Ubuntu18.04查看显卡信息并安装NVDIA显卡驱动driver + Cuda + Cudnn

ubuntu18.04查看显卡

环境搭建01——Ubuntu如何查看显卡信息及安装NVDIA显卡驱动

原来的贴子有点老了,这里更新一下,算是一个快速安装的笔记吧!
https://blog.csdn.net/tanmx219/article/details/86553485

如何在Python中查看cuda版本

如果已经安装pytorch+cuda的话,在python中可以通过下面的命令查看torch

import torch
print(torch.version.cuda)
  • 1
  • 2

如果是在命令行下面的话,可以使用下面的指令检查

$ nvidia-smi
  • 1

下面从头开始讲

1.查看显卡型号

输入如下命令:

lshw -c video
  • 1

会显示以下信息

WARNING: you should run this program as super-user.
  *-display

2.查找你的显卡的驱动

使用这个命令查看你可以使用的驱动:

ubuntu-drivers devices
  • 1

显示结果如下,

matth32@matth32-Thurley:~/下载$ ubuntu-drivers devices

NVDIA driver search page搜索显卡需要的驱动型号并下载(如图)。

3. 安装显卡的驱动

特别说明:如果你后面还要装cuda,那么这一步就不是必须的,因为cuda安装包里是有驱动的。我原来没太注意,总是会多走这一步。不过,不论你是用这里安装driver,还是采用cuda中的driver,后面那个Nouveau都必须卸载掉,不然总会有些莫名其妙的问题。

选择推荐的那个驱动程序,
nvidia-driver-440 - distro non-free recommended
下载完后安装

 sudo sh NVIDIA-Linux-x86_64-440.100.run

附1:如何卸载Nouveau.

How to remove Nouveau kernel driver (fix Nvidia install error)

这是因为,在安装前,Nouveau可能已经启动,所以无法安装Nvidia成功。

#---open a terminal---
sudo apt-get remove nvidia*
sudo apt autoremove
sudo apt-get install dkms build-essential linux-headers-generic
 
sudo vim /etc/modprobe.d/blacklist.conf
#---save the following info into file blacklist.conf---
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
#---end of the info saved----
 
#---go back to the terminal---
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf
sudo update-initramfs -u
reboot

附2:安装过程中碰到的问题

Would you like to register the kernel module sources with DKMS? This will    
  allow DKMS to automatically build a new module, if you install a different   
  kernel later.

  but the current compiler version is cc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0.  

  This may lead to subtle problems; if you are not certain whether the         
  mismatched compiler will be compatible with your kernel, you may wish to     
  abort installation, set the CC environment variable to the name of the       
  compiler used to compile your kernel, and restart installation.

                Ignore CC version check     Abort installation         

----> select ignore

 WARNING: Ignoring CC version mismatch:

 An incomplete installation of libglvnd was found. All of the essential

  any existing libglvnd libraries.

Would you like to run the nvidia-xconfig utility to automatically update
  your X configuration file so that the NVIDIA X driver will be used when you
  restart X?  Any pre-existing X configuration file will be backed up.

4. 驱动安装后的检查

查看NVIDIA版本检验是否安装完成

$ nvidia-smi

在这里插入图片描述

环境搭建02——Ubuntu安装cuda和cudnn

查看安装的nvidia驱动版本号

如果你前面没有安装过驱动的话,这里直接路过即可。
如果你已经安装驱动的话,就要选和驱动一样的cuda。否则cuda会卸载掉驱动重新安装,至于卸载是否彻底我没仔细对比过。

可以看到版本是10.2.

选择安装的CUDA版本并下载

如果前面没有安装驱动,那么从这里开始,cuda会帮你安装上驱动,并同时安装好开发工具体(cudnn还是要后面安装)。

下载地址
英伟达官方的cuda和驱动的对应

找到DOWNLOAD-》LEGACY RELEASES类似的按钮,最后找到所需要的版本

10.2的cuda地址

安装cuda

采用官网提供的安装方式

Base Installer
Installation Instructions:

wget http://developer.download.nvidia.com/compute/cuda/10.2/Prod/local_installers/cuda_10.2.89_440.33.01_linux.run
sudo sh cuda_10.2.89_440.33.01_linux.run
  • 1
  • 2

网络不好的话会有点慢,2G多。当然也可用工具下载完后再安装。

安装时会问你要不要接受什么之类的,输入accept回车然后再直接选回车安装。

一般情况下,如果安装成功,会给出下面这样的提示性字样

===========
= Summary =
===========

Driver:   Installed
Toolkit:  Installed in /usr/local/cuda-10.2/
Samples:  Installed in /home/matthew/, but missing recommended libraries

Please make sure that
 -   PATH includes /usr/local/cuda-10.2/bin
 -   LD_LIBRARY_PATH includes /usr/local/cuda-10.2/lib64, or, add /usr/local/cuda-10.2/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-10.2/bin
To uninstall the NVIDIA Driver, run nvidia-uninstall

Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-10.2/doc/pdf for detailed information on setting up CUDA.

