Can you test with string[pyarrow] here
There was a problem hiding this comment.
Sure things. It works fine so long as I make the comparison dataframe string[pyarrow] too of course:
StringIO(data),
header=None,
usecols=[0, 1],
dtype="string[pyarrow]",
dtype_backend="pyarrow",
engine="pyarrow",
)
expected = DataFrame([
["a", "i"], ["b", "j"]],
dtype="string[pyarrow]"
)
tm.assert_frame_equal(result, expected)
I'll update the PR with the change.
