I integrated BoxDiff into diffusers

[zjysteven]

Feel free to check out https://github.com/huggingface/diffusers/tree/main/examples/community#stable-diffusion-boxdiff

Example use case:

import torch
from PIL import Image, ImageDraw
from copy import deepcopy

from examples.community.pipeline_stable_diffusion_boxdiff import StableDiffusionBoxDiffPipeline

def draw_box_with_text(img, boxes, names):
    colors = ["red", "olive", "blue", "green", "orange", "brown", "cyan", "purple"]
    img_new = deepcopy(img)
    draw = ImageDraw.Draw(img_new)

    W, H = img.size
    for bid, box in enumerate(boxes):
        draw.rectangle([box[0] * W, box[1] * H, box[2] * W, box[3] * H], outline=colors[bid % len(colors)], width=4)
        draw.text((box[0] * W, box[1] * H), names[bid], fill=colors[bid % len(colors)])
    return img_new

pipe = StableDiffusionBoxDiffPipeline.from_pretrained(
    "stabilityai/stable-diffusion-2-1-base",
    torch_dtype=torch.float16,
)
pipe.to("cuda")

# example 1
prompt = "as the aurora lights up the sky, a herd of reindeer leisurely wanders on the grassy meadow, admiring the breathtaking view, a serene lake quietly reflects the magnificent display, and in the distance, a snow-capped mountain stands majestically, fantasy, 8k, highly detailed"
phrases = [
    "aurora",
    "reindeer",
    "meadow",
    "lake",
    "mountain"
]
boxes = [[1,3,512,202], [75,344,421,495], [1,327,508,507], [2,217,507,341], [1,135,509,242]]

# example 2
# prompt = "A rabbit wearing sunglasses looks very proud"
# phrases = ["rabbit", "sunglasses"]
# boxes = [[67,87,366,512], [66,130,364,262]]

boxes = [[x / 512 for x in box] for box in boxes]

images = pipe(
    prompt,
    boxdiff_phrases=phrases,
    boxdiff_boxes=boxes,
    boxdiff_kwargs={
        "attention_res": 16,
        "normalize_eot": True
    },
    num_inference_steps=50,
    guidance_scale=7.5,
    generator=torch.manual_seed(42),
    safety_checker=None
).images

draw_box_with_text(images[0], boxes, phrases).save("output.png")

Great! Thanks for your efforts! :)
