Stable Diffusion: How to Run on Your PC to Generate AI Images

AI-generated artwork is incredibly popular at the moment, but most AI image generators are cloud-based, meaning they run on servers on the internet. However, Stable Diffusion stands out because it allows you to install and use it on your own personal computer. This means you can generate as many images as you like without relying on an internet connection. If you have a Windows PC, here’s a guide on how you can install and use Stable Diffusion.

What Is Stable Diffusion? Know How to Run Stable Diffusion on Your PC to Generate AI Images.

Stable Diffusion is a machine learning model that is freely available to use. It can create images from text descriptions, make changes to existing images based on text instructions, or enhance low-quality images. This model has been trained on a vast amount of image data, allowing it to generate high-quality results similar to other advanced models like DALL-E 2 and MidJourney. It was developed by Stability AI and became publicly available on August 22, 2022.

Stable Diffusion, unlike some AI image generators, doesn’t have a clean and organized user interface at the moment. However, it has a very flexible license and, most importantly, it is completely free for you to use on your personal computer (PC or Mac). Don’t worry if you’re not familiar with using a command-line interface (CLI) for Stable Diffusion. It’s actually quite easy to set up and get started with. If you can double-click on an executable file and type in a text box, you can have Stable Diffusion running in just a few minutes.

Requirements for Running Stable Diffusion on Your PC to run Stable Diffusion on Your PC to Generate AI Images

Stable Diffusion cannot be run on your phone or most laptops. However, it can be run on an average gaming PC from 2022. Here are the specifications you need to meet for it to work properly.

If you don’t have the necessary equipment, you can try using an AI image generator available on the internet. You can even test out a demo of Stable Diffusion on a web platform.

Installation and Execution Guide for Stable Diffusion on Windows

To get started, you’ll need two software programs: Git and Miniconda3.

Installing Git:

To install Git, follow these steps:

  • Open your web browser and search for “Git download”.
  • Look for the official website of Git (git-scm.com) and click on it.
  • On the Git website, find the download section and click on the appropriate installer for your operating system (e.g., Windows, macOS, Linux).
  • Once the installer is downloaded, locate the file and double-click on it to start the installation process.
  • Follow the on-screen instructions provided by the installer. You can generally choose the default settings unless you have specific preferences.
  • After the installation is complete, you should have Git installed on your computer. You can verify this by opening the command prompt or terminal and typing “git –version”. If Git is properly installed, it will display the version number.

If you’re not a developer, you can use Git to access and download projects conveniently. In this case, you can download the Windows x64 installer from the Git website and install it on your computer.

During the installation process, you’ll come across several options. It’s best to keep them on their default settings. Pay attention to one specific option called “Adjusting Your PATH Environment”.

Installing Miniconda3

To use Stable Diffusion, you need to install Miniconda3. Stable Diffusion relies on several Python libraries, which are essentially software packages that enable your computer to perform specific tasks like image transformation or complex mathematical operations. Don’t worry if you’re not familiar with Python; just think of these libraries as tools that help Stable Diffusion work smoothly.

To utilize Stable Diffusion, you will need to install Miniconda3. Stable Diffusion depends on various Python libraries, which are like software packages that allow your computer to perform specific tasks such as manipulating images or carrying out complex mathematical operations. If you’re not familiar with Python, you can think of these libraries as tools that enable Stable Diffusion to function properly and efficiently.

How to Use Stable Diffusion

To use Stable Diffusion, it’s important to activate the ldm environment we set up. You can do this by entering “conda activate ldm” in the Minicon. Then we need to change the directory (thus the command cd) to

“C:\stable-diffusion\stable-diffusion-main” before we can generate any images. Paste cd C:\stable-diffusion\stable-diffusion-main into the command line.

NOTE: You only have to enter that command when you open Miniconda3. The ldm environment will stay active as long as you don’t close the window.

How to Make an Image with Stable Diffusion

To generate images from text prompts, we’ll use a script called “txt2img.py“. This script converts the prompts into 512×512 pixel images. Here’s an example of how to use it to ensure everything is functioning properly:

Open the command prompt or terminal and run the following command:

python scripts/txt2img.py –prompt “a close-up portrait of a cat by Pablo Picasso, with vivid and abstract art, full of colors and vibrancy” –plms –n_iter 5 –n_samples 1

This command will execute the script and generate one image based on the given prompt. The prompt specifies a close-up portrait of a cat created in the artistic style of Pablo Picasso. The resulting image should be vibrant, abstract, and filled with colourful elements. The script will run for five iterations to refine the image and generate the best possible result.

By using a specific command, you can generate five cat images that will be saved in a particular location on your computer. These images may not be exact replicas, but they will resemble the artistic style of Pablo Picasso, as mentioned in the command. To generate different images, you can modify the text within the quotation marks after “–prompt.”

python scripts/txt2img.py –prompt “YOUR, DESCRIPTIONS, GO, HERE” –plms –n_iter 5 –n_samples 1

For example, if you want to create a realistic image of a gopher wearing a wizard’s hat in a magical forest, you can use a command similar to the one provided. It’s important to be specific in your description to achieve the desired result, such as mentioning realistic details or the style of a particular artist.

python scripts/txt2img.py –prompt “a photograph of a gopher wearing a wizard hat in a forest, vivid, photorealistic, magical, fantasy, 8K UHD, photography” –plms –n_iter 5 –n_samples 1

The image generation process allows for various subjects beyond just portraits and animals; it can also produce impressive landscape images.

Experimentation is key to obtaining the best results, and it can be an enjoyable part of the process. Remember to take note or save the arguments and descriptions that give you the images you like.
