显卡驱动重装

为了确信是否显卡驱动可以正常使用

CUDA安装

系统要求

  • 支持cuda的GPU
  • ubuntu16.04等受支持的Linux版本
  • NVIDIA CUDA工具包
  • 验证是否拥有支持cuda的GPU
lspci | grep -i nvidia

如果有显示,那么你的GPU就具备了CUDA功能。

  • 验证linux版本是否支持
uname -m && cat /etc/*release

得到以下显示:

x86_64

DISTRIB_ID=Ubuntu

DISTRIB_RELEASE=16.04

DISTRIB_CODENAME=xenial

DISTRIB_DESCRIPTION="Ubuntu 16.04.5 LTS"

NAME="Ubuntu"

VERSION="16.04.5 LTS (Xenial Xerus)"

ID=ubuntu

ID_LIKE=debian

PRETTY_NAME="Ubuntu 16.04.5 LTS"

VERSION_ID="16.04"

HOME_URL="http://www.ubuntu.com/"

SUPPORT_URL="http://help.ubuntu.com/"

BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"

VERSION_CODENAME=xenial

UBUNTU_CODENAME=xenial

  • 验证gcc
gcc --version

得到结果:

gcc (Ubuntu 4.9.3-13ubuntu2) 4.9.3

  • 验证内核

CUDA驱动程序要求在安装驱动程序时安装内核运行版本的内核头文件和开发包,以及重建驱动程序时。例如,如果您的系统运行内核版本3.17.4-301,则还必须安装3.17.4-301内核头文件和开发包。

虽然Runfile安装不执行包验证,但如果当前没有安装这些包的版本,则驱动程序的RPM和Deb安装将尝试安装内核头和开发包。但是,它将安装这些软件包的最新版本,这些软件包可能与您的系统正在使用的内核版本匹配,也可能不匹配。 因此,最好在安装CUDA驱动程序之前以及更改内核版本时手动确保安装正确版本的内核头文件和开发包。

可以通过运行以下命令找到系统正在运行的内核版本:

uname -r

安装符合当前的kernel的内核头文件和开发包:

sudo apt-get install linux-headers-$(uname -r)
  • 下载验证

可以通过将

(9.2)http://developer.nvidia.com/cuda-downloads/checksums

(9.0)https://developer.download.nvidia.com/compute/cuda/9.0/Prod/docs/sidebar/md5sum.txt

上发布的MD5校验和与下载文件的校验和进行比较来验证下载。如果任一校验和不同,则下载的文件已损坏,需要再次下载。

9.0的md5校验

要计算下载文件的MD5校验和,请运行以下命令:

$ md5sum <file>

我下载的是cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64.deb,所以用到的校验码为d717d6649cbf90d32e3fd2c0c7202be0,如果你下载的是cuda_9.0.176_384.81_linux.run,那么对应的校验码是7a00187b2ce5c5e350e68882f42dd507

处理之前安装的cuda文件

之前安装的版本会对现有版本造成冲突,需要卸载

Use the following command to uninstall a Toolkit runfile installation:

$ sudo /usr/local/cuda-X.Y/bin/uninstall_cuda_X.Y.pl

Use the following command to uninstall a Driver runfile installation:

$ sudo /usr/bin/nvidia-uninstall

Use the following commands to uninstall a RPM/Deb installation:

$ sudo yum remove <package_name>                      # Redhat/CentOS
$ sudo dnf remove <package_name> # Fedora
$ sudo zypper remove <package_name> # OpenSUSE/SLES
$ sudo apt-get --purge remove <package_name> # Ubuntu

下载的deb安装过程

Installation Instructions(下载界面提供):

sudo dpkg -i cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64.deb

sudo apt-key add /var/cuda-repo-<version>/7fa2af80.pub

sudo apt-get update

sudo apt-get install cuda

官方说明提供:

  1. 安装元数据
sudo dpkg -i cuda-repo-<distro>_<version>_<architecture>.deb
  1. 安装公钥

使用本地仓库进行安装时:

$ sudo apt-key add /var/cuda-repo-<version>/7fa2af80.pub

使用网络仓库安装时:

$ sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/<distro>/<architecture>/7fa2af80.pub
  1. 更新apt存储库缓存
sudo apt-get update
  1. 安装cuda
sudo apt-get install cuda

