For unconditional generation, you can provide your own dataset as a folder of images. The training script uses the [`ImageFolder`](https://huggingface.co/docs/datasets/en/image_dataset#imagefolder) builder from 🤗 Datasets to automatically build a dataset from the folder. Your directory structure should look like:  
```bash
data_dir/xxx.png
data_dir/xxy.png
data_dir/[...]/xxz.png

Pass the path to the dataset directory to the `--train_data_dir` argument, and then you can start training:  
```bash
