sd-webui-controlnet

(WIP) WebUI extension for ControlNet

This extension is for AUTOMATIC1111's Stable Diffusion web UI, allows the Web UI to add ControlNet to the original Stable Diffusion model to generate images. The addition is on-the-fly, the merging is not required.

ControlNet is a neural network structure to control diffusion models by adding extra conditions.

Limits

• Dragging large file on the Web UI may freeze the entire page. It is better to use the upload file option instead.
• Just like WebUI's hijack, we used some interpolate to accept arbitrary size configure (see scripts/cldm.py)
• Processor thresholds are set in scripts/processor.py. Change it if needed.
• Transfer control (for full model) is disabled by default. This option is experimental and may change in the future.

Install

Some users may need to install the cv2 library before using it: pip install opencv-python

Install prettytable if you want to use img2seg preprocessor: pip install prettytable

1. Open "Extensions" tab.
2. Open "Install from URL" tab in the tab.
3. Enter URL of this repo to "URL for extension's git repository".
4. Press "Install" button.
5. Reload/Restart Web UI.

Usage

1. Put the ControlNet models (.pt, .pth, .ckpt or .safetensors) inside the sd-webui-controlnet/models folder.
2. Open "txt2img" or "img2img" tab, write your prompts.
3. Press "Refresh models" and select the model you want to use. (If nothing appears, try reload/restart the webui)
4. Upload your image and select preprocessor, done.

Currently it supports both full models and trimmed models. Use extract_controlnet.py to extract controlnet from original .pth file.

Extraction

Two methods can be used to reduce the model's filesize:

1. Directly extract controlnet from original .pth file using extract_controlnet.py.

2. Transfer control from original checkpoint by making difference using extract_controlnet_diff.py.

All type of models can be correctly recognized and loaded. The results of different extraction methods are discussed in lllyasviel/ControlNet#12 and Mikubill#73.
