The Ultimate Guide to Installing PyTorch on a GPU Server

If you are diving into deep learning, training large language models (LLMs), or running complex AI workloads, a GPU dedicated server gives you the bare-metal performance required to maximize compute efficiency. However, to harness the full power of your hardware, you need to configure your software stack correctly.

At Fit Servers, we've put together a comprehensive guide to help developers and AI researchers set up their environments from scratch.

What You Will Learn

In this guide, we walk you through the exact steps to install and configure:

  1. System Preparation: Purging old drivers and updating Ubuntu 22.04 LTS.
  2. NVIDIA Drivers: Installing stable production drivers (v560).
  3. CUDA Toolkit & cuDNN: Setting up CUDA 12.4 for modern PyTorch builds and compiling custom kernels like FlashAttention.
  4. Environment Management: Using Miniconda to isolate your Python dependencies.
  5. PyTorch Installation: Fetching the latest CUDA-compatible wheels.
  6. Benchmarking: A custom Python script to verify your TFLOPS and ensure your GPU is fully recognized.

Why Bare-Metal?

Virtualization overhead can silently eat away at your model training times. Setting up PyTorch directly on a bare-metal GPU server ensures 100% of your compute goes toward your matrix multiplications, not hypervisor bloat.
