def add_fuse_directory_markers_to_cloud_storage(client, bucket_name, root_path="", pbar=True):
    """
    Create gcsfuse directory markers from a bucket and root path

    Parameters
    -----------
    client : google.cloud.storage.Client
        See the [google.cloud.storage.Client](https://googleapis.dev/python/storage/latest/client.html) docs for help setting this up.
    bucket_name : str
        name of the bucket on gcs
    root_path : str, optional
        prefix of "directories" below which to create the directory markers

    Examples
    ---------

    The following will create directory markers for all directories within gs://my-bucket/path/to/root,
    where directories are indicated by the presence of blobs with directory separators (`'/'`) in the
    path. Empty directories will not be created, since these cannot exist on google cloud storage.
