安装CUDA-10.0

下载安装文件

最新发行版本：下载地址
历史发行版本：下载地址

准备安装文件

在官网中找到对应系统的安装文件，如cuda_10.0.130_410.48_linux.run
移动安装文件到用户根目录下

开始安装CUDA

安装脚本

sudo chmod +x ~/cuda_10.0.130_410.48_linux.run
sudo ~/cuda_10.0.130_410.48_linux.run
# 稍后会出现很多提示信息，可以长按空格键直接跳过

安装选项

Do you accept the previously read EULA?
accept/decline/quit: accept

Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 410.48?
(y)es/(n)o/(q)uit: no

Install the CUDA 10.0 Toolkit?
(y)es/(n)o/(q)uit: yes

Enter Toolkit Location
 [ default is /usr/local/cuda-10.0 ]: 

Do you want to install a symbolic link at /usr/local/cuda?
(y)es/(n)o/(q)uit: no

Install the CUDA 10.0 Samples?
(y)es/(n)o/(q)uit: no

添加环境变量

在用户根目录下，找到.bashrc文件并打开，在最后添加下面三行文本，保存并退出

# added by cuda 10.0 installer
export PATH="/usr/local/cuda-10.0/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/cuda-10.0/lib64:$LD_LIBRARY_PATH"

检测安装结果

在终端输入此命令并执行nvcc -V，若显示以下信息，则表示安装成功

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2018 NVIDIA Corporation
Built on Sat_Aug_25_21:08:01_CDT_2018
Cuda compilation tools, release 10.0, V10.0.130

检测是否能查询显卡信息

cd /usr/local/cuda-10.0/samples/1_Utilities/deviceQuery
sudo make && ./deviceQuery

deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 10.1, CUDA Runtime Version = 10.0, NumDevs = 1
Result = PASS

若最后显示Result = PASS，表明查询显卡信息成功
最后执行sudo make clean清除垃圾文件，并重启终端
