-ComfyUI lets you design and execute advanced stable diffusion pipelines using a graph/nodes/flowchart based interface. Available on Windows, Linux, and macOS. +## Table of Contents -## Get Started +- [What's New?](#whats-new) +- [Dependencies](#dependencies) +- [Setup (Windows-Only)](#setup-windows-only) +- [Troubleshooting](#troubleshooting) +- [Examples](#examples) +- [Credits](#credits) -#### [Desktop Application](https://www.comfy.org/download) -- The easiest way to get started. -- Available on Windows & macOS. +## What's New? +* Added "CFZ Cudnn Toggle" node, it is for some of the audio models, not working with cudnn -which is enabled by default on new install method- to use it just connect it before ksampler -latent_image input or any latent input- disable cudnn, THEN after the vae decoding -which most of these problems occur- to re-enable cudnn , add it after vae-decoding, select audio_output and connect it save audio node of course enable cudnn now.This way within that workflow you are disabling cudnn when working with models that are not compatible with it, so instead of completely disabling it in comfy we can do it locally like this. +* Added an experiment of mine, "CFZ Checkpoint Loader", a very basic quantizer for models. It only works -reliably- with SDXL and variants aka noobai or illustrious etc. It only works on the unet aka main model so no clips or vae. BUT it gives around %23 to %29 less vram usage with sdxl models. The generation time slows around 5 to 10 percent at most. This is especially good for low vram folks, 6GB - 8GB it could even be helpful for 4GB I don't know. Feel free to copy- modify- improve it, and try it with nvidia gpu's as well. Of course this fork is AMD only but you can take it and try it anywhere. Just you know I am not actively working on it, and besides SDXL cannot guarantee any vram improvements let alone a working node :) NOTE: It doesn't need any special packages or hardware so it probably would work with any gpu. Again, don't ask me to add x etc. +* BOTH of these nodes are inside "cfz" folder, to use them copy them into custom_nodes, they would appear next time you open comfy, to find them searh for "cfz" you will see both nodes. +* flash-attention download error fixed, also added sage-attention fix, especially for vae out of memory errors that occurs a lot with sage-attention enabled. NOTE : this doesn't require any special packages or hardware as far as I know so it could work with everything. +* `install-n.bat` now not only installs everything needed for MIOPEN and Flash-Attention use, it also automates installing triton (only supported for python 3.10.x and 3.11.x) and flash-attention. So if you especially have 6000+ gpu , have HIP 6.2.4 and libraries if necessary, try it. But beware, there are lots of errors yet to be unsolved. So it is still not the default installed version. +* If you want to enable MIOPEN , Triton and Flash-Attention use the install-n.bat . This will install torch 2.7 , with latest nightly zluda and patch the correct files into comfyui-zluda. This features do not work very well and you are on your own if you want to try these. (---- You have to install HIP 6.2.4 - Download and extract HIP Addon inside the folder (information down below on installation section). ---) +* Florance2 is now fixed , (probably some other nodes too) you need to disable "do_sample" meaning change it from True to False, now it would work without needing to edit it's node. +* Added onnxruntime fix so that it now uses cpu-only regardless of node. So now nodes like pulid, reactor, infiniteyou etc works without problems and can now use codeformer too. +* Added a way to use any zluda you want (to use with HIP versions you want to use such as 6.1 - 6.2) After installing, close the app, run `patchzluda2.bat`. It will ask for url of the zluda build you want to use. You can choose from them here, + [lshyqqtiger's ZLUDA Fork](https://github.com/lshqqytiger/ZLUDA/releases) then you can use `patchzluda2.bat`, run it paste the link via right click (A correct link would be like this, `https://github.com/lshqqytiger/ZLUDA/releases/download/rel.d60bddbc870827566b3d2d417e00e1d2d8acc026/ZLUDA-windows-rocm6-amd64.zip`) + After pasting press enter and it would patch that zluda into comfy for you. -#### [Windows Portable Package](#installing) -- Get the latest commits and completely portable. -- Available on Windows. +* Reverted zluda version back to 3.8.4. After updating try running patchzluda and if still have problems, delete venv and re-run install.bat. +* U̶p̶d̶a̶t̶e̶d̶ Z̶L̶U̶D̶A̶ v̶e̶r̶s̶i̶o̶n̶ t̶o̶ 3̶.8̶.5̶.

