## Using HunyuanDiT ControlNet


### Instructions

 The dependencies and installation are basically the same as the [**base model**](https://huggingface.co/Tencent-Hunyuan/HunyuanDiT-v1.1).

 We provide three types of ControlNet weights for you to test: canny, depth and pose ControlNet.
 
 Download the model using the following commands:

```bash
cd HunyuanDiT
# Use the huggingface-cli tool to download the model.
# We recommend using distilled weights as the base model for ControlNet inference, as our provided pretrained weights are trained on them.
huggingface-cli download Tencent-Hunyuan/HYDiT-ControlNet --local-dir ./ckpts/t2i/controlnet
huggingface-cli download Tencent-Hunyuan/Distillation-v1.1 ./pytorch_model_distill.pt --local-dir ./ckpts/t2i/model

# Quick start
python3 sample_controlnet.py  --no-enhance --load-key distill --infer-steps 50 --control_type canny --prompt "在夜晚的酒店门前，一座古老的中国风格的狮子雕像矗立着，它的眼睛闪烁着光芒，仿佛在守护着这座建筑。背景是夜晚的酒店前，构图方式是特写，平视，居中构图。这张照片呈现了真实摄影风格，蕴含了中国雕塑文化，同时展现了神秘氛围" --condition_image_path controlnet/asset/input/canny.jpg --control_weight 1.0
```

### Training

We utilize [**DWPose**](https://github.com/IDEA-Research/DWPose) for pose extraction. Please follow their guidelines to download the checkpoints and save them to `hydit/annotator/ckpts` directory. We provide serveral commands to quick install:
```bash
mkdir ./hydit/annotator/ckpts
wget -O ./hydit/annotator/ckpts/dwpose.zip https://dit.hunyuan.tencent.com/download/HunyuanDiT/dwpose.zip
unzip ./hydit/annotator/ckpts/dwpose.zip -d ./hydit/annotator/ckpts/
```
Additionally, ensure that you install the related dependencies.
```bash
pip install matplotlib==3.7.5
pip install onnxruntime_gpu==1.16.3
pip install opencv-python==4.8.1.78
```


We provide three types of weights for ControlNet training, `ema`, `module` and `distill`, and you can choose according to the actual effects. By default, we use `distill` weights. 

Here is an example, we load the `distill` weights into the main model and conduct ControlNet training. 

If you want to load the `module` weights into the main model, just remove the `--ema-to-module` parameter.

If apply multiple resolution training, you need to add the `--multireso` and `--reso-step 64` parameter. 

```bash
task_flag="canny_controlnet"                                # task flag is used to identify folders.
control_type=canny
resume=./ckpts/t2i/model/                                    # checkpoint root for resume
index_file=path/to/your/index_file

image_size=1024                                              # training image resolution
grad_accu_steps=2                                            # gradient accumulation

lr=0.0001                                                    # learning rate
ckpt_every=10000                                             # create a ckpt every a few steps.
ckpt_latest_every=5000                                       # create a ckpt named `latest.pt` every a few steps.
