T2I-Adapter-SDXL - Depth-MiDaS

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 depth 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
  1. Images are first downloaded into the appropriate control image format.
  2. The control image and prompt are passed to the StableDiffusionXLAdapterPipeline.

Let's have a look at a simple example using the Canny Adapter.
