HighCWu / control-lora-v3

ControlLoRA Version 3 Pretrained Models Collection

This is a collections of control-lora-v3 weights trained on runwayml/stable-diffusion-v1-5 and stabilityai/stable-diffusion-xl-base-1.0 with different types of conditioning. You can find some example images below.

OpenPose + Segmentation

This is experimental, and it doesn't work well.

Intended uses & limitations

How to use

First clone the control-lora-v3 and cd in the directory:

git clone https://github.com/HighCWu/control-lora-v3
cd control-lora-v3

Then run the python code。

For stable diffusion, use:

# !pip install opencv-python transformers accelerate
from diffusers import UniPCMultistepScheduler
from diffusers.utils import load_image
from model import UNet2DConditionModelEx
from pipeline import StableDiffusionControlLoraV3Pipeline
import numpy as np
import torch

import cv2
from PIL import Image

# download an image
image = load_image(
    "https://hf.co/datasets/huggingface/documentation-images/resolve/main/diffusers/input_image_vermeer.png"
)
image = np.array(image)

# get canny image
image = cv2.Canny(image, 100, 200)
image = image[:, :, None]
image = np.concatenate([image, image, image], axis=2)
canny_image = Image.fromarray(image)

# load stable diffusion v1-5 and control-lora-v3 
unet: UNet2DConditionModelEx = UNet2DConditionModelEx.from_pretrained(
    "runwayml/stable-diffusion-v1-5", subfolder="unet", torch_dtype=torch.float16
)
unet = unet.add_extra_conditions(["canny"])
pipe = StableDiffusionControlLoraV3Pipeline.from_pretrained(
    "runwayml/stable-diffusion-v1-5", unet=unet, torch_dtype=torch.float16
)
# load attention processors
# pipe.load_lora_weights("HighCWu/sd-control-lora-v3-canny")
pipe.load_lora_weights("HighCWu/control-lora-v3", subfolder="sd-control-lora-v3-canny-half_skip_attn-rank16-conv_in-rank64")

# speed up diffusion process with faster scheduler and memory optimization
pipe.scheduler = UniPCMultistepScheduler.from_config(pipe.scheduler.config)
# remove following line if xformers is not installed
pipe.enable_xformers_memory_efficient_attention()

pipe.enable_model_cpu_offload()

# generate image
generator = torch.manual_seed(0)
image = pipe(
    "futuristic-looking woman", num_inference_steps=20, generator=generator, image=canny_image
).images[0]
image.show()

For stable diffusion xl, use:

# !pip install opencv-python transformers accelerate
from diffusers import AutoencoderKL
from diffusers.utils import load_image
from model import UNet2DConditionModelEx
from pipeline_sdxl import StableDiffusionXLControlLoraV3Pipeline
import numpy as np
import torch

import cv2
from PIL import Image

prompt = "aerial view, a futuristic research complex in a bright foggy jungle, hard lighting"
negative_prompt = "low quality, bad quality, sketches"

# download an image
image = load_image(
    "https://hf.co/datasets/hf-internal-testing/diffusers-images/resolve/main/sd_controlnet/hf-logo.png"
)

# initialize the models and pipeline
unet: UNet2DConditionModelEx = UNet2DConditionModelEx.from_pretrained(
    "stabilityai/stable-diffusion-xl-base-1.0", subfolder="unet", torch_dtype=torch.float16
)
unet = unet.add_extra_conditions(["canny"])
vae = AutoencoderKL.from_pretrained("madebyollin/sdxl-vae-fp16-fix", torch_dtype=torch.float16)
pipe = StableDiffusionXLControlLoraV3Pipeline.from_pretrained(
    "stabilityai/stable-diffusion-xl-base-1.0", unet=unet, vae=vae, torch_dtype=torch.float16
)
# load attention processors
# pipe.load_lora_weights("HighCWu/sdxl-control-lora-v3-canny")
pipe.load_lora_weights("HighCWu/control-lora-v3", subfolder="sdxl-control-lora-v3-canny-half_skip_attn-rank16-conv_in-rank64")
pipe.enable_model_cpu_offload()

# get canny image
image = np.array(image)
image = cv2.Canny(image, 100, 200)
image = image[:, :, None]
image = np.concatenate([image, image, image], axis=2)
canny_image = Image.fromarray(image)

# generate image
image = pipe(
    prompt, image=canny_image
).images[0]
image.show()