This aims to use low vram and provides the very basic necessary files needed to get flux generation running. [HERE](fluxguide.md) +* Added --reserve-vram with the value of 0.9 to commandline options that run with the app on startup. Greatly helps reduce using too much memory on generations. +* Changed `start.bat` to `comfyui.bat` because there is already a windows command by that name, which + creates some problems. Also added `fix-update.bat` which solves the problem that causes not being able to + update to the latest version. -#### [Manual Install](#manual-install-windows-linux) -Supports all operating systems and GPU types (NVIDIA, AMD, Intel, Apple Silicon, Ascend). +> [!IMPORTANT] +> +> 📢 ***REGARDING KEEPING THE APP UP TO DATE*** +> +> Avoid using the update function from the manager, instead use `git pull`, which we +> are doing on every start if `start.bat` is used. (App Already Does It Every Time You Open It, If You Are Using +> `comfyui.bat`, So This Way It Is Always Up To Date With Whatever Is On My GitHub Page) +> +> Only use comfy manager to update the extensions +> (Manager -> Custom Nodes Manager -> Set Filter To Installed -> Click Check Update On The Bottom Of The Window) +> otherwise it breaks the basic installation, and in that case run `install.bat` once again. +> +> 📢 ***REGARDING RX 480-580 AND SIMILAR GPUS*** +> +> After a while we need to keep updating certain packages to keep up with the original app and certain requirements of +> some models etc. So, torch is changed over time , but this gave gpu's prior to rdna some negative performance. +> So for these gpu's please use `fixforrx580.bat` if you are having memory problems too much slowdown etc. This +> is not mandatory and it won't just make your gpu faster then before but it would be less problematic then using latest torch +> that we use with other gpu's. +> +> 📢 ***RANDOM TIPS & TRICKS REGARDING USING AMD GPU'S*** +> +> * The generation speed is slower than nvidia counterparts we all know and accept it, but most of the time the out of memory situation +> at the end with VAE decoding is worse. To overcome this use "--cpu-vae". Add it to commandline_args on comfyui.bat. +> You can now decode using your system memory (the more the memory the better) and your cpu power. This might be slower but at least it works. -## [Examples](https://comfyanonymous.github.io/ComfyUI_examples/) -See what ComfyUI can do with the [example workflows](https://comfyanonymous.github.io/ComfyUI_examples/). +## Dependencies -## Features -- Nodes/graph/flowchart interface to experiment and create complex Stable Diffusion workflows without needing to code anything. -- Image Models - - SD1.x, SD2.x, - - [SDXL](https://comfyanonymous.github.io/ComfyUI_examples/sdxl/), [SDXL Turbo](https://comfyanonymous.github.io/ComfyUI_examples/sdturbo/) - - [Stable Cascade](https://comfyanonymous.github.io/ComfyUI_examples/stable_cascade/) - - [SD3 and SD3.5](https://comfyanonymous.github.io/ComfyUI_examples/sd3/) - - Pixart Alpha and Sigma - - [AuraFlow](https://comfyanonymous.github.io/ComfyUI_examples/aura_flow/) - - [HunyuanDiT](https://comfyanonymous.github.io/ComfyUI_examples/hunyuan_dit/) - - [Flux](https://comfyanonymous.github.io/ComfyUI_examples/flux/) - - [Lumina Image 2.0](https://comfyanonymous.github.io/ComfyUI_examples/lumina2/) - - [HiDream](https://comfyanonymous.github.io/ComfyUI_examples/hidream/) -- Video Models - - [Stable Video Diffusion](https://comfyanonymous.github.io/ComfyUI_examples/video/) - - [Mochi](https://comfyanonymous.github.io/ComfyUI_examples/mochi/) - - [LTX-Video](https://comfyanonymous.github.io/ComfyUI_examples/ltxv/) - - [Hunyuan Video](https://comfyanonymous.github.io/ComfyUI_examples/hunyuan_video/) - - [Nvidia Cosmos](https://comfyanonymous.github.io/ComfyUI_examples/cosmos/) - - [Wan 2.1](https://comfyanonymous.github.io/ComfyUI_examples/wan/) -- Audio