配置环境变量

cat >> /etc/profile <<EOF
export CUDA_HOME=/usr/local/cuda
export PATH=/usr/local/cuda-12.4/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-12.4/lib64:$LD_LIBRARY_PATH
EOF

source /etc/profile

下载 nvidia-fabricmanager

ubuntu2204 这个是系统版本

【其他系统下载】其他系统需要自己修改wget下载地址

1# 通过 nvidia-smi 看版本号，Driver Version: 550.144.03 
wget https://developer.download.nvidia.cn/compute/cuda/repos/ubuntu2204/x86_64/nvidia-fabricmanager-550_550.144.03-1_amd64.deb
dpkg -i nvidia-fabricmanager-550_550.144.03-1_amd64.deb

systemctl start nvidia-fabricmanager
systemctl enable nvidia-fabricmanager
systemctl status nvidia-fabricmanager

问题排查

cat /etc/netplan/*.yaml # 中的某个文件
# 修改网卡ens21f0np0的dns
netplan set ethernets.ens21f0np0.nameservers.addresses=[223.5.5.5,114.114.114.114]
netplan apply

配置apt源
sed -i 's/archive.ubuntu.com/mirrors.tuna.tsinghua.edu.cn/g' /etc/apt/sources.list
