Anime art enthusiasts and digital creators, rejoice! The new Stable Diffusion Reference Only framework allows you to transform your anime character line art into vibrant color fan art effortlessly. Whether you are an aspiring artist or a seasoned professional, this guide will help you navigate through the process of using this powerful tool.

Understanding the Framework

Imagine a painting workshop where you bring in your black and white sketches and a talented assistant (the Stable Diffusion model) colors them in based on your suggestions of colors. That’s how the Stable Diffusion Reference Only framework operates; it takes your line art and reference images, and fills them with colors that you want, bringing your characters to life.

Getting Started

Here’s a step-by-step guide to help you use the framework:

• Create a Virtual Environment:
  • Install Miniconda to manage packages and environments.
  • Create a new environment with:

    conda create -n stable_diffusion_reference_only python=3.10
    conda activate stable_diffusion_reference_only

• Install Necessary Packages:
  • Make sure your torch environment is set up correctly. You can install the necessary packages using:

    conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia
    pip install diffusers==0.21.0
    pip install git+https://github.com/aihao2000/stable-diffusion-reference-only.git
    pip install git+https://github.com/aihao2000/anime-segmentation.git

• Run the Application:
  • Clone the repository and navigate into it:

    git clone git@github.com:aihao2000/stable-diffusion-reference-only.git
    cd stable-diffusion-reference-only
    pip install -r requirements.txt
    python3 app.py

  • Upload your character reference images and line art as prompted by the application.
  • Follow the on-screen instructions to color and enhance your artwork.

Using the Web UI for Secondary Creation

The web interface allows you to upload reference images and perform tasks like style transfer or automatic coloring directly:

• Upload a reference image with a desired color scheme.
• Upload the line art of your character.
• You can enhance your results using character segmentation to clear unwanted backgrounds.
• Click on inference to generate your final artwork!

Troubleshooting Tips

As with any application, challenges may arise. Here are some common issues and how to troubleshoot them:

• **Problem:** `Environment not found` error during activation.
  Solution: Ensure you spelled the environment name correctly when creating and activating.
• **Problem:** Installed packages are not recognized during runtime.
  Solution: Check that all installations completed successfully and retry.
• **Problem:** The application does not load images correctly.
  Solution: Verify that image formats are supported (.png, .jpg).
