Install TensorFlow with CUDA on Ubuntu 24.04

This document provides a step-by-step guide to setting up a Python virtual environment and installing TensorFlow v2.18.1 with GPU support on a machine running Ubuntu 24.04 with a compatible NVIDIA GPU.

Using a virtual environment is highly recommended to isolate your project's dependencies and avoid conflicts with other Python projects on your system.

Prerequisites

To use TensorFlow with CUDA, you must have a compatible NVIDIA GPU and the correct software installed.

This guide will walk you through the process of setting up Unsloth with NVIDIA GPU support within your Windows Subsystem for Linux 2 (WSL2) environment, specifically using an Ubuntu distribution. This setup is crucial for efficiently fine-tuning and running large language models locally.

1. Install NVIDIA GPU Driver on Windows

Before you begin in WSL2, ensure your Windows host machine has the latest NVIDIA GPU drivers installed. WSL2 relies on these drivers for GPU passthrough.

• Action: Download and install the latest drivers for your NVIDIA GPU from the official NVIDIA website: https://www.nvidia.com/drivers
• Verification: After installation, it's a good idea to restart your Windows machine.

2. Install and Set Up WSL2 (Ubuntu)
