# FLUX.1-dev-ControlNet-Union-Pro

This repository contains an unified ControlNet for FLUX.1-dev model jointly released by researchers from [InstantX Team](https://huggingface.co/InstantX) and [Shakker Labs](https://huggingface.co/Shakker-Labs).

# Model Cards
- This checkpoint is a Pro version of [FLUX.1-dev-Controlnet-Union](https://huggingface.co/InstantX/FLUX.1-dev-Controlnet-Union) trained with more steps and datasets.
- This model supports 7 control modes, including canny (0), tile (1), depth (2), blur (3), pose (4), gray (5), low quality (6).
- The recommended controlnet_conditioning_scale is 0.3-0.8.
- This model can be jointly used with other ControlNets.

# Inference
Please install `diffusers` from [the source](https://github.com/huggingface/diffusers), as [the PR](https://github.com/huggingface/diffusers/pull/9175) has not been included in currently released version yet.

# Multi-Controls Inference
```python
import torch
from diffusers.utils import load_image

from diffusers import FluxControlNetPipeline, FluxControlNetModel, FluxMultiControlNetModel

base_model = 'black-forest-labs/FLUX.1-dev'
controlnet_model_union = './Shakker-Labs/FLUX.1-dev-Controlnet-Union'

controlnet_union = FluxControlNetModel.from_pretrained(controlnet_model_union, torch_dtype=torch.bfloat16)
controlnet = FluxMultiControlNetModel([controlnet_union]) # we always recommend loading via FluxMultiControlNetModel

pipe = FluxControlNetPipeline.from_pretrained(base_model, controlnet=controlnet, torch_dtype=torch.bfloat16)
pipe.to("cuda")

prompt = 'a young girl'
control_image_depth = load_image("https://huggingface.co/InstantX/FLUX.1-dev-Controlnet-Union/resolve/main/images/depth.jpg")
control_mode_depth = 2

control_image_canny = load_image("https://huggingface.co/InstantX/FLUX.1-dev-Controlnet-Union/resolve/main/images/canny.jpg")
control_mode_canny = 0

width, height = control_image.size

image = pipe(
    prompt, 
    control_image=[control_image_depth, control_image_canny],
    control_mode=[control_mode_depth, control_mode_canny],
    width=width,
    height=height,
    controlnet_conditioning_scale=[0.5, 0.5],
    num_inference_steps=24, 
    guidance_scale=3.5,
    generator=torch.manual_seed(42),
).images[0]
```

We also support loading multiple ControlNets as before, you can load as
```python
controlnet_model_union = './Shakker-Labs/FLUX.1-dev-Controlnet-Union'
controlnet_union = FluxControlNetModel.from_pretrained(controlnet_model_union, torch_dtype=torch.bfloat16)

controlnet_model_depth = './Shakker-Labs/FLUX.1-dev-Controlnet-Depth'
controlnet_depth = FluxControlNetModel.from_pretrained(controlnet_model_depth, torch_dtype=torch.bfloat16)

controlnet = FluxMultiControlNetModel([controlnet_union, controlnet_depth])

# set mode to None for other ControlNets
control_mode=[2, None]
```
