## Description Add `__init__` for unstructured loader of epub/image/markdown/pdf/ppt/word to restrict the input type to `str` or `Path`. In the [signature](https://python.langchain.com/api_reference/community/document_loaders/langchain_community.document_loaders.markdown.UnstructuredMarkdownLoader.html) these unstructured loaders receive `file_path: str | List[str] | Path | List[Path]`, but actually they only receive `str` or `Path`. ## Issue None ## Dependencies No changes.

Unstructured loaders, UnstructuredExcelLoader can be used in both

"single" and "elements" mode. If you use the loader in "elements"
