KerasCV Stable Diffusion in Diffusers 🧨🤗
DreamBooth model for the puggieace concept trained by nielsgl on the nielsgl/dreambooth-ace dataset.
It can be used by modifying the instance_prompt: a photo of puggieace.
The examples are from 2 different Keras CV models (StableDiffusion and StableDiffusionV2, corresponding to Stable Diffusion V1.4 and V2.1, respectively) trained on the same dataset (nielsgl/dreambooth-ace).
Description
The Stable Diffusion V2 pipeline contained in the corresponding repository (nielsgl/dreambooth-keras-pug-ace-sd2.1) was created using a modified version of this Space for StableDiffusionV2 from KerasCV. The purpose is to convert the KerasCV Stable Diffusion weights in a way that is compatible with Diffusers. This allows users to fine-tune using KerasCV and use the fine-tuned weights in Diffusers taking advantage of its nifty features (like schedulers, fast attention, etc.).
This model was created as part of the Keras DreamBooth Sprint 🔥. Visit the organisation page for instructions on how to take part!

Usage with Stable Diffusion V1.4
from huggingface_hub import from_pretrained_keras
import keras_cv
import matplotlib.pyplot as plt
model = keras_cv.models.StableDiffusion(img_width=512, img_height=512, jit_compile=True)
model._diffusion_model = from_pretrained_keras("nielsgl/dreambooth-pug-ace")
model._text_encoder = from_pretrained_keras("nielsgl/dreambooth-pug-ace-text-encoder")
images = model.text_to_image("a photo of puggieace dog on the beach", batch_size=3)
plt.imshow(image[0])
Usage with Stable Diffusion V2.1
from diffusers import StableDiffusionPipeline
pipeline = StableDiffusionPipeline.from_pretrained('nielsgl/dreambooth-keras-pug-ace-sd2.1')
image = pipeline().images[0]
image
