🚀 ComfyUI Auto-Installer — v5 (Python Rewrite)
Version 5 is a full rewrite from the ground up in Python, replacing all the PowerShell scripts from previous versions. It's cross-platform, faster, smarter, and now ships with a TUI manager, Docker images, and GPU-optimized inference out of the box.
If you are upgrading from the PowerShell version (v4.x), a one-command migration preserves all your models, outputs, and custom nodes: irm https://get.umeai.art/migrate.ps1 | iex
⚡ Quick Start (One-Liner)
Windows (PowerShell):
irm https://get.umeai.art/comfyui.ps1 | iexLinux / macOS:
curl -fsSL https://get.umeai.art/comfyui.sh | sh
Only requires Git — everything else (Python, uv, dependencies) is handled automatically.
✨ What's New in v5
Full Python rewrite — no more PowerShell dependency
Cross-platform — Windows, Linux, macOS, and Docker
TUI Manager — interactive terminal UI to launch, update, download models, and configure settings
VRAM-aware model catalog — 7 model families with quantization recommendations based on your GPU
GPU auto-detection — NVIDIA (CUDA 13.0/12.8), AMD (ROCm/DirectML), Apple Silicon (MPS)
SageAttention 2 + 3 — pre-compiled wheels including RTX 50XX Blackwell support
One-click update — update ComfyUI, all nodes, and dependencies with a single command
Model security scanner — detects malicious pickle code in .ckpt/.pt files
Junction architecture — models and outputs persist independently from ComfyUI updates
Docker ready — 4 image variants including a cloud version with JupyterLab for RunPod

[2025-07-07 21:29:55.660] Error running sage attention: [WinError 2] The system cannot find the file specified, using pytorch attention instead. The error keeps going until the gen is finished. Any ideas? I'm on a GTX 3090? MSVC is loaded and set. Same with NVCC, Cuda 12.8, Python 3.12. Am I missing something?
Can pytorch version 2.7.0+cu128 be replaced with 2.7.1? Will there be flux kontext? And workflows for it? wan 2.1 loop, extend with vace? New speed loras? FusionX?
Thanks for this feature list. I'll work on implementing all of this.
I'm doing a fresh install with the new 3.0v and says push location not found for x:/comfyui. if anyone know please 🙏
Can you send me the log file or go in my discord : https://discord.gg/airt
@UmeAiRT I think the problem was on my end it is already downloading the models 😁 thanks you much love 🫶
Lots of errors.

Why does it no longer use portable version?
I came here to ask the same question
I hesitated a lot, but the portable version has many limitations and compatibility issues with certain advanced modules. This installation method is cleaner and optimized. In addition, it allows for the same installation logic for Linux users (or Runpod for example).

I am receiving the same error
I moved from huggingface to github and some people were having trouble downloading. I released a patch today that should fix this.
@UmeAiRT I get this same issue. It worked at first, but after relaunching it gives this issue. Today is my first day using your auto installer so I'm on the latest version.
ComfyUI crashes when trying to load the default workflow. Removing ComfyUI-Lora-Manager fixed the issue for me. Other than that, good install experience. 👌

