tfds.folder_dataset.compute_split_info

Compute the split info on the given files.

tfds.folder_dataset.compute_split_info(
    *,
    out_dir: Optional[epath.PathLike] = None,
    filename_template: tfds.core.ShardedFileTemplate
) -> List[tfds.core.SplitInfo]

Compute the split info (num shards, num examples,...) metadata required by tfds.folder_dataset.write_metadata.

See documentation for usage: https://www.tensorflow.org/datasets/external_tfrecord

Args
out_dir	Output directory where to save the metadata. It should be available from the apache beam workers. If not set, apache beam won't be used (only available with some file formats).
filename_template	filename template of the splits. The template should have set the data_dir because this is used to compute the split info.

Returns
split_infos	The list of tfds.core.SplitInfo.
