Overview of this book

Stable Diffusion is a game-changing AI tool that enables you to create stunning images with code. The author, a seasoned Microsoft applied data scientist and contributor to the Hugging Face Diffusers library, leverages his 15+ years of experience to help you master Stable Diffusion by understanding the underlying concepts and techniques. You’ll be introduced to Stable Diffusion, grasp the theory behind diffusion models, set up your environment, and generate your first image using diffusers. You'll optimize performance, leverage custom models, and integrate community-shared resources like LoRAs, textual inversion, and ControlNet to enhance your creations. Covering techniques such as face restoration, image upscaling, and image restoration, you’ll focus on unlocking prompt limitations, scheduled prompt parsing, and weighted prompts to create a fully customized and industry-level Stable Diffusion app. This book also looks into real-world applications in medical imaging, remote sensing, and photo enhancement. Finally, you'll gain insights into extracting generation data, ensuring data persistence, and leveraging AI models like BLIP for image description extraction. By the end of this book, you'll be able to use Python to generate and edit images and leverage solutions to build Stable Diffusion apps for your business and users.

Training a model with Hugging Face’s Accelerate

Hugging Face’s Accelerate is a library that provides a high-level API over different PyTorch distributed frameworks, aiming to simplify the process of distributed and mixed-precision training. It is designed to keep changes to your training loop to a minimum and allow the same functions to work for any distributed setup. Let’s see what Accelerate can bring to the table.

Applying Hugging Face’s Accelerate

Let’s apply Accelerate to our simple but working model. Accelerate is designed to be used together with PyTorch, so we don’t need to change too much code. Here are the steps to use Accelerate to train a model:

  1. Generate the default configuration file:
    from accelerate import utils
    utils.write_basic_config()
  2. Initialize an Accelerate instance, and send the model instance and data to the device managed by Accelerate:
    from accelerate import Accelerator
    accelerator = Accelerator()
    device...
