本篇概览
- 自己有一台2015年的联想笔记本,显卡是GTX950M,已安装ubuntu 16.04 LTS桌面版,为了使用其GPU完成deeplearning4j的训练工作,自己动手安装了CUDA和cuDNN,在此将整个过程记录下来,以备将来参考,整个安装过程分为以下几步:
- 准备工作
- 安装Nvidia驱动
- 安装CUDA
- 安装cuDNN
特别问题说明
-
按照一般步骤,在安装完Nvidia显卡驱动后,会提示对应的CUDA版本,接下来按照提示的版本安装CUDA,例如我这里提示的是11.2,正常情况下,我应该安装11.2版本的CUDA
-
但是我选择9.1版本就行安装,因为之前的开发中发现deeplearning4j使用了11.2的SDK后,启动应用会有ClassNotFound的错误,此问题至今未修复(惭愧,欣宸水平如此之低…),因此,我在Nvidia驱动提示11.2版本的情况下,依然安装了9.1版本,后来在此环境运行deeplearning4j应用一切正常
-
如果您没有我这类问题,完全可以按照驱动指定的版本来安装CUDA,具体的操作步骤稍后会详细说到;
准备工作
-
接下来的操作,除了在网页下载,其余都是ssh远程连接到ubuntu机器操作的,ssh登录的帐号为普通帐号,并非root
-
如果已有驱动,请先删除:
sudo apt-get remove --purge nvidia*
- 禁用nouveau驱动(很重要),用vi打开文件/etc/modprobe.d/blacklist.conf,在尾部增加以下内容,然后保存退出:
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
- 关闭nouveau:
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf
- 更新initramfs:
update-initramfs -u
-
执行reboot重启电脑
-
重启后,执行以下命令,应该不会有任何输出,证明nouveau已经禁用:
lsmod|grep nouveau
- 获取Kernel source:
sudo apt-get install linux-source
- 安装过程中显示信息如下图:
- 根据上图红框中的信息,可知内核版本号为,于是执行以下命令:
sudo apt-get install linux-headers-4.4.0-210-generic
下载和安装Nvidia驱动
- 访问Nvidia网站,地址https://www.nvidia.cn/Download/index.aspx?lang=cn,然后选择对应的显卡和操作系统,我的选择如下图所示:
- 点击上图搜索按钮后,进入下图页面,点击下载:
-
下载得到的文件名为NVIDIA-Linux-x86_64-460.84.run
-
关闭图形页面:
sudo service lightdm stop
- 给驱动文件增加可执行权限:
sudo chmod a+x NVIDIA-Linux-x86_64-460.84.run
- 开始安装:
sudo ./NVIDIA-Linux-x86_64-460.84.run -no-x-check -no-nouveau-check -no-opengl-files
- 遇到下图,选择红框:
-
遇到下图,直接回车:
-
恢复图形页面:
sudo service lightdm start
- 执行命令nvidia-smi,如果驱动安装成功,会显示以下内容:
will@lenovo:~/temp/202106/20$ nvidia-smi

- 从上述内容可见CUDA Version: 11.2表示该驱动对应的CUDA版本应该是11.2,正如前面所说,我这边遇到了问题,因此接下来会安装9.1版本,但是您可以选择安装11.2
安装CUDA
- 浏览器访问https://developer.nvidia.com/cuda-toolkit-archive,点击红框中的链接:
- 如下图,下载Linux版本:
- 继续选择x86_64:
- 选择具体的Linux版本及其版本号:
- 要下载的东西不少,一个安装程序和三个补丁:
- 上述四个文件的下载地址整理如下:
https://developer.download.nvidia.cn/compute/cuda/9.1/secure/Prod/local_installers/cuda_9.1.85_387.26_linux.run?P0Ntu_6NLtuuEMm6fJRk1W5vl4KM7oaT1oFW870zKJ-zDw2ckKntFLOE6klRJfw2CmTa8z3Q390_6urlgc6LqjoqlIFW9gvfvDCusnINYplLaw1u8lRY8R4oVNtpNzaXU4BQcHjvdb6c6rjq20dktCcRd4640woXt1yHmD95v1Du7wdBBXq2eOY

-
下载完毕后,执行命令chmod a+x *.run为上述四个文件增加可执行权限
-
安装CUDA:
sudo sh cuda_9.1.85_387.26_linux.run
- 遇到license时,像是用vi工具那样,输入":",再输入"q"回车,就能跳过license阅读,执行真正的安装操作了:
- 接下来是一系列提问,每一个提问的回答如下图,千万注意红框中的问题一定要选择n:
- 安装完成后输出以下内容:
Installing the CUDA Toolkit in /usr/local/cuda-9.1 ...
Missing recommended library: libGLU.so
Missing recommended library: libX11.so
Missing recommended library: libXi.so
Missing recommended library: libXmu.so
Missing recommended library: libGL.so
Installing the CUDA Samples in /home/will ...
Copying samples to /home/will/NVIDIA_CUDA-9.1_Samples now...
Finished copying samples.
===========
= Summary =
===========
Driver: Not Selected
Toolkit: Installed in /usr/local/cuda-9.1
Samples: Installed in /home/will, but missing recommended libraries
Please make sure that
- PATH includes /usr/local/cuda-9.1/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-9.1/lib64, or, add /usr/local/cuda-9.1/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-9.1/bin
Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-9.1/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 384.00 is required for CUDA 9.1 functionality to work.
To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
sudo <CudaInstaller>.run -silent -driver
Logfile is /tmp/cuda_install_13425.log
- 打开文件~/.bashrc,在尾部增加以下两行(LD_LIBRARY_PATH如果已经存在,请参考PATH的写法改成追加):
export PATH=/usr/local/cuda-9.1/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-9.1/lib64
-
执行命令source ~/.bashrc使配置生效
-
执行命令su -切换到root帐号,执行以下命令(不要用sudo,而是切到root帐号):
sudo echo "/usr/local/cuda-9.1/lib64" >> /etc/ld.so.conf
- 再以root身份执行以下命令:
ldconfig
-
执行命令exit退出root身份,现在又是普通帐号的身份了
-
执行命令nvcc -V检查CUDA版本,注意参数V是大写:
will@lenovo:~$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver

Cuda compilation tools, release 9.1, V9.1.85
- 安装第一个补丁:
sudo sh cuda_9.1.85.1_linux.run
- 安装第二个补丁:
sudo sh cuda_9.1.85_387.26_linux.run
- 安装第三个补丁:
sudo sh cuda_9.1.85_387.26_linux.run
安装cuDNN
- 按提示登录,如果没有帐号请注册一个,登录后进入下载页面,需要点击下图红框位置才有能见到老版本:
- 选择与CUDA匹配的版本:
- 下载后解压,得到文件夹cuda,然后执行以下命令:
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*
- 执行检查确认的命令cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2,如果安装顺利会有以下输出:
#define CUDNN_MAJOR 7
#define CUDNN_MINOR 1
#define CUDNN_PATCHLEVEL 3
--
#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)
#include "driver_types.h"
- 至此,Ubuntu16安装CUDA(9.1)和cuDNN已经完成了,希望能给您一些参考。
我是欣宸,期待与您一同畅游Java世界…
