Reference Issues/PRs
Fixes #27447.
What does this implement/fix? Explain your changes.
This PR changes the parameter constraints of the dataset fetchers from
[str, None]to[str, os.PathLike, None].Any other comments?
The functions do have the ability to handle
os.PathLike, but previouslyvalidate_paramsis disabling it. The unit test also only makes sure that it is able to handle thesedata_home, but does check explicitly for each data fetcher. Not sure if this is sufficient.
