Ubuntu 16.04 Deep Learning Environment Setup

0. 查看可安装驱动列表 - Update and Upgrade

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-cache search nvidia*

(Kernel Version 4.10.09)

Install Version: NVIDIA-Linux-x86_64-390.87.run

Download Nvidia Drivers: [Nvidia Link]

1. 卸载所有原驱动 - uninstall all original drivers for safety

$ sudo apt-get purge nvidia*

2. 禁用nouveau - Disabling Nouvea

• 新建-blacklist-nouveau.conf 输⼊指令:(Create New Text)

$ sudo vim /etc/modprobe.d/blacklist-nouveau.conf

• 往文件中写⼊-input :

blacklist nouveau
blacklist lbm-nouveau options
nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

禁 Ubuntu自带开源驱动nouveau，写入后 After above 重启系统 - Disabling Nouveau

$ sudo reboot 

在终端执行行命令:(Terminal)

$ lsmod | grep nouveau

查看nouveau模块是否被加载，若无输出，则执行下一步 - If no output go to the next step.

3. 安装Nvidia驱动 - Install the Drivers

Ctrl + Alt + F1-( Enter virtual consoles )进入tty1命令行界面 
Ctrl + Alt + F7-( Return back to GUI )回到桌面系统界面

禁⽤X服务 - Kill your current X server session by typing

$ sudo service lightdm stop

给驱动run文件赋予执行权限(根据版本执行 “___” check version)

$ sudo chmod a+x NVIDIA-Linux-x86_64-390.87.run
$ sudo ./NVIDIA-Linux-x86_64-390.87.run -no-opengl-files -no-x-check -no-nouveau-check

-重点-(登录界面循环问题)

-no-opengl-files 只安装驱动文件，不安装OpenGL文件 -no-x-check 安装驱动时不检查X服务 -no-nouveau-check 安装驱动时不检查nouveau模块

-安装驱动时-

“Would you like to run the nvidia-xconfig utility to automatically update your X configuration file...”
Choose No，安装完 After above 
$sudo reboot

4. Nvidia驱动安装完成 - Check Driver was successfully installed

$ nvidia-smi

5. 安装CUDA - CUDA Toolkit 9.0 Downloads

Download Installer for Linux Ubuntu 16.04 x86_64

Download CUDA: cuda_9.0.176_384.81_linux.run [CUDA Link]

Install CUDA

$ sudo ./cuda_9.0.176_384.81_linux.run --no-opengl-libs
...
accept #同意安装
n #不安装Driver，因为已安装Nvidia驱动-already installed Nvidia
y #安装CUDA Toolkit install
<Enter> #安装到默认目录
y #创建安装目录的软链接
n #不复制Samples，因为在安装目录下有/samples

A. vim 打开.bashrc 在末行加⼊以下命令 - Add following lines to .bashrc

export PATH="/usr/local/cuda/bin:$PATH"
export LD_LIBRARY_PATH=“/usr/local/cuda/ lib64:$LD_LIBRARY_PATH”

执行指令更新 .bashrc 文件 - Reload .bashrc with

$ source .bashrc

B. 安装及路径测试，查看CUDA版本 CUDA Sample Testing:

$ nvcc -V

编译并测试设备 deviceQuery:

$ cd /usr/local/cuda-9.0/samples/1_Utilities/deviceQuery
$ sudo make
$ ./deviceQuery

编译并测试带宽 bandwidthTest:

$ cd ../bandwidthTest
$ sudo make
$ ./bandwidthTest

如果两个测试的结果都是 Result = PASS CUDA 安装成功 - Install successed

 $ cd /usr/local/cuda-9.0/samples/1_Utilities/deviceQuery
 $ sudo make
 $ ./deviceQuery
 $ cd ../bandwidthTest
 $ sudo make
 $ ./bandwidthTest

6. 安装cuDNN - Download cuDNN

Download Version: cuDNN v7.1.4 (May 16, 2018), for CUDA 9.0 [cuDNN Link]

解压后的 cudnn-9.0-linux-x64-v7.1.tgz ⽂文件cuda，执行以下指令安装:-Install cudnn

$ tar -zxvf cudnn-9.0-linux-x64-v7.1.tgz
$ cd cuda $ sudo cp lib64/lib* /usr/local/cuda/lib64/
$ sudo cp include/cudnn.h /usr/local/cuda/include/

然后更新网络连接:-Updata Network Connection

$ cd /usr/local/cuda/lib64/ $ sudo chmod +r libcudnn.so.7.1.4
$ sudo ln -sf libcudnn.so.7.1.4 libcudnn.so.7
$ sudo ln -sf libcudnn.so.7 libcudnn.so $ sudo ldconfig

7. 安装Tensorflow-gpu - Install Tensorflow-gpu

 $ pip install --user tensorflow-gpu

8. 测试 - Testing

9. 常见配置问题 - Problem

登⼊界⾯死循环问题: Login loop problem

1. 进入文本界面: CTRL+ALT+F1

2. Uninstall any previous drivers:

$ sudo apt-get remove nvidia-*
$ sudo apt-get autoremove       

3. Uninstall the drivers from the .run file:

$ sudo nvidia-uninstall

4. 此时，重启 - Reboot -> login normally

5. 驱动重新安装 - Driver reinstall

卸载Cuda - uninstall Cuda:

$ cd /usr/local/cuda/bin 
$ sudo ./uninstall_cuda_7.5.pl

卸载Cudnn - uninstall Cudnn:

$ sudo rm -rf /usr/local/cuda/include/cudnn.h sudo rm -rf /usr/
$ sudo rm -rf /usr/local/cuda/lib64/libcudnn

调整屏幕分辨率: change the display resolution

添加 /etc/X11/xorg.conf 文件，将此模式保存为默认分辨率。

$ sudo gedit /etc/X11/xorg.conf

粘贴以下内容: - copy below -> paste to xorg.conf
