>>> from pint.pandas_interface import PintArray
>>> import pandas as pd

>>> df = pd.DataFrame({"address": PintArray([1, 2, 3])})
>>> df
          address
0 1 dimensionless
1 2 dimensionless
2 3 dimensionless

>>> df.dtypes
address    Pint
dtype: object

>>> df['address']
0   1 dimensionless
1   2 dimensionless
2   3 dimensionless
Name: address, dtype: Pint

>>> df['address'].values.data
<Quantity([1 2 3], 'dimensionless')>

but unfortunately

>>> df['address'].values
<pint.pandas_interface.PintArray object at 0x117517f28>
