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.

Technical requirements

If you have Diffusers package running in your computer, you should be able to execute all code in this chapter as well as the code used to load LoRA with Diffusers.

Diffusers use PEFT (Parameter-Efficient Fine-Tuning) [10] to manage the LoRA loading and offloading. PEFT is a library developed by Hugging Face that provides parameter-efficient ways to adapt large pre-trained models for specific downstream applications. The key idea behind PEFT is to fine-tune only a small fraction of a model’s parameters instead of fine-tuning all of them, resulting in significant savings in terms of computation and memory usage. This makes it possible to fine-tune very large models even on consumer hardware with limited resources. Turn to Chapter 21 for more about LoRA.

We will need to install the PEFT package to enable Diffusers’ PEFT LoRA loading:

pip install PEFT

You can also refer to Chapter 2, if you encounter other execution errors from the code...
