Args:
    path: Path to directory.
    glob: A glob pattern or list of glob patterns to use to find files.
        Defaults to "**/[!.]*" (all files except hidden).
    exclude: A pattern or list of patterns to exclude from results.
        Use glob syntax.
    silent_errors: Whether to silently ignore errors. Defaults to False.
    load_hidden: Whether to load hidden files. Defaults to False.
    loader_cls: Loader class to use for loading files.
      Defaults to UnstructuredFileLoader.
    loader_kwargs: Keyword arguments to pass to loader_cls. Defaults to None.
    recursive: Whether to recursively search for files. Defaults to False.
    show_progress: Whether to show a progress bar. Defaults to False.
    use_multithreading: Whether to use multithreading. Defaults to False.
    max_concurrency: The maximum number of threads to use. Defaults to 4.
    sample_size: The maximum number of files you would like to load from the
        directory.
    randomize_sample: Shuffle the files to get a random sample.
    sample_seed: set the seed of the random shuffle for reproducibility.

Examples:

    .. code-block:: python
        from langchain_community.document_loaders import DirectoryLoader

        # Load all non-hidden files in a directory.
        loader = DirectoryLoader("/path/to/directory")

        # Load all text files in a directory without recursion.
        loader = DirectoryLoader("/path/to/directory", glob="*.txt")

        # Recursively load all text files in a directory.
        loader = DirectoryLoader(
            "/path/to/directory", glob="*.txt", recursive=True
        )

        # Load all files in a directory, except for py files.
        loader = DirectoryLoader("/path/to/directory", exclude="*.py")

        # Load all files in a directory, except for py or pyc files.
        loader = DirectoryLoader(
