安装cuda-8.0

下载安装文件

CUDA下载地址

如果找不到对应的版本，可以前往历史发行版本中浏览，地址如下：CUDA历史发行版

准备安装文件

把cuda_8.0.61_375.26_linux.run安装文件移动至当前用户根目录下

开始安装

sudo ~/cuda_8.0.61_375.26_linux.run

在安装界面中，可参照下面的描述进行选择

Do you accept the previously read EULA?accept/decline/quit: acceptInstall NVIDIA Accelerated Graphics Driver for Linux-x86_64 375.26?(y)es/(n)o/(q)uit: nInstall the CUDA 8.0 Toolkit?(y)es/(n)o/(q)uit: yEnter Toolkit Location [ default is /usr/local/cuda-8.0 ]:Do you want to install a symbolic link at /usr/local/cuda?(y)es/(n)o/(q)uit: nInstall the CUDA 8.0 Samples?(y)es/(n)o/(q)uit: n

添加环境变量

安装结束后，在管理员用户根目录下，找到.bashrc文件并打开，在最后添加下面三行文本，保存退出即可

# added by cuda_8.0 installerexport PATH="/usr/local/cuda-8.0/bin:$PATH"export LD_LIBRARY_PATH="/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH"

检测cuda是否安装成功

检测方案A：重启终端后，执行nvcc -V，若显示以下信息，则安装cuda成功

nvcc: NVIDIA (R) Cuda compiler driverCopyright (c) 2005-2016 NVIDIA CorporationBuilt on Tue_Jan_10_13:22:03_CST_2017Cuda compilation tools, release 8.0, V8.0.61

检测方案B：依次输入以下命令，测试cuda的执行结果

cd /usr/local/cuda-8.0/samples/1_Utilities/deviceQuerysudo make./deviceQuery

示例显示信息如下

若最后显示Result = PASS，表明cuda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
