深度学习主机环境配置2---显卡配置：ubuntu-16.04.2-desktop-amd64.iso + GTX1070TI

1、ubuntu-16.04.2-desktop-amd64.iso + GTX1070TI下载对应的驱动

cuda官网：https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1604&target_type=runfilelocal

cuda_9.1.85_387.26_linux: https://developer.nvidia.com/compute/cuda/9.1/Prod/local_installers/cuda_9.1.85_387.26_linux

（或者：https://developer.nvidia.com/cuda-toolkit-archive）

2、禁止集成显卡nouveau驱动

$sudo gedit /etc/modprobe.d/blacklist.conf

然后在文本最后添加：（禁用nouveau第三方驱动，之后也不需要改回来）

blacklist
nouveau

options
nouveau modeset=0

sudo
update-initramfs -u

3、重启后，执行：

lsmod
| grep nouveau

。如果没有屏幕输出，说明禁用nouveau成功

4、禁用X-Window服务

sudo
service lightdm stop

5、按

Ctrl-Alt+F1

进入命令行界面，输入用户名root和密码登录

6、执行（如果是桌面版本，为了兼容性不黑屏，千万不要安装OpenGL）

sudo
chmod +x cuda_9.1.85_387.26_linux.run

sudo
./cuda_9.1.85_387.26_linux.run

7、配置环境变量：

按照图片指示配置环境变量

vim ./.bashrc

最后一行添加:export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-9.0/lib64

bash

8 测试：

nvidia-smi

cat
/proc/driver/nvidia/version

NVRM
version: NVIDIA UNIX x86_64 Kernel Module  384.81  Sat Sep  2 02:43:11 PDT 2017

GCC version:  gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 

#编译并测试设备
deviceQuery：cd
/usr/local/cuda-9.0/samples/1_Utilities/deviceQuery

sudo
make

./deviceQuery

cuDNN安装：

解压缩cuDNN软件包。

$ tar -xzvf cudnn-9.0-linux-x64-v7.tgz

将以下文件复制到CUDA Toolkit目录中。

$ 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 /usr/local/cuda/lib64/libcudnn*

9、启动桌面：

sudo
service lightdm start

（注意：由于本人是用的GTX1070TI，是2017年下半年出的，所以cuda8支持支持并不友好，所以选择最新的cuda9.1，

且经过多次测试，ubuntu-16.04.2-desktop-amd64.iso支持GTX1070TI较好，故选择，具体情况因人而异）

Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81?

(y)es/(n)o/(q)uit: y

Do you want to install the OpenGL libraries?

(y)es/(n)o/(q)uit [ default is yes ]: n

Do you want to run nvidia-xconfig?

This will update the system X configuration file so that the NVIDIA X driver

is used. The pre-existing X configuration file will be backed up.

This option should not be used on systems that require a custom

X configuration, such as systems with multiple GPU vendors.

===========

Driver:   Installed

Toolkit:  Installed in /usr/local/cuda-9.0

Samples:  Installed in /root, but missing recommended libraries

Please make sure that

 -   PATH includes /usr/local/cuda-9.0/bin

 -   LD_LIBRARY_PATH includes /usr/local/cuda-9.0/lib64, or, add /usr/local/cuda-9.0/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-9.0/bin

To uninstall the NVIDIA Driver, run nvidia-uninstall
