If you’ve ever thought about diving into the fascinating world of artificial intelligence (AI) and image generation, you’re in the right place! Today, we’re going to explore how to set up and run experiments using the Stable-Diffusion-Latent-Space-Explorer, a powerful tool for generating stunning images based on text prompts. Let’s embark on this creative journey together!

General Information

This project is authored by Alen Smajic under the guidance of Prof. Dr. Visvanathan Ramesh. It’s hosted by two esteemed institutions:

• Goethe University
• AISEL – AI Systems Engineering Lab

Setup and Installation

Step 1: Clone the Repository

First, you’ll need to clone the repository:

git clone https://github.com/alen-smajic/Stable-Diffusion-Latent-Space-Explorer

Step 2: Create a Virtual Environment

Next, create and activate a virtual environment:

python -m venv venv

Step 3: Install PyTorch with CUDA

Follow the official PyTorch installation guide to install PyTorch with CUDA support.

Step 4: Install Required Libraries

Install the diffusers and transformers libraries:

pip install diffusers[torch] transformers

Step 5: Optional – Install xFormers

For efficient attention mechanisms, you can optionally install xFormers:

pip install xformers

Tested Versions:

If you experience issues, ensure that the versions of installed packages match the following:

• torch 2.0.0
• cuda 11.8
• diffusers 0.14.0
• xformers 0.0.16

Download Model Weights

Use git-lfs to download the model weights. Commit using:

git lfs install

git clone https://huggingface.co/stability-ai/stable-diffusion-2-1

Understanding the Code with an Analogy

Let’s visualize running an experiment as if you were a chef preparing a gourmet dish. Each step in the recipe represents a line of code:

• The virtual environment is like your kitchen; it keeps the environment clean and organized, allowing you to work without disturbances.
• The models are your ingredients, which you need to gather before starting to cook. You ensure that they are fresh and in good condition.
• When you call the script run_sd_experiment.py, it’s comparable to mixing your ingredients in a pot: you heat them at the right temperature, and the combination creates something delicious!
• Finally, just as you present your completed meal on a plate, the outputs generated by your experiment are the beautiful images you display for guests to admire.

How to Run an Experiment

To run your first experiment, you’ll need to define the parameters using an experiment configuration file. Once that’s ready, execute the following command:

python run_sd_experiment.py --exp_config .configs/experiments/path_to_your_config

Experiment Results

Each run will create a results folder with unique names based on the execution time and model identifier. Within this folder, you’ll find:

• configs: A copy of your configuration file.
• images: Generated images from Stable Diffusion.
• embeddings: Latent representations of generated images.
• gifs: Generated gifs capturing the process.

Troubleshooting Tips

In case you run into obstacles, here are some helpful troubleshooting ideas:

• Ensure that all dependencies are installed correctly.
• Double-check the versions of the libraries.
• If you’re receiving path errors, verify that you’ve input the correct paths in the experiment configurations.
• Refer to the official documentation for further guidance if needed.
