# multiple labels
pmidx = pd.MultiIndex.from_arrays(arrays, names=[("zero", "first"), ("one",
"second")])
psmidx = ps.from_pandas(pmidx)
psmidx.dtypes.index
Out[6]:
MultiIndex([('zero', 'first'),
( 'one', 'second')],
)
pmidx.dtypes.index
Out[7]: Index([('zero', 'first'), ('one', 'second')], dtype='object')
pd.__version__
Out[8]: '1.4.2'
```
cc @xinrong-databricks index.dtype index mismatch.
But I just rethink it might be an unexpected change on Pandas. I rasie the
issue here: https://github.com/pandas-dev/pandas/issues/46900
