T2I Adapter - Color

T2I Adapter is a network providing additional conditioning to stable diffusion. Each t2i checkpoint takes a different type of conditioning as input and is used with a specific base stable diffusion checkpoint.

This checkpoint provides conditioning on color palettes for the stable diffusion 1.4 checkpoint.

Example

1. Dependencies

pip install diffusers transformers

2. Run code:

from PIL import Image
import torch
from diffusers import StableDiffusionAdapterPipeline, T2IAdapter

image = Image.open('./images/color_ref.png')

color_palette = image.resize((8, 8))
color_palette = color_palette.resize((512, 512), resample=Image.Resampling.NEAREST)

color_palette.save('./images/color_palette.png')

adapter = T2IAdapter.from_pretrained("TencentARC/t2iadapter_color_sd14v1", torch_dtype=torch.float16)
pipe = StableDiffusionAdapterPipeline.from_pretrained(
    "CompVis/stable-diffusion-v1-4",
    adapter=adapter,
    torch_dtype=torch.float16,
)
pipe.to("cuda")

generator = torch.manual_seed(0)

out_image = pipe(
    "At night, glowing cubes in front of the beach",
    image=color_palette,
    generator=generator,
).images[0]

out_image.save('./images/color_out_image.png')
