解决 Ubuntu 中N卡 Cuda 加速不可用的问题

首先访问 Nvidia 开发者官网，选择适合你的 Ubuntu 的 Cuda Toolkit 来安装：

官网

一行一行地执行网页给出的命令，不要一大块一大块的：

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2404/x86_64/cuda-ubuntu2404.pin

sudo mv cuda-ubuntu2404.pin /etc/apt/preferences.d/cuda-repository-pin-600

wget https://developer.download.nvidia.com/compute/cuda/12.8.1/local_installers/cuda-repo-ubuntu2404-12-8-local_12.8.1-570.124.06-1_amd64.deb

sudo dpkg -i cuda-repo-ubuntu2404-12-8-local_12.8.1-570.124.06-1_amd64.deb

sudo cp /var/cuda-repo-ubuntu2404-12-8-local/cuda-*-keyring.gpg /usr/share/keyrings/

sudo apt-get update

sudo apt-get -y install cuda-toolkit-12-8

接下来跟着另一份官方文档输入命令：

[文档](Installing the NVIDIA Container Toolkit​docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html)

因为我的系统版本为 Ubuntu24.10，所以用适用于 Ubuntu 的命令：

curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
  && curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
    sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

sudo apt-get update

sudo apt-get install -y nvidia-container-toolkit

然后找到下方 Configuring Docker：

输入以下命令就完成了：

sudo nvidia-ctk runtime configure --runtime=docker

sudo systemctl restart docker
