# Controlnet |
|
|
|
Controlnet is an auxiliary model which augments pre-trained diffusion models with an additional conditioning. |
|
|
|
Controlnet comes with multiple auxiliary models, each which allows a different type of conditioning |
|
|
|
Controlnet's auxiliary models are trained with stable diffusion 1.5. Experimentally, the auxiliary models can be used with other diffusion models such as dreamboothed stable diffusion. |
|
|
|
The auxiliary conditioning is passed directly to the diffusers pipeline. If you want to process an image to create the auxiliary conditioning, external dependencies are required. |
|
|
|
Some of the additional conditionings can be extracted from images via additional models. We extracted these |
|
additional models from the original controlnet repo into a separate package that can be found on [github](https://github.com/patrickvonplaten/controlnet_aux.git). |

### Diffusers |
|
|
|
Install the additional controlnet models package. |
|
|
|
```sh |
|
$ pip install git+https://github.com/patrickvonplaten/controlnet_aux.git |
|
``` |
|
|
|
```py |
|
from PIL import Image |
|
from diffusers import StableDiffusionControlNetPipeline, ControlNetModel, UniPCMultistepScheduler |
|
import torch |
|
from controlnet_aux import MLSDdetector |
|
|
|
mlsd = MLSDdetector.from_pretrained('lllyasviel/ControlNet') |
|
|
|
image = Image.open('images/room.png') |
|
|
|
image = mlsd(image) |
|
|
|
controlnet = ControlNetModel.from_pretrained( |
|
"fusing/stable-diffusion-v1-5-controlnet-mlsd", torch_dtype=torch.float16 |
|
) |
|
|
|
pipe = StableDiffusionControlNetPipeline.from_pretrained( |
|
"runwayml/stable-diffusion-v1-5", controlnet=controlnet, safety_checker=None, torch_dtype=torch.float16 |
|
) |
|
|
|
pipe.scheduler = UniPCMultistepScheduler.from_config(pipe.scheduler.config) |
|
|

# Remove if you do not have xformers installed |
|
# see https://huggingface.co/docs/diffusers/v0.13.0/en/optimization/xformers#installing-xformers |
|
# for installation instructions |
|
pipe.enable_xformers_memory_efficient_attention() |
|
|
|
pipe.enable_model_cpu_offload() |
|
|
|
image = pipe("room", image, num_inference_steps=20).images[0] |
|
|
|
image.save('images/room_mlsd_out.png') |
|
``` |

### Training |
|
|
|
The hough line model was trained on 600k edge-image, caption pairs. The dataset was generated from Places2 using BLIP to generate text captions and a deep Hough transform to generate edge-images. The model was trained for 160 GPU-hours with Nvidia A100 80G using the Canny model as a base model. |
