sudo apt update

# 查看可选驱动

# 选择合适驱动安装
sudo apt install nvidia-driver-xxx

# 重启
sudo reboot

# 验证是否安装成功

nvidia-smi

二、Cuda安装(以Cuda10.1为例)

# 官网下载Cuda(建议下载.run(local))

https://developer.nvidia.com/cuda-10.1-download-archive-base

## 安装
sudo sh cuda_10.1.105_418.39_linux.run

## 后处理
vim ~/.bashrc # 添加以下三行内容

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.1/lib64
export PATH=$PATH:/usr/local/cuda-10.1/bin
export CUDA_HOME=$CUDA_HOME:/usr/local/cuda-10.1

source ~/.bashrc

## 查看是否安装成功