Models - - [Stable Audio](https://comfyanonymous.github.io/ComfyUI_examples/audio/) - - [ACE Step](https://comfyanonymous.github.io/ComfyUI_examples/audio/) -- 3D Models - - [Hunyuan3D 2.0](https://docs.comfy.org/tutorials/3d/hunyuan3D-2) -- Asynchronous Queue system -- Many optimizations: Only re-executes the parts of the workflow that changes between executions. -- Smart memory management: can automatically run models on GPUs with as low as 1GB vram. -- Works even if you don't have a GPU with: ```--cpu``` (slow) -- Can load ckpt, safetensors and diffusers models/checkpoints.

Launch ComfyUI by running `python main.py` - -# Running - -```python main.py``` - -### For AMD cards not officially supported by ROCm - -Try running it with this command if you have issues: - -For 6700, 6600 and maybe other RDNA2 or older: ```HSA_OVERRIDE_GFX_VERSION=10.3.0 python main.py``` - -For AMD 7600 and maybe other RDNA3 cards: ```HSA_OVERRIDE_GFX_VERSION=11.0.0 python main.py``` - -### AMD ROCm Tips - -You can enable experimental memory efficient attention on recent pytorch in ComfyUI on some AMD GPUs using this command, it should already be enabled by default on RDNA3. If this improves speed for you on latest pytorch on your GPU please report it so that I can enable it by default. - -```TORCH_ROCM_AOTRITON_ENABLE_EXPERIMENTAL=1 python main.py --use-pytorch-cross-attention``` - -You can also try setting this env variable `PYTORCH_TUNABLEOP_ENABLED=1` which might speed things up at the cost of a very slow initial run. - -# Notes - -Only parts of the graph that have an output with all the correct inputs will be executed. - -Only parts of the graph that change from each execution to the next will be executed, if you submit the same graph twice only the first will be executed. If you change the last part of the graph only the part you changed and the part that depends on it will be executed. - -Dragging a generated png on the webpage or loading one will give you the full workflow including seeds that were used to create it. - -You can use () to change emphasis of a word or phrase like: (good code:1.2) or (bad code:0.8). The default emphasis for () is 1.1. To use () characters in your actual prompt escape them like \\( or \\). - -You can use {day|night}, for wildcard/dynamic prompts. With this syntax "{wild|card|test}" will be randomly replaced by either "wild", "card" or "test" by the frontend every time you queue the prompt. To use {} characters in your actual prompt escape them like: \\{ or \\}. - -Dynamic prompts also support C-style comments, like `// comment` or `/* comment */`. - -To use a textual inversion concepts/embeddings in a text prompt put them in the models/embeddings directory and use them in the CLIPTextEncode node like this (you can omit the .pt extension): - -```embedding:embedding_filename.pt``` - - -## How to show high-quality previews? - -Use ```--preview-method auto``` to enable previews. - -The default installation includes a fast latent preview method that's low-resolution. To enable higher-quality previews with [TAESD](https://github.com/madebyollin/taesd), download the [taesd_decoder.pth, taesdxl_decoder.pth, taesd3_decoder.pth and taef1_decoder.pth](https://github.com/madebyollin/taesd/) and place them in the `models/vae_approx` folder. Once they're installed, restart ComfyUI and launch it with `--preview-method taesd` to enable high-quality previews. - -## How to use TLS/SSL? -Generate a self-signed certificate (not appropriate for shared/production use) and key by running the command: `openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -sha256 -days 3650 -nodes -subj "/C=XX/ST=StateName/L=CityName/O=CompanyName/OU=CompanySectionName/CN=CommonNameOrHostname"` - -Use `--tls-keyfile key.pem --tls-certfile cert.pem` to enable TLS/SSL, the app will now be accessible with `https://...` instead of `http://...`. - -> Note: Windows users can use [alexisrolland/docker-openssl](https://github.com/alexisrolland/docker-openssl) or one of the [3rd party binary distributions](https://wiki.openssl.org/index.php/Binaries) to run the command example above. -

