非常强大和模块化的 stable diffusion GUI ComfyUI

ComfyUI ======= The most powerful and modular stable diffusion GUI and backend. -----------  This ui will let you design and execute advanced stable diffusion pipelines using a graph/nodes/flowchart based interface. For some workflow examples and see what ComfyUI can do you can check out: ### [ComfyUI Examples](https://comfyanonymous.github.io/ComfyUI_examples/) ### [Installing ComfyUI](#installing) ## Features - Nodes/graph/flowchart interface to experiment and create complex Stable Diffusion workflows without needing to code anything. - Fully supports SD1.x, SD2.x, [SDXL](https://comfyanonymous.github.io/ComfyUI_examples/sdxl/), [Stable Video Diffusion](https://comfyanonymous.github.io/ComfyUI_examples/video/) and [Stable Cascade](https://comfyanonymous.github.io/ComfyUI_examples/stable_cascade/) - Asynchronous Queue system - Many optimizations: Only re-executes the parts of the workflow that changes between executions. - Command line option: ```--lowvram``` to make it work on GPUs with less than 3GB vram (enabled automatically on GPUs with low vram) - Works even if you don't have a GPU with: ```--cpu``` (slow) - Can load ckpt, safetensors and diffusers models/checkpoints. Standalone VAEs and CLIP models. - Embeddings/Textual inversion - [Loras (regular, locon and loha)](https://comfyanonymous.github.io/ComfyUI_examples/lora/) - [Hypernetworks](https://comfyanonymous.github.io/ComfyUI_examples/hypernetworks/) - Loading full workflows (with seeds) from generated PNG files. - Saving/Loading workflows as Json files. - Nodes interface can be used to create complex workflows like one for [Hires fix](https://comfyanonymous.github.io/ComfyUI_examples/2_pass_txt2img/) or much more advanced ones. - [Area Composition](https://comfyanonymous.github.io/ComfyUI_examples/area_composition/) - [Inpainting](https://comfyanonymous.github.io/ComfyUI_examples/inpaint/) with both regular and inpainting models. - [ControlNet and T2I-Adapter](https://comfyanonymous.github.io/ComfyUI_examples/controlnet/) - [Upscale Models (ESRGAN, ESRGAN variants, SwinIR, Swin2SR, etc...)](https://comfyanonymous.github.io/ComfyUI_examples/upscale_models/) - [unCLIP Models](https://comfyanonymous.github.io/ComfyUI_examples/unclip/) - [GLIGEN](https://comfyanonymous.github.io/ComfyUI_examples/gligen/) - [Model Merging](https://comfyanonymous.github.io/ComfyUI_examples/model_merging/) - [LCM models and Loras](https://comfyanonymous.github.io/ComfyUI_examples/lcm/) - [SDXL Turbo](https://comfyanonymous.github.io/ComfyUI_examples/sdturbo/) - Latent previews with [TAESD](#how-to-show-high-quality-previews) - Starts up very fast. - Works fully offline: will never download anything. - [Config file](extra_model_paths.yaml.example) to set the search paths for models. Workflow examples can be found on the [Examples page](https://comfyanonymous.github.io/ComfyUI_examples/) ## Shortcuts | Keybind | Explanation | |---------------------------|--------------------------------------------------------------------------------------------------------------------| | Ctrl + Enter | Queue up current graph for generation | | Ctrl + Shift + Enter | Queue up current graph as first for generation | | Ctrl + Z/Ctrl + Y | Undo/Redo | | Ctrl + S | Save workflow | | Ctrl + O | Load workflow | | Ctrl + A | Select all nodes | | Alt + C | Collapse/uncollapse selected nodes | | Ctrl + M | Mute/unmute selected nodes | | Ctrl + B | Bypass selected nodes (acts like the node was removed from the graph and the wires reconnected through) | | Delete/Backspace | Delete selected nodes | | Ctrl + Delete/Backspace | Delete the current graph | | Space | Move the canvas around when held and moving the cursor | | Ctrl/Shift + Click | Add clicked node to selection | | Ctrl + C/Ctrl + V | Copy and paste selected nodes (without maintaining connections to outputs of unselected nodes) | | Ctrl + C/Ctrl + Shift + V | Copy and paste selected nodes (maintaining connections from outputs of unselected nodes to inputs of pasted nodes) | | Shift + Drag | Move multiple selected nodes at the same time | | Ctrl + D | Load default graph | | Q | Toggle visibility of the queue | | H | Toggle visibility of history | | R | Refresh graph | | Double-Click LMB | Open node quick search palette | Ctrl can also be replaced with Cmd instead for macOS users # Installing ## Windows There is a portable standalone build for Windows that should work for running on Nvidia GPUs or for running on your CPU only on the [releases page](https://github.com/comfyanonymous/ComfyUI/releases). ### [Direct link to download](https://github.com/comfyanonymous/ComfyUI/releases/download/latest/ComfyUI_windows_portable_nvidia_cu121_or_cpu.7z) Simply download, extract with [7-Zip](https://7-zip.org) and run. Make sure you put your Stable Diffusion checkpoints/models (the huge ckpt/safetensors files) in: ComfyUI\models\checkpoints If you have trouble extracting it, right click the file -> properties -> unblock #### How do I share models between another UI and ComfyUI? See the [Config file](extra_model_paths.yaml.example) to set the search paths for models. In the standalone windows build you can find this file in the ComfyUI directory. Rename this file to extra_model_paths.yaml and edit it with your favorite text editor. ## Jupyter Notebook To run it on services like paperspace, kaggle or colab you can use my [Jupyter Notebook](notebooks/comfyui_colab.ipynb) ## Manual Install (Windows, Linux) Git clone this repo. Put your SD checkpoints (the huge ckpt/safetensors files) in: models/checkpoints Put your VAE in: models/vae ### AMD GPUs (Linux only) AMD users can install rocm and pytorch with pip if you don't have it already installed, this is the command to install the stable version: ```pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.7``` This is the command to install the nightly with ROCm 6.0 which might have
