The croissant metadata on HF are generated automatically for datasets in supported formats like Parquet or [ImageFolder (folder of images and a metadata file )](https://huggingface.co/docs/datasets/v3.5.0/en/image_dataset#imagefolder). If you convert your dataset to Parquet, or if you structure your dataset as a ImageFolder, the croissant metadata will be available.

There is no way to automatically get a croissant metadata file for a dataset based on a python script.