下载的runfile的安装过程

  • 卸载已有的NVIDIA驱动(可选):sudo apt-get remove --purge nvidia*

    一些开发需要的包(可选):
sudo apt-get install build-essential
sudo apt-get install vim cmake git
sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libboost-all-dev libhdf5-serial-dev
  • 屏蔽nouveau,sudo vim /etc/modprobe.d/blacklist-nouveau.conf,加入
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
  • 禁用 nouveau 内核模块
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf
sudo update-initramfs -u

重启计算机 sudo reboot

  • 临时关闭图形界面
sudo service lightdm stop
  • 执行安装(注意参数,不安装opengl-lib)
sudo sh cuda_<version>_linux.run --override --no-opengl-lib
Do you accept the previously read EULA? (accept/decline/quit): accept
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64? ((y)es/(n)o/(q)uit): y
Install the CUDA Toolkit? ((y)es/(n)o/(q)uit): y
Enter Toolkit Location [ default is /usr/local/cuda-9.1 ]:
Do you want to install a symbolic link at /usr/local/cuda? ((y)es/(n)o/(q)uit): y
Install the CUDA Samples? ((y)es/(n)o/(q)uit): y
Enter CUDA Samples Location [ default is /home/user ]:

如果安装没有报错,重启使驱动生效。检查驱动状态: nvidia-smi

  • 修改环境变量: (可编辑 .bashrc 或 /etc/profile 文件)
$ export PATH=/usr/local/cuda-9.1/bin${PATH:+:${PATH}}
$ export LD_LIBRARY_PATH=/usr/local/cuda-9.1/lib64 ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

编译运行CUDA测试用例(自行查看官方说明)。

安装完以后的操作

The PATH variable needs to include /usr/local/cuda-9.0/bin

To add this path to the PATH variable:

$ export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}

In addition, when using the runfile installation method, the LD_LIBRARY_PATH variable needs to contain /usr/local/cuda-9.0/lib64 on a 64-bit system, or /usr/local/cuda-9.0/lib on a 32-bit system

  • To change the environment variables for 64-bit operating systems:

    $ export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64\
    ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
  • To change the environment variables for 32-bit operating systems:

    $ export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib\
    ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Note that the above paths change when using a custom install path with the runfile installation method.

验证安装

  • 验证驱动版本

When the driver is loaded, the driver version can be found by executing the command

$ cat /proc/driver/nvidia/version
  • 编译例子进行测试

The version of the CUDA Toolkit can be checked by running nvcc -V in a terminal window. The nvcc command runs the compiler driver that compiles CUDA programs. It calls the gcc compiler for C code and the NVIDIA PTX compiler for the CUDA code.

The NVIDIA CUDA Toolkit includes sample programs in source form. You should compile them by changing to ~/NVIDIA_CUDA-9.0_Samples and typing make. The resulting binaries will be placed under ~/NVIDIA_CUDA-9.0_Samples/bin.

  • 运行二进制文件

编译后,找到并运行 DEVICEQUERY 下 〜/ NVIDIA_CUDA- 9.0 _Samples

from the command line as the superuser.

Running the bandwidthTest program ensures that the system and the CUDA-capable device are able to communicate correctly.

继续安装cuDNN

Unzip the cuDNN package.

$ tar -xzvf cudnn-<>.tgz

Copy the following files into the CUDA Toolkit directory.(注意路径)

$ 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*

编译运行CUDA测试用例(自行查看官方说明)

解决问题的思路

主要问题:NVIDIA驱动装不上(或者装完图形界面出现问题)、驱动装上了但和CUDA要求的版本不匹配

  1. 谨慎使用最新版NVIDIA驱动和Ubuntu自带的附加驱动
  2. 建议使用CUDA自带的GPU驱动程序,不建议单独安装驱动程序
  3. 建议参考官方教程进行安装
  4. 旧版教程参考意义不大
  5. 建议关掉图形界面进行安装

Trouble Shootting

  1. 安装过程出现 "The driver installation is unable to locate the kernel source. ",使用uname -r查看内核版本,如果高于4.10,如4.13.0,CUDA 9.1自带驱动不支持最新Linux内核,请降级内核:

    sudo apt-get purge linux-image-4.13.0-26-generic
    sudo apt-get purge linux-headers-4.13.0-26-generic

    Update initramfs image:

    sudo update-initramfs -u

    重启,使用 uname -r 命令确保内核版本正确

  2. 如果确认内核版本没问题了,还出现(1)的问题,再尝试安装以下包:

    apt-get install linux-source
    apt-get source linux-image-$(uname -r)
    apt-get install linux-headers-$(uname -r)
