FLUX Finetuning scripts

This repository provides training scripts for Flux model by Black Forest Labs.
XLabs AI team is happy to publish fune-tuning Flux scripts, including:

  • LoRA 🔥
  • ControlNet 🔥

ComfyUI

See our github for comfy ui workflows. Example Picture 1

Requirements

  1. Python >= 3.10
  2. PyTorch >= 2.1
  3. HuggingFace CLI is required to download our models: huggingface-cli login

Installation Guide

  1. Clone our repo:
git clone https://github.com/XLabs-AI/x-flux.git
  1. Create new virtual environment:
python3 -m venv xflux_env
source xflux_env/bin/activate
  1. Install our dependencies by running the following command:
pip install -r requirements.txt

Training

We trained LoRA and ControlNet models using DeepSpeed!
It's available for 1024x1024 resolution!

Models

We trained IP-Adapter, Canny ControlNet, Depth ControlNet, HED ControlNet and LoRA checkpoints for FLUX.1 [dev]
You can download them on HuggingFace:

Also, our models are avaiable at civit.ai

LoRA

accelerate launch train_flux_lora_deepspeed.py --config "train_configs/test_lora.yaml"

ControlNet

accelerate launch train_flux_deepspeed_controlnet.py --config "train_configs/test_canny_controlnet.yaml"

Training Dataset

Dataset has the following format for the training process:

├── images/
│    ├── 1.png
│    ├── 1.json
│    ├── 2.png
│    ├── 2.json
│    ├── ...

Example images/*.json file

A .json file contains "caption" field with a text prompt.

{
    "caption": "A figure stands in a misty landscape, wearing a mask with antlers and dark, embellished attire, exuding mystery and otherworldlines"
}

Inference

To test our checkpoints, use commands presented below.

IP-Adapter

python3 main.py \
 --prompt "wearing glasses" \
 --ip_repo_id XLabs-AI/flux-ip-adapter --ip_name flux-ip-adapter.safetensors --device cuda --use_ip \

Low memory mode

Use quantized version Flux-dev-F8 to achieve lower VRAM usage (22 GB) with --offload and --model_type flux-dev-fp8 settings:

python3 main.py \
 --offload --model_type flux-dev-fp8 \
  --lora_repo_id XLabs-AI/flux-lora-collection --lora_name realism_lora.safetensors \
 --guidance 4 \
 --prompt "A handsome girl in a suit covered with bold tattoos and holding a pistol"
