Chroma Inference/Generation
Prerequisites
24 GB Cards
- Get Chroma HD Flash and put it in diffusion_models in ComfyUI's models folder.
- Get a text encoder, then place it in ComfyUI's text encoder's folder
a. T5 FP16 (for >=32GB RAM)
b. T5 FP8 (for <32GB RAM) - Only required for the Upscale/Face detailer workflow Upscaler model 4x_NMKD-Siax_200k.pth
- Only required for the upscale/face detailer workflow [face_yolov8n-seg2_60.pthttps://huggingface.co/jags/yolov8_model_segmentation-set/resolve/main/face_yolov8n-seg2_60.pt)
12 GB Cards
Coming Soon™
Chroma Workflows
Both of these load the full models so 24GB is required. You can modify these to load GGUF quantizations if need be. I'll post a few lower memory workflows soon.
Basic Chroma Workflow
Chroma HD Flash with Upscale and Facedetailer
Chroma Training
Training Environment Setup
This is assuming a cloud GPU setup like runpod.io or vast.ai. You may have to make modifications for running locally.
Data Collection and Training Settings
As of now, I just follow the same data collection techniques from the SDXL world:
- Collect 20-70 images of the target person.
- Caption them with natural language and put your trigger tag at the front. For example:
ava max, an iphone selfie photograph of a woman with blonde hair...
- Grab the following TOML and training command for kohya.
- update lora_config.toml to point to the folders of your images. Just use the full path to the image folder. For example
/workspace/img/1_avamax
- Do a find/replace on the string
person-name
and replace with whatever you want. For example:ava-max
. - run train.sh
Available LoRAs
Please bear in mind that these are going to be slightly larger in filesize than SDXL. I've experiemented with smaller dimensions but the likeness never looks as good.
