Stable Diffusion XL Inference With PyTorch Weights And More Features Like Stable Diffusion Web UI In Keras 3.x

Why do this?

While huggingface diffusers and AUTOMATIC1111 webui library is amazing, nowdays, its implementation has gotten extremely big and unfriendly for people who want to build on it. I've always wished that an implementation existed that was not only easy to learn but also easy to maintain and develop. so, I did this project. It's like building a bridge that is compatible with the resources of the active PyTorch community, but at the same time will have the multiple features of Keras/TensorFlow.

Using pip without a virtual environment

Install dependencies using the requirements.txt file:

pip install -r requirements.txt

Run

streamlit run app.py

Using the Python interface

If you installed the package, you can use it as follows:

from PIL import Image

from stable_diffusion_xl.stable_diffusion_xl import StableDiffusionXL

# load ckpt from local path
model = StableDiffusionXL(img_height=1024, img_width=1024, jit_compile=True,
                          unet_ckpt="/path/to/unet.safetensors",
                          vae_ckpt="/path/to/vae.safetensors",
                          text_encoder_ckpt="/path/to/text_encoder.safetensors",
                          text_encoder2_ckpt="/path/to/text_encoder2.safetensors")
img = model.text_to_image(
  "a cute girl.",
  num_steps=25,
  seed=123456)
Image.fromarray(img[0]).save("out.jpg")

# for Image To Image
model = StableDiffusionXL(img_height=1024, img_width=1024, jit_compile=True)
img = model.image_to_image(
  "a cute girl.",
  reference_image="/path/to/a_girl.jpg",
  reference_image_strength=0.8,
  num_steps=50,
)
Image.fromarray(img[0]).save("out.jpg")

# for Inpaint
model = StableDiffusionXL(img_height=1024, img_width=1024, jit_compile=True)
img = model.inpaint(
  "A dog with sunglasses, wearing comfy hat, looking at camera, highly detailed, ultra sharp, cinematic, 100mm lens, 8k resolution.",
  reference_image="/path/to/dog.jpg",
  inpaint_mask="/path/to/dog_mask.png",
  mask_blur_strength=5,
  unconditional_guidance_scale=8.0,
  reference_image_strength=0.9,
  num_steps=50,
)
Image.fromarray(img[0]).save("out.jpg")
