T2I Adapter - Sketch

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 sketches for the stable diffusion 1.5 checkpoint.

Example

1. Dependencies

pip install diffusers transformers controlnet_aux

2. Run code:

import torch
from PIL import Image
from controlnet_aux import PidiNetDetector

from diffusers import (
    T2IAdapter,
    StableDiffusionAdapterPipeline
)

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

processor = PidiNetDetector.from_pretrained('lllyasviel/Annotators')

sketch_image = processor(image)

sketch_image.save('./images/sketch.png')

adapter = T2IAdapter.from_pretrained("TencentARC/t2iadapter_zoedepth_sd15v1", torch_dtype=torch.float16)
pipe = StableDiffusionAdapterPipeline.from_pretrained(
    "runwayml/stable-diffusion-v1-5", adapter=adapter, safety_checker=None, torch_dtype=torch.float16, variant="fp16"
)

pipe.to('cuda')

generator = torch.Generator().manual_seed(0)

sketch_image_out = pipe(prompt="royal chamber with fancy bed", image=sketch_image, generator=generator).images[0]

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