Is there any example of `dataset_1024_bs1.toml`

Start with the command in the issue and library/config_util.py at line 651 to understand how --dataset_config resolves filenames. Check the repository’s examples and documentation for dataset_1024_bs1.toml; done means documenting or supplying the referenced configuration so the shown command no longer points to a missing file.
