  --eta ETA             eta
  --tokenizer TOKENIZER
                        tokenizer
  --prompt PROMPT       prompt
  --init-image INIT_IMAGE
                        path to initial image
  --strength STRENGTH   how strong the initial image should be noised [0.0, 1.0]
  --mask MASK           mask of the region to inpaint on the initial image
  --output OUTPUT       output image name

Examples

Example Text-To-Image

python stable_diffusion.py --prompt "Street-art painting of Emilia Clarke in style of Banksy, photorealism"

Example Image-To-Image

python stable_diffusion.py --prompt "Photo of Emilia Clarke with a bright red hair" --init-image ./data/input.png --strength 0.5

Example Inapinting

python stable_diffusion.py --prompt "Photo of Emilia Clarke with a bright red hair" --init-image ./data/input.png --mask ./data/mask.png --strength 0.5

Example web demo

streamlit run demo_web.py
