wget https://developer.download.nvidia.com/compute/cuda/12.2.2/local_installers/cuda-repo-ubuntu2204-12-2-local_12.2.2-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2204-12-2-local_12.2.2-1_amd64.deb
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/3bf863cc.pub
sudo apt update
sudo apt install -y cuda-toolkit-12-2

Remember to adjust versions as needed. Set environment variables for CUDA. Add these lines to your ~/.bashrc file.

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

Apply changes with source ~/.bashrc. Verify installation with nvidia-smi and nvcc --version.

3. Python and Virtual Environments

Python is central to AI development. Use virtual environments for project isolation. This prevents dependency conflicts. Install python3-venv, which is usually pre-installed. Create a new virtual environment for your project.

mkdir my_ai_project
cd my_ai_project
python3 -m venv venv_ai
source venv_ai/bin/activate

The prompt will change, indicating activation. Now install essential AI libraries. These include TensorFlow, PyTorch, and scikit-learn.

pip install tensorflow pytorch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
pip install scikit-learn pandas numpy jupyterlab matplotlib

The PyTorch command specifies a CUDA version. Adjust cu121 to match your CUDA setup. This ensures GPU support for PyTorch. TensorFlow will automatically detect CUDA. These libraries are crucial for any “ubuntu essential dev” AI setup.

4. Docker for Containerization

Docker provides isolated, reproducible environments. It is excellent for deploying AI models. Install Docker on your Ubuntu system. Add your user to the docker group. This avoids using sudo with Docker commands.

sudo apt install -y docker.io
sudo systemctl start docker
sudo systemctl enable docker
sudo usermod -aG docker $USER
newgrp docker

Log out and back in for group changes to take effect. Test your Docker installation. Run a simple hello-world container.

docker run hello-world

This confirms Docker is working correctly. Docker is a powerful tool. It simplifies dependency management. It ensures consistent environments across machines.
