T2I-Adapter-SDXL - Openpose
T2I Adapter is a network providing additional conditioning to stable diffusion. Each t2i checkpoint takes a different type of conditioning as input and is used with a specific base stable diffusion checkpoint.
This checkpoint provides conditioning on openpose for the StableDiffusionXL checkpoint. This was a collaboration between Tencent ARC and Hugging Face.

Example
To get started, first install the required dependencies:
pip install -U git+https://github.com/huggingface/diffusers.git
pip install -U controlnet_aux==0.0.7 # for conditioning models and detectors
pip install transformers accelerate safetensors
- Images are first downloaded into the appropriate control image format.
- The control image and prompt are passed to the
StableDiffusionXLAdapterPipeline
.
Let's have a look at a simple example using the Openpose Adapter.
