## What is this ?
|
||||
- an Alpha repo: unofficial **diffusers** integration of the official **SDNQ pipeline** to run in ComfyUI ...because i wanted to compare quality and be even more vram savy
|
||||
|
||||
## Notes:
|
||||
- **use only sdnq nodes** wich you might have to install manually , the other stuf is experimental and does not work
|
||||
- **use only sdnq nodes**
|
||||
you might have to install some pip packages manually, nothing too difficult
|
||||
there are other nodes but they are experimental, ignore them (you might need quanto though)
|
||||
- **install_sdnq.bat** might help on windows because it looks like their toml file has an issue with license (open inside the bat and change paths)
|
||||
- for flash attention find a whl, I did not bother yet as it's ok-ish speedwise, if you need you can try these places:
|
||||
- seems to be **the best place to find them**: https://github.com/mjun0812/flash-attention-prebuild-wheels/releases/tag/v0.5.4
|
||||
- prebuilt wheels https://github.com/mjun0812/flash-attention-prebuild-wheels/releases/tag/v0.4.10 (i have used this one)

||||
- prebuilt wheels https://huggingface.co/Kijai/PrecompiledWheels/tree/main
|
||||
- prebuilt wheels https://huggingface.co/lldacing/flash-attention-windows-wheel/tree/main
|
||||
- compile does not work (for me)
|
||||
- you might need to **install the latest diffusers manually via git to support the pipeline** (from the embedded python folder):
|
||||
python.exe -m pip install git+https://github.com/huggingface/diffusers.git
|
||||
- check requirements for what is needed (quanto is not needed but you might have trouble as there are multiple nodes here)
|
||||
- weights are downloaded by diffusers on first run for sdnq nodes
|
||||
- some option dont work or i did not finish porting, test.
|
||||
- only tested on windows

note: this does not use memory management from comfy, so use carefully. memory footprint is around 7gb vram more or less, you can safely run up to 2048x2048

note: this does not use ComfyUI memory management, so use carefully. Ißve added an option to unload but did not test it not sure it works.