如果安装不成功,大多是是因为图形界面启用了drm什么之类的,用下面的办法切换到text console模式,然后再使用安装命令

sudo sh cuda_10.2.89_440.33.01_linux.run

当然,如果你是第一次使用字符界面,最好先设置密码,免得出现无法登陆的情况,

sudo passwd root

然后再使用下面的办法在字符界面安装。安装完后返回图形界面即可。

安装时报错的情况 --切换到字符界面

报错 ERROR: An NVIDIA kernel module ‘nvidia-drm’ appears to already be loaded in your kernel.

关闭用户图形界面

sudo systemctl set-default multi-user.target
sudo reboot

开启用户图形界面

sudo systemctl set-default graphical.target
sudo reboot

一般来说,切换到字符界面下后,安装就没有问题,如果切换到图形界面有困难,可以考虑下面的办法

(1)edit  /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="text"
GRUB_TERMINAL=console

(2)After saving changes you need to run:
sudo update-grub
sudo systemctl enable multi-user.target --force
sudo systemctl set-default multi-user.target

(3)Undoing text-mode
sudo systemctl enable graphical.target --force
sudo systemctl set-default graphical.target

安装后配置Cuda环境变量

在text console模式下安装成功后,会有一段提示,我们按提示配置即可,这里我们按照网上大多数人的做法配置一下,

sudo gedit ~/.bashrc
在 ~/.bashrc 的最后添加 (网上共看到三种添加内容):
第一种

export PATH=/usr/local/cuda-10.2/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.2.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
  • 1
  • 2

第二种

export PATH=/usr/local/cuda-10.2/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda10.2/lib64
  • 1
  • 2

第三种(* $PATH表示添加到PATH)

export PATH=/usr/local/cuda-10.2/bin:$PATH  
export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64:$LD_LIBRARY_PATH
export CUDA_HOME=/usr/local/cuda
  • 1
  • 2
  • 3

配置完环境变量之后,一定要更新一下,否则不能立即生效。也可以通过重启电脑使得环境变量生效:
$source ~/.bashrc
或者:
$source /etc/profile

source ~/.bashrc
nvcc --version

如果显示下面的文字就说明安装成功了:

当然你也可以查看一下路径是否设置好了,

CUDNN的安装

下载cuDNN(注意RUN-LIB.DEB包和LIB包是不同的东西)
首先到官网下载cuDNN( https://developer.nvidia.com/cudnn ),注意
cuDNN Library for Windows 7
cuDNN Library for Windows 10
cuDNN Library for Linux (------->download this one<----------)
cuDNN Runtime Library for Ubuntu18.04 (Deb)
cuDNN Developer Library for Ubuntu18.04 (Deb)
cuDNN Code Samples and User Guide for Ubuntu18.04 (Deb)
cuDNN Runtime Library for Ubuntu16.04 (Deb)
cuDNN Developer Library for Ubuntu16.04 (Deb)
cuDNN Code Samples and User Guide for Ubuntu16.04 (Deb)
可以直接下载DEB的地址:https://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64/
这个LIB需要注册为开发者才能下载,而且直接下载可能速度非常慢。RUN-LIB(没有头文件,之只有链接库)注意选择对应的版本,比如我选择的是,
libcudnn7_7.6.5.32-1+cuda10.2_amd64.deb
对应
Download cuDNN v7.6.5 (November 18th, 2019), for CUDA 10.2
Library for Windows, Mac, Linux, Ubuntu and RedHat/Centos(x86_64architecture)
cuDNN Library for Windows 7
cuDNN Library for Windows 10
cuDNN Library for Linux
cuDNN Runtime Library for Ubuntu18.04 (Deb) ---> Select this package
cuDNN Developer Library for Ubuntu18.04 (Deb)
cuDNN Code Samples and User Guide for Ubuntu18.04 (Deb)
cuDNN Runtime Library for Ubuntu16.04 (Deb)
cuDNN Developer Library for Ubuntu16.04 (Deb)
cuDNN Code Samples and User Guide for Ubuntu16.04 (Deb)
DEB(RUN-LIB)下载下来后,右键“用软件安装打开”--》“安装”,然后就OK了。

我自己因为要做开发,必须有头文件cudnn.h,所以下载的是下面的这个tgz包。
对LIB(*.tgz)当然你也可以用copy的方式(这里有头文件cudnn.h等),打开包,里面的文件都是按路径放置好的了。官方给出的安装办法

  1. Navigate to your directory containing the cuDNN Tar file.

  2. Unzip the cuDNN package.

    $ tar -xzvf cudnn-10.2-linux-x64-v7.6.5.32.tgz
    
    • 1
  3. Copy the following files into the CUDA Toolkit directory, and change the file permissions.

    $ 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*
    
    • 1
    • 2
    • 3

重复说一下,主要是解压,然后执行

sudo cp cuda/include/cudnn.h /usr/local/cuda/include/
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/
  • 1
  • 2

手动拷贝还要设置一下权限

sudo chmod a+r /usr/local/cuda/include/cudnn.h 
sudo chmod a+r /usr/local/cuda/lib64/libcudnn*
  • 1
  • 2

检查查看cudnn版本

cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

如果显示下面的文字就说明安装成功了:

#define CUDNN_MAJOR 7
#define CUDNN_MINOR 6
#define CUDNN_PATCHLEVEL 5
--
#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)

#include "driver_types.h"
