    @HyukjinKwon I checked every other built in function and this was the only one being used. What you think?

    Shall we change `dataset` to like .. `input_path` or `path`? I think the name `dataset` is usually used for `Dataset` instance.

    I think it's fine. It should better avoid shadowing builtin names but can you check out other examples too while we are here?

    Sure, and thanks for the review! I used the "dataset" name because I checked a few examples that also use it, but I'll rename to path then. I already checked all other examples using grep and this is the only one using "input" name.
