The T2I-Adapter is only available for training with the Stable Diffusion XL (SDXL) model.  
This guide will explore the [train_t2i_adapter_sdxl.py](https://github.com/huggingface/diffusers/blob/main/examples/t2i_adapter/train_t2i_adapter_sdxl.py) training script to help you become familiar with it, and how you can adapt it for your own use-case.  
Before running the script, make sure you install the library from source:  
```bash
git clone https://github.com/huggingface/diffusers
cd diffusers
pip install .
