sd-webui-controlnet

(WIP) WebUI extension for ControlNet and other injection-based SD controls.

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.

Install

1. Open "Extensions" tab.
2. Open "Install from URL" tab in the tab.
3. Enter https://github.com/Mikubill/sd-webui-controlnet.git to "URL for extension's git repository".
4. Press "Install" button.
5. Wait 5 seconds, and you will see the message "Installed into stable-diffusion-webui\extensions\sd-webui-controlnet. Use Installed tab to restart".
6. Go to "Installed" tab, click "Check for updates", and then click "Apply and restart UI". (The next time you can also use this method to update ControlNet.)
7. Completely restart A1111 webui including your terminal. (If you do not know what is a "terminal", you can reboot your computer: turn your computer off and turn it on again.)
8. Download models (see below).
9. After you put models in the correct folder, you may need to refresh to see the models. The refresh button is right to your "Model" dropdown.

Download Models

Right now all the 14 models of ControlNet 1.1 are in the beta test. Here is the discussion and bug report.

Download the models from ControlNet 1.1: https://huggingface.co/lllyasviel/ControlNet-v1-1/tree/main

You need to download model files ending with ".pth" .

Put models in your "stable-diffusion-webui\extensions\sd-webui-controlnet\models". Now we have already included all "yaml" files. You only need to download "pth" files.

Note: If you download models elsewhere, please make sure that yaml file names and model files names are same. Please manually rename all yaml files if you download from other sources. Otherwise, models may have unexpected behaviors. You can ignore this if you download models from official sources.

(For authors of other ControlNet model extractions or fp16 model providers: now some models like "shuffle" needs the YAML file so that we know the outputs of ControlNet should pass a global average pooling before inject to SD U-Nets. Please add yaml files with same filenames to your renaming when delivering your processed models.)

Do not right click the filenames in HuggingFace website to download. Some users right clicked those HuggingFace HTML websites and saved those HTML pages as PTH/YAML files. They are not downloading correct PTH/YAML files. Instead, please click the small download arrow “↓” icon in HuggingFace to download.

Update from ControlNet 1.0 to 1.1

If you are a previous user of ControlNet 1.0, you may:

• If you are not sure, you can back up and remove the folder "stable-diffusion-webui\extensions\sd-webui-controlnet", and then start from the step 1 in the above Install section.

• Or you can start from the step 6 in the above Install section.

Previous Models

Big Models: https://huggingface.co/lllyasviel/ControlNet/tree/main/models

Small Models: https://huggingface.co/webui/ControlNet-modules-safetensors

You can still use all previous models in the previous ControlNet 1.0. Now, the previous "depth" is now called "depth_midas", the previous "normal" is called "normal_midas", the previous "hed" is called "softedge_edge". And starting from 1.1, all line maps, edge maps, lineart maps, boundary maps will have black background and white lines.

Usage

1. Open "txt2img" or "img2img" tab, write your prompts.
2. Press "Refresh models" and select the model you want to use. (If nothing appears, try reload/restart the webui)
3. Upload your image and select preprocessor, done.

• Regarding canvas height/width: they are designed for canvas generation. If you want to upload images directly, you can safely ignore them.

T2I-Adapter Support

(From TencentARC/T2I-Adapter)

T2I-Adapter is a small network that can provide additional guidance for pre-trained text-to-image models.

To use T2I-Adapter models:

1. Download files from https://huggingface.co/TencentARC/T2I-Adapter
2. Copy corresponding config file and rename it to the same name as the model - see list below.
3. It's better to use a slightly lower strength (t) when generating images with sketch model, such as 0.6-0.8. (ref: ldm/models/diffusion/plms.py)

Note:

• This implement is experimental, result may differ from original repo.
• Some adapters may have mapping deviations (see issue lllyasviel/ControlNet#255)

Minimum Requirements

• (Windows) (NVIDIA: Ampere) 4gb - with --xformers enabled, and Low VRAM mode ticked in the UI, goes up to 768x832

Guess Mode (Non-Prompt Mode, Experimental)

Guess Mode is CFG Based ControlNet + Exponential decay in weighting.

See issue Mikubill#236 for more details.

Original introduction from controlnet:

The "guess mode" (or called non-prompt mode) will completely unleash all the power of the very powerful ControlNet encoder.

In this mode, you can just remove all prompts, and then the ControlNet encoder will recognize the content of the input control map, like depth map, edge map, scribbles, etc.

This mode is very suitable for comparing different methods to control stable diffusion because the non-prompted generating task is significantly more difficult than prompted task. In this mode, different methods' performance will be very salient.

For this mode, we recommend to use 50 steps and guidance scale between 3 and 5.

Multi-ControlNet / Joint Conditioning (Experimental)

This option allows multiple ControlNet inputs for a single generation. To enable this option, change Multi ControlNet: Max models amount (requires restart) in the settings. Note that you will need to restart the WebUI for changes to take effect.

• Guess Mode will apply to all ControlNet if any of them are enabled.

Weight and Guidance Strength/Start/End

Weight is the weight of the controlnet "influence". It's analogous to prompt attention/emphasis. E.g. (myprompt: 1.2). Technically, it's the factor by which to multiply the ControlNet outputs before merging them with original SD Unet.

Guidance Start/End is the percentage of total steps the controlnet applies (guidance strength = guidance end). It's analogous to prompt editing/shifting. E.g. [myprompt::0.8] (It applies from the beginning until 80% of total steps)

API/Script Access

This extension can accept txt2img or img2img tasks via API or external extension call. Note that you may need to enable Allow other scripts to control this extension in settings for external calls.

To use the API: start WebUI with argument --api and go to http://webui-address/docs for documents or checkout examples.

To use external call: Checkout Wiki

MacOS Support

Tested with pytorch nightly: Mikubill#143 (comment)

To use this extension with mps and normal pytorch, currently you may need to start WebUI with --no-half.

Example: Visual-ChatGPT (by API)

Quick start:

# Run WebUI in API mode
python launch.py --api --xformers

# Install/Upgrade transformers
pip install -U transformers

# Install deps
pip install langchain==0.0.101 openai 

# Run exmaple
python example/chatgpt.py

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)
