Description
Hi!
When I create a pandas interval series and then convert it into a pyarrow array and then try to convert that pyarrow array back to pandas I'm getting an attribute error. The error says that Series object has no attribute `to_pandas`.
I've added the code that produces the error below.
// code placeholder In [14]: x = pd.Series([pd.Interval(0, 1), pd.Interval(2, 3), pd.Interval(3, 4)]) In [15]: y = pa.Array.from_pandas(x) In [16]: y.type Out[17]: ArrowIntervalType(extension<pandas.interval>) In [17]: y.to_pandas() --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-17-48c5b189df56> in <module> ----> 1 y.to_pandas()~/compose/etc/conda/cuda_10.2/envs/rapids/lib/python3.7/site-packages/pyarrow/array.pxi in pyarrow.lib._PandasConvertible.to_pandas()~/compose/etc/conda/cuda_10.2/envs/rapids/lib/python3.7/site-packages/pyarrow/array.pxi in pyarrow.lib.ExtensionArray._to_pandas()~/compose/etc/conda/cuda_10.2/envs/rapids/lib/python3.7/site-packages/pandas/core/generic.py in __getattr__(self, name) 5128 if self._info_axis._can_hold_identifiers_and_holds_name(name): 5129 return self[name] -> 5130 return object.__getattribute__(self, name) 5131 5132 def __setattr__(self, name: str, value) -> None:AttributeError: 'Series' object has no attribute 'to_pandas'
It would be great tp have a method to convert from a pyarrow interval array directly into a pandas series.
