Installation
-
Clone this repo into
custom_nodes
folder. -
Install dependencies:
pip install -r requirements.txt
or if you use the portable install, run this in ComfyUI_windows_portable -folder:python_embeded\python.exe -m pip install -r ComfyUI\custom_nodes\ComfyUI-LuminaWrapper\requirements.txt
Note: Sampling is slow without flash_attn
!
For Linux users this doesn't mean anything but pip install flash_attn
.
However doing same on Windows currently will most likely fail if you do not have a build environment setup, and even if you do it can take an hour to build. Alternative for Windows can be pre-built wheels from here, has to match your python environment: https://github.com/bdashore3/flash-attention/releases
If flash_attn is not installed, attention code will fallback to torch SDP attention, which is at least twice as slow and memory hungry.
Text encoder setup
Lumina-next uses Google's Gemma-2b -LLM: https://huggingface.co/google/gemma-2b To download it you need to consent to their terms. This means having Hugginface account and requesting access (it's instant once you do it).
Either download it yourself to ComfyUI/models/LLM/gemma-2b
(don't need the gguf -file) or let the node autodownload it.
Lumina models
The nodes support the Lumina-next text to image models:
https://huggingface.co/Alpha-VLLM/Lumina-Next-SFT
https://huggingface.co/Alpha-VLLM/Lumina-Next-T2I
They are automatically downloaded to ComfyUI/models/lumina

The workflows are including in the examples -folder
