So this arose from the https://github.com/langchain-ai/langchain/pull/18397 problem of document loaders not supporting `pathlib.Path`. This pull request provides more uniform support for Path as an argument. The core ideas for this upgrade: - if there is a local file path used as an argument, it should be supported as `pathlib.Path` - if there are some external calls that may or may not support Pathlib, the argument is immidiately converted to `str` - if there `self.file_path` is used in a way that it allows for it to stay pathlib without conversion, is is only converted for the metadata.

Like other

Unstructured loaders, UnstructuredTSVLoader can be used in both

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

mode, the TSV file will be a single Unstructured Table element.
|
|
If you use the loader in "elements" mode, an HTML representation
|
|
of the table will be available in the "text_as_html" key in the
|
|
document metadata.
