Steps

1. Update Your System

Update and upgrade your system packages:

sudo apt update && sudo apt upgrade

2. Install the NVIDIA Driver

Identify and install the recommended NVIDIA driver for your GPU:

sudo ubuntu-drivers devices
sudo apt install nvidia-driver-<version>  # Replace <version> with your recommended driver

Reboot your machine:

sudo reboot

Verify NVIDIA Driver Installation

To verify that the NVIDIA driver is installed correctly, run the following command:

nvidia-smi

You should see an output similar to the following, which indicates that the driver is installed and the GPU is recognized:

3. Install CUDA Toolkit

1. Download and install the CUDA repository package:

   wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
   sudo dpkg -i cuda-keyring_1.1-1_all.deb
   sudo apt-get update
   sudo apt-get install -y cuda

4. Set Up the Environment

Update your environment variables by adding the following lines to your .bashrc:

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-12.2/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Reload the .bashrc file:

source ~/.bashrc

Reboot your machine:

sudo reboot

5. Verify Installation

After installation, check if CUDA was installed correctly:

nvcc -V
