cuda nvidia driver cudnn 安装

在ubuntu16.04 上安装NVIDIA driver， cuda cudnn。显卡为GTX 750ti，Tesla K40c

1. 安装的为cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb

2.步骤：

2.1

sudo apt-get purge nvidia*

2.2

sudo dpkg -i cuda-repo-<distro>_<version>_<architecture>.deb

sudo apt-get update

sudo apt-get install cuda

2.3 POST-INSTALLATION ACTIONS（后续工作）

export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}

对于64位系统

export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64\${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

2.4 安装完成后

移动samples

cuda-install-samples-8.0.sh <dir>

重启后，检查drivers的版本：

cat /proc/driver/nvidia/version

或者

nvcc -V

nvidia-smi

2.5 对于在 ~/NVIDIA_CUDA-8.0_Samples 运行 deviceQuery 没搞明白

3. 安装成功后，各个测试结果

$ nvcc -V

4.存在的问题。

每次启动后，nvcc -V就不执行了。出现

wgb@wgb:~$ nvcc -v

The program 'nvcc' is currently not installed. You can install it by typing:

sudo apt install nvidia-cuda-toolkit

需要重新输入路径才能解决。最终解决办法，还不知！
