module 'pandas' has no attribute 'indexes'

Hi I run into problems when I follow the example notebook .

The section on Grouped weighted calculations fails

calc.mean(grp_marriage_sex, "income").round().astype(int)

---

AttributeError Traceback (most recent call last)
in ()
----> 1 calc.mean(grp_marriage_sex, "income").round().astype(int)

P:\Anaconda3\envs\charite\lib\site-packages\weightedcalcs\core.py in func_wrapper(self, thing, *args, **kwargs)
20 agg = thing.apply(lambda x: func(self, x, *args, **kwargs))
21 is_series = isinstance(agg, pd.core.series.Series)
---> 22 has_multiindex = isinstance(agg.index, pd.indexes.multi.MultiIndex)
23 if is_series and has_multiindex:
24 return agg.unstack()

AttributeError: module 'pandas' has no attribute 'indexes

I am using pandas '0.20.1' and weightedcalcs '0.1.1'.

Thanks for flagging, @eotp! Looks like this error is being caused by something introduced to pandas between 0.19.0 and 0.20.1. I'll look into it.