If you use a container, note that the volume mount `-v` can be a relative path so `... -v ".\:/openssl-certs" ...` would create the key & cert files in the current directory of your command prompt or powershell terminal. - -## Support and dev channel - -[Discord](https://comfy.org/discord): Try the #help or #feedback channels. - -[Matrix space: #comfyui_space:matrix.org](https://app.element.io/#/room/%23comfyui_space%3Amatrix.org) (it's like discord but open source). - -See also: [https://www.comfy.org/](https://www.comfy.org/) - -## Frontend Development - -As of August 15, 2024, we have transitioned to a new frontend, which is now hosted in a separate repository: [ComfyUI Frontend](https://github.com/Comfy-Org/ComfyUI_frontend). This repository now hosts the compiled JS (from TS/Vue) under the `web/` directory. - -### Reporting Issues and Requesting Features - -For any bugs, issues, or feature requests related to the frontend, please use the [ComfyUI Frontend repository](https://github.com/Comfy-Org/ComfyUI_frontend). This will help us manage and address frontend-specific concerns more efficiently. - -### Using the Latest Frontend - -The new frontend is now the default for ComfyUI. However, please note: - -1. The frontend in the main ComfyUI repository is updated fortnightly. -2. Daily releases are available in the separate frontend repository. - -To use the most up-to-date frontend version: - -1. For the latest daily release, launch ComfyUI with this command line argument: - - ``` - --front-end-version Comfy-Org/ComfyUI_frontend@latest - ``` - -2. For a specific version, replace `latest` with the desired version number: - - ``` - --front-end-version Comfy-Org/ComfyUI_frontend@1.2.2 - ``` - -This approach allows you to easily switch between the stable fortnightly release and the cutting-edge daily updates, or even specific versions for testing purposes. - -### Accessing the Legacy Frontend - -If you need to use the legacy frontend for any reason, you can access it using the following command line argument: - +```bash +install.bat ``` ---front-end-version Comfy-Org/ComfyUI_legacy_frontend@latest +((( use `install-n.bat` if you want to install for miopen-triton combo for high end gpu's ))) + +to start for later use (or create a shortcut to) : + +```bash +comfyui.bat +``` +((( use `comfyui-n.bat` if you want to use miopen-triton combo for high end gpu's, that basically changes the attention to pytorch attention which works with flash attention ))) + + --- To use sage-attention , you have to change the "--use-pytorch-cross-attention" to "--use-sage-attention". My advice is make a seperate batch file for all different attention types instead of changing them. + --- You can use "--use-pytorch-cross-attention", "--use-quad-cross-attention" , "--use-flash-attention" and "--use-sage-attention" . Also you can activate flash or sage with the help some nodes from pytorch attention. + +also for later when you need to repatch zluda (maybe a torch update etc.) you can use: + +```bash +patchzluda.bat ``` -This will use a snapshot of the legacy frontend preserved in the [ComfyUI Legacy Frontend repository](https://github.com/Comfy-Org/ComfyUI_legacy_frontend). +((( `patchzluda-n.bat` for miopen-triton setup))) -# QA +- The first generation would take around 10-15 minutes, there won't be any progress or indicator on the webui or cmd + window, just wait. Zluda creates a database for use with generation with your gpu. -### Which GPU should I buy for this? +> [!NOTE] +> **This might happen with torch changes , zluda version changes and / or gpu driver changes.