Anyone have the same issue?
Failed to initialize database. Please ensure you have installed the latest requirements. If the error persists, please report this as in future the database will be required: (sqlite3.OperationalError) unable to open database file
Yes, I get the same error on 3060
Try creating a folder named 'user' inside of the base ComfyUI folder. If ComfyUI still isn't starting, try taking the 'ComfyUI-Lora-Manager' folder out of the custom_nodes folder. That fixed the issue for me.
@gudMorganFreeman Wow! That works for me,thx for helping!
I had added ComfyUI-Lora-Manager but it causes a lot of problems so I removed it
ModuleNotFoundError: No module named 'triton'
Press any key to continue . . . 😥
"UPDATE" the python_embeded folder wasn't in the auto installation I just pull the entered folder from another working system as well the run_nvidia_gpu and run_cpu files and instal pip segmentation. still haven't install triton on this window but at least is working 😁
@vcoloraimachine970 You shouldn't need python_embeded. I uploaded a patch, can you re-run the script in a new folder?
UmeAiRT thank you so much you are a legend 😊
Model downloader still doesn´t work
You're better off downloading models yourself. I personally don't use the models comfyui's templates ask for anyways as they're vram hungry. Even the wan vace example doesn't make much sense to me. Look for a wan2.1 vace gguf model instead. Way easier on vram and ram limited systems.
I changed the download method yesterday, for me it works on a completely blank virtual machine.
first time iv had issues with this install. my issue being Sage not installed , i thought windows was blocking it but after looking nothing has been blocked, trying to do a manual install of sage and i can not find the " update" folder anywhere for the manual install files, unsure what to do, or i just install comfyui without using this install method :(
I changed the version of sageattention today, as well as its installation method. You can try a full installation again; it will take a little longer but should be fully functional.
@UmeAiRT okay then thank you so much. Iv used your install now for most of my content. Its such and easy. Just this time it throw that error . Thank you for all your hard work. I for one really appreciate it.
@UmeAiRT also. Its thst download live now. Or are updating the file later. Unsure if your able to just update it without having to upload it to civ again. Really hope that made sense lol
@djacid Since v3 the main script only downloads the latest version of the script from my github
@UmeAiRT after downloading the new update from your Github i still have the same error. " To use the --use-sage-attention feature, the sageattention package must be installed first.
command:
A:\comfyui\ComfyUI\venv\Scripts\python.exe -m pip install sageattention
Press any key to continue . . ." and it doesnt do anything else after that, its was installed in a brand new folder also.
@djacid Can you send me the log file so I can see where the error is coming from?
@UmeAiRT yea sure thing. Give me a sec and ill grab it
same error.
got it work but it runs EXTREMELY slow. 480x274 taking 1hr+
just Patching comfy attention to use sageattn takes an eternity.
New update works very nicely now. I did skip auto install modules, so I can't report on that. Only one error while loading comfyui which doesn't seem to cause any issues.

Some packages may not work. Can I change to 3.10 and it will work?
Is there a reason the new install would be running much slower than the previous one? The last auto-installer (v2.5) seemed to work decently. v3 with the new workflows are taking forever.
it was 5+ hrs for a 400x272 3sec vid that used to take 15min.
I was getting Error running sage attention: CUDA error: no kernel image is available for execution on the device on the v3.0 installer with a 5090.
I was able to resolve it with the following steps. I'm not sure if the xformers reinstall was completely necessary (I don't remember what was installed in the venv to begin with)
1. From the ComfyUI directory, Activate the virtual env with: venv\Scripts\activate
2. Uninstall xformers with: python.exe -m pip uninstall xformers
3. Reinstall xformers for CUDA 12.8 with: python.exe -m pip install -U xformers --index-url https://download.pytorch.org/whl/cu128
4. Uninstall sageattention with: pip uninstall sageattention
5. Manually recompile sageattention with elevated compute capability (12.0 for 5090 -- see https://developer.nvidia.com/cuda-gpus if you have a different GPU). Note that the setup.py install command will take some time -- 10 - 15 minutes.
-- 5a. Clone the SageAttention repo - I put it in venv, maybe not the best?
cd venv
git clone https://github.com/thu-ml/SageAttention
-- 5b. Enter the cloned repo, set the TORCH_CUDA_ARCH_LIST environment variable, and compile:
cd SageAttention
set TORCH_CUDA_ARCH_LIST=12.0
python setup.py install
-- 5c. (optional) validate with: pip show sageattention
6. Run the ComfyUI startup batch as usual
According to GPT, you can put multiple compute capabilities in the environment variable delimited by semicolons if you're not sure which version to use (though I have not validated this):
set TORCH_CUDA_ARCH_LIST=8.9;9.0;12.0
Hope this helps anyone in a similar predicament!
sageattention won't install.
therefore, UmeAiRT-Start-ComfyUI.bat does not start this comfyui installation

