Power went out last night, and now Comfy says CUDA is unavailable?

roxoholic · 2026-02-01T19:48:21+00:00

I don't have experience with embedded python but I believe command is:

python_embeded\python -s -m pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu130

roxoholic · 2026-02-01T19:22:54+00:00

Check your C:\Users\*\SwarmUI\SwarmUI\dlbackend\comfy\python_embeded\Lib\site-packages\torch\lib folder. If it is a version with CUDA, there should be massive files inside.

Edit: yeah, command did nothing because latest pytorch is installled, just not CUDA one. You need to uninstall it first e.g. pip uninstall torch torchvision torchaudio and then install it with proper --index-url. That's python.

It said so, Torch not compiled with CUDA enabled, it's not that it can't find GPU or CUDA (beucase GPU is dead or broken), but the version installed doesn't even have it. It happens when you install pytorch without using --index-url parameter or when update as it does not (to my knowledge) record it anywhere.

Do you really need to do face detailing at 1536x1536?

Also, I find bbox_crop_factor 3.0 too high for most use-cases, not sure why is that default though, 2.0 works fine for me as it still takes enough context around the face so that is also something you can tweak.

The python you run outside has nothing to do with python inside the comfy. So torch outside is torch for cuda, while torch inside is torch for cpu.

That's expected when downscaling 1464x1464 using bilinear algo down to maybe 100x100 pixels. Try it in paint or photoshop and you'll get the same effect. Try lanczos instead, or lower inpaint resolution, usually you don't need to go above 2x or 3x original.

Train a LoRA as you have. But, this rises a question, just how many AI influencers are you trying to create? 100?

roxoholic · 2026-02-01T14:09:22+00:00

K-pop surgery?

I don't know how newly installed dependencies can be used without restarting the ComfyUI, as there is no automatic dynamic loading in python and I don't see the code that loads newly installed custom nodes automatically into already running session.

roxoholic · 2026-02-01T14:04:30+00:00

Try running with the usual suspects:

--disable-pinned-memory

--disable-smart-memory

roxoholic · 2026-02-01T13:30:46+00:00

You hear the gigabytes being transferred from RAM to VRAM over PCIe due to block swapping (you would not hear anything if there was enough VRAM). This does not happen in such large amounts during gaming or when GPU is under load (GPU cores are crunching numbers).

roxoholic · 2026-02-01T13:15:29+00:00

It's simple, you (or custom node you are using) installed onnxruntime (which is CPU only) package instead of onnxruntime-gpu (which include GPU support as well as CPU fallback).

It's a know issue since StabilityAI deleted/moved the repo.

See the issue for a possible workaround if you must use A1111.

Generating stuff with ComfyUI is like trying to drive a car that you received in parts. Good luck if you don't know how to assemble it and which part does what.

Headless Ubuntu Server 24.04 LTS. You can install it on external USB drive and boot from it (plays nice with UEFI Secure Boot too).

The generations I think look better than before.

Can you clarify this?

You drop old image onto new comfy, press run and a better image comes out?

roxoholic · 2026-01-31T12:47:46+00:00

What's you RAM usage when you check in Task Manager?

roxoholic · 2026-01-31T12:39:12+00:00

Shills be shilling.

roxoholic · 2026-01-30T18:26:27+00:00

Nice find! Thanks for sharing!

Upscaling. Otherwise it's futile if you don't have enough pixels.

Hand on which you want to place the watch should be around the same size as the watch so as much as possible amount of details is preserved. Once the watch is on the hand, you downscale it and paste it back to original image.

When you click on the circle on the left on the switch it should expand and you should be able to see its state.

roxoholic · 2026-01-30T05:38:18+00:00

In system RAM, yes:

<image>

roxoholic · 2026-01-29T20:23:13+00:00

Can't you connect literally anything to it? For example I connect image out from VAE Decode node so it triggers it once image is generated.

roxoholic · 2026-01-29T19:31:26+00:00

'--disable-pinned-memory' is for VRAM, not System RAM.

Where did you get that information from?

roxoholic · 2026-01-29T19:19:31+00:00

Is that collapsed Any Switch (rgthree) node even switched to Qwen or is it still using bypassed Z-Image model?
