**# Add Library**

```sh
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
```

**# Install nvidia-container-runtime**

```powershell
sudo apt-get install nvidia-container-runtime
systemctl restart docker
```

**#Verify if the installation was successful.**

```powershell
sudo docker run --gpus all --rm nvidia/cuda:12.0.1-base-ubuntu22.04 nvidia-smi
