/lib64

然后执行：

sudo ldconfig

使链接立即生效。

测试

cd /usr/local/cuda-8.0/samples/1_Utilities/deviceQuery

make -j4

sudo ./deviceQuery

若会输出相应的显卡性能信息，表明cuda安装成功。

cuDNN安装

下载cuDNN，解压。

tar -zxvf cudnn-8.0-linux-x64-v7.tgz

得到一个cuda文件夹，进入之后会有include文件夹和lib64文件夹

执行下列命令：

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*
