1 安装基础环境

更新依赖包

sudo apt-get update
sudo apt-get upgrade

2 安装驱动

（1）查看适合的显卡驱动

# 查看可用的驱动
sudo ubuntu-drivers devices# 返回值，推荐版本：nvidia-driver-550

（2）安装驱动

# 安装驱动nvidia-driver550
sudo apt install nvidia-driver-550# 重启
sudo shutdown -r now

（3）查看驱动

# 查看驱动
nvidia-smi# 返回值，注意查看CUDA的版本号
CUDA Version: 12.4

3 安装CUDA

选择显卡对应版本，驱动对应的大版本即可：12.4

Continue

Install

安装成功

添加环境变量

# 编辑环境变量文件
sudo vim /etc/profile# 在最后一行添加环境变量
export PATH=$PATH:/usr/local/cuda-12.4/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-12.4/lib64
export CUDA_HOME=/usr/local/cuda-12.4/# 使环境变量生效
