How to Install Stable Diffusion Web UI – The Complete Guide for Automatic1111

In this guide, we will explore a hassle-free approach on How to Install Stable Diffusion, a powerful web user interface. What sets this method apart is the utilization of GitHub Desktop, which provides the unique advantage of easy rollback options. By leveraging GitHub Desktop, you gain the ability to effortlessly revert installations of both the Web UI itself and any accompanying extensions. This is particularly valuable as updates to these applications can occasionally introduce issues to your existing installation.

Understanding Stable Diffusion

Stable Diffusion is a powerful webUI designed to simplify the deployment and management of web-based applications. It provides an intuitive interface for configuring settings, monitoring performance, and interacting with your applications—all without the complexities of command-line interfaces.

Before we dive into Stable Diffusion, let’s explore the broader landscape of web user interfaces. Here are four popular options:

  • Automatic1111:

    The original favorite, Automatic1111, gained prominence early on. Its straightforward design and functionality appealed to users seeking a reliable webUI.

  • ComfyUI:

    When SDXL 1.0 was released, ComfyUI emerged as a contender. Known for its up-to-date features and strong community support, it quickly became a go-to choice.

  • Invoke:

    Designed with professional studios in mind, Invoke boasts a sleek and polished UI. It’s ideal for those who demand both aesthetics and functionality.

  • Foocus:

    If simplicity is your priority, Foocus fits the bill. With a user-friendly interface reminiscent of Automatic1111, it offers ease of use without compromising on essential features.

How to Install Stable Diffusion with GitHub Desktop

The beauty of using GitHub Desktop lies in its user-friendly interface, making it accessible even to those who are not well-versed in technical matters. Through this approach, you can keep Stable Diffusion and its associated extensions consistently up to date, with the added flexibility to selectively update repositories as you see fit. As the app runs, you can monitor which repositories require updates, empowering you to manually choose which ones to update at any given time.

Unlike traditional installation methods that rely heavily on command lines, this tutorial presents a streamlined alternative that simplifies the process. By following the steps outlined here, you can effortlessly set up Stable Diffusion and maintain a robust Web UI framework, ready to accommodate your needs. So, let’s get started!

How to Install Stable Diffusion Web UI – The Complete Guide for Automatic1111

Step 2: Install Python 3.10 and Add to PATH

To ensure a seamless installation of Stable Diffusion and its crucial component, torch, it is vital to install Python 3.10.6. (I’m now using 3.10.9 because of Invoke and it works just fine on all three web UIs (Invoke, A1111, ComfyUI). Follow the steps below:

  • Visit the Python website

  • Download from Python 3.10.6 or Python 3.10.9.

    Both have been proven to work. 3.10.9 works well with Invoke.

Optional Step: Updating Xformers

Warning: Do not do this unless you need to.
Xformers, an optimization library essential for speeding up generation processes, tends to update automatically whenever you initiate A1111. However, sometimes, it doesn’t quite work as expected. I’ve experienced this issue firsthand, so I’ve laid down a step-by-step guide to help you check if you have the latest version, and if not, how to manually update it.

Verifying and Updating Your Xformers Version

  1. Locate Your A1111 Installation Folder:
    Head to your A1111 installation. In my setup, it’s labeled “stable-diffusion-webui”.
  2. Access Command Prompt in the Folder:
    • Once inside the “stable-diffusion-webui” directory, look at the top directory bar, which displays the folder breadcrumb.
    • Click on the empty space right next to the breadcrumb. This action will make the path editable.
    • Now, type “cmd” and hit Enter.
    • A command prompt will open with the directory, something like: D:\stable-diffusion-webui>
  3. Activate the Virtual Environment:
    Enter the following command: call .\venv\Scripts\activate.bat
    • List Available Xformers Versions:
    • To see all versions of Xformers, type: pip install xformers==dev
    • The highlighted version will indicate the latest one. (The last one on the list)
      The version can vary depending on when you’re going through these steps.
  4. Install the Latest Xformers Version:
    • Using the latest version you identified in the previous step,
      type: pip install xformers==[your-identified-version-number]
    • For instance, during my last check, the version was 0.0.25.dev741, so the command was:
      pip install xformers==0.0.25.dev741
    • Press Enter to start the update.

If you’ve followed along, your command prompt should look something like this:

  • Navigate to the installed file in GitHub Desktop
  • Select the repository, and then click ‘Fetch Origin.’