** -[See this page for some recommendations](https://github.com/comfyanonymous/ComfyUI/wiki/Which-GPU-should-I-buy-for-ComfyUI) +## Troubleshooting + +- `CUDA device detected: None` , if seeing this error with the new install-n , make sure you are NOT using the amd driver 25.5.1 . Use a previous driver, it has problems with zluda. +- `RuntimeError: CUDNN_BACKEND_OPERATIONGRAPH_DESCRIPTOR: cudnnFinalize FailedmiopenStatusInternalError cudnn_status: miopenStatusUnknownError` , if this is encountered at the end, while vae-decoding, use tiled-vae decoding either from official comfy nodes or from Tiled-Diffussion (my preference). Also vae-decoding is overall better with tiled-vae decoding. +- If you installed miopen-triton setup with install.n.bat , getting ":: Triton core imported successfully , :: Running Triton kernel test... , :: Triton test failed , :: Triton available but failed verification" Do this to fix it : + * Copy "libs" folder from python install directory under(C:\Users\username\AppData\Local\Programs\Python\Python310) Or 311 , whatever python you are using, to under "comfyui-zluda\venv" so , + * For example : "C:\Users\username\AppData\Local\Programs\Python\Python310\libs" to "d:\Comfyui-Zluda\venv\* Beware, there are two similar folders under venv , "Lib" and "Library" , so this would be a similarly named folder , don't mistake them. + Then try running comfy again. +- DO NOT use non-english characters as folder names to put comfyui-zluda under. +- Wipe your pip cache "C:\Users\USERNAME\AppData\Local\pip\cache" You can also do this when venv is active with : + `pip cache purge` +- `xformers` isn't usable with zluda so any nodes / packages that require it doesn't work. `Flash attention` + doesn't work. +- Have the latest drivers installed for your amd gpu. **Also, Remove Any Nvidia Drivers** you might have from previous + nvidia gpu's. +- If you see zluda errors make sure these three files are inside "ComfyUI-Zluda\venv\Lib\site-packages\torch\lib\" + `cublas64_11.dll (231kb)` `cusparse64_11.dll (199kb)` `nvrtc64_112_0.dll (129kb)` If they are there but much bigger in size please run : `patchzluda.bat` (this is for zluda 3.8.4, other versions might be different sizes) +- If for some reason you can't solve with these and want to start from zero, delete "venv" folder and re-run + `install.bat` +- If you can't git pull to the latest version, run these commands, `git fetch --all` and then + `git reset --hard origin/master` now you can git pull +- Problems with `caffe2_nvrtc.dll`: if you are sure you properly installed hip and can see it on path, please DON'T use + python from windows store, use the link provided or 3.11 from the official website. After uninstalling python from + windows store and installing the one from the website, be sure the delete venv folder, and run install.bat once again. +- `rocBLAS`-error: If you have an integrated GPU by AMD (e.g. AMD Radeon(TM) Graphics) you need to add `HIP_VISIBLE_DEVICES=1` to your + environment variables. Other possible variables to use : `ROCR_VISIBLE_DEVICES=1` `HCC_AMDGPU_TARGET=1` . This basically tells it to use 1st gpu -this number could be different if you have multiple gpu's- + Otherwise it will default to using your iGPU, which will most likely not work. This behavior is caused by a bug in the ROCm-driver. +- Lots of other problems were encountered and solved by users so check the issues if you can't find your problem here. + +## Credits + +- [ComfyUI](https://github.com/comfyanonymous/ComfyUI) +- [Zluda Wiki from SdNext](https://github.com/vladmandic/automatic/wiki/ZLUDA) +- [Brknsoul for Rocm Libraries](https://github.com/brknsoul/ROCmLibs) +- [Lshqqytiger](https://github.com/lshqqytiger/ZLUDA) +- [LeagueRaINi](https://github.com/LeagueRaINi/ComfyUI) +- [ComfyUI-Manager](https://github.com/ltdrdata/ComfyUI-Manager)