nevermind. worked the second attempt
firsak Today I sent a lot of updates which may have caused problems. Now everything is back to normal but you have to use CUDA 12.9 from now on.
UmeAiRT Hi mate, kindly was going to let you know that present install for nunchaku is for Cuda 12.8 install, if you wanted to update your installer to the latest nightly for it with Cuda 12.9. Best Regards, and thanks for all your work! I've learned literally EVERYTHING I know about AI from your guides!
Summitatem Thanks, I try to do my best with the guides, I'm happy if they helped you. My script install Nunchaku for PyTorch 2.8 and Python 3.12, no reference to a CUDA version
So my main computer has 64GB DDR4 ram and my GPU is AMD Radeon RX 7900 XTX with 24GB ram. But as i understand, this only supports Nvidia right? Then i go to my laptop which is a Lenovo Thinkpad P1 Gen. 4 with 32GB ram and Nvidia GPU. Then it says sageattention issues..?
Is there a solution for my AMD GPU on my main computer? If not how to i correct the sageattention issue?
Upgrade from crap amd to Nvidia. AMD is only for budget gaming and non-ai.
currently the script stalls forever at
```
# xformers
Write-Log " - Installing xformers from source... (This may take several minutes)"
$env:FORCE_CUDA = "1"
Invoke-AndLog "$venvPython" "-m pip install --no-build-isolation --verbose git+https://github.com/facebookresearch/xformers.git@main#egg=xformers"
$env:FORCE_CUDA = $null
```
because https://github.com/facebookresearch/xformers.git@main#egg=xformers goes to a blank "not found" page... not sure what to do about it.
I closed the script and manually continued in powershell from where it left off. it seems like xformers is installed somehow anyway.
o0oradaro0o The script warns that xformers and sageattention can take a long time to install. If you close the script before it is finished, you will not have everything working.
I appreciate your script so I don't mean to be snarky but forever is a long time. The link is literally down. You can click it and check. The link you have in the code directs to a GitHub page that simply says "not found." The documentation on Facebook's page points to the same link so I don't think it's an issue with your script. I think they just have broken something on their end. Until that link is fixed though, your script will stall out forever on that step, not just for a few minutes.
o0oradaro0o Because link is not down : "https://github.com/facebookresearch/xformers.git" is the link and "@main#egg=xformers" instruction for pip. On my Notebook i have to wait more than 15min.
UmeAiRT thank you for taking the time to educate me and sorry for misleading you. The issue must have been with my environment as I did wait 30 minutes and saw no network or disk activity so I incorrectly assumed it was an issue with the script but following the remaining steps manually and everything is working beautifully.
Thank you again for creating this package and taking the time to teach me about pip.
Amazing! Works great! Before that I tried lots of installers and guides and damn, no one works fine, but this - excellent stuff!
2.5 was working well, but after installing 3.0 and trying to run comfyui I get an error: "AssertionError: Torch not compiled with CUDA enabled"
Send me install log please
ModuleNotFoundError: No module named 'torchsde'
What is wrong here ?
does this work on linux?
is anyone else just getting black frame outputs? Both preview and the final output are just pure black
Spent what felt like a whole day installing and uninstalling so many versions of cuda trying to get other installers and methods to work with the new 50xx card and once I saw your note in a comment about cuda 12.9, I got no errors on install and it worked!
One thing though, the custom nodes are all in a folder outside of ComfyUI and so downloaded but not actually installed. Is that a glitch or should I move them into the inclusive folder and run the requirements? I mean, I can also just do an install of manager to the Comfy install and re-install what I want (you have a great, curated set of nodes though, btw) but I figured I'd check.
Thank you, regardless. It's been the most ironic sense of almost buyer's remorse pulling the trigger on this card right before the prices go whack again for who knows how long (system I got Thur went up about $800 Friday). But there's terrible support for 50xx on linux, all kinds of terrible, incomplete, old info everywhere else. People seem to be muscling through but the lack of support in baseline install and setup is baffling to me. So thanks!
It's because my installer dont use ComfyUI folder for custom node and model but a custom one in the root folder
UmeAiRT I wanted to do another note instead of just editing my previous reply, so you wouldn't miss it. I re-ran the script in a separate subfolder after realizing the portable install where I did image creation (I was using your script for a separate video-oriented Comfy install) wasn't using sageattention. This time it worked flawlessly and I've got a fresh ComfyUI with manager and the custom nodes that your script downloaded. It all seems to be working, no errors loading, getting sageattention. You rock!
Where to add the --listen command to run processing on one machine, but UI on another?
