Ubuntu 16.04 NVIDIA 1080 安装 cuda9.0
1，安装nvidia驱动
- 没有输出信息，nouveau已经禁用
lsmod | grep nouveau
# ubuntu-drivers devices
# apt install -y nvidia-430
# reboot
2，安装cuda9.0
- CUDA Toolkit 9.0 Downloads
# wget https://developer.nvidia.com/compute/cuda/9.0/Prod/local_installers/cuda_9.0.176_384.81_linux-run
accept同意安装，Graphics Driver 选择N不安装，其它选择y安装，默认安装路径
# sudo sh cuda_9.0.176_384.81_linux-run
Do you accept the previously read EULA?
accept/decline/quit: accept
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81?
(y)es/(n)o/(q)uit: n
3，设置环境变量
vim /root/.bashrc添加
export PATH=$PATH:/usr/local/cuda-9.0/bin
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
# source /root/.bashrc
# reboot
- 安装成功
# nvcc -V

- 卸载CUDA
sudo /usr/local/cuda-9.0/bin/uninstall_cuda_9.0.pl
# nvcc -V
程序“nvcc”尚未安装。 您可以使用以下命令安装：
- 卸载nvidia驱动
nvidia-smi
# dpkg -l | grep nvidia*
# sudo apt-get purge nvidia*
# reboot
