Quickstart > Charting > hourly throws TypeError: datetime64 type does not support sum operations

https://nem-reader.readthedocs.io/en/latest/quickstart.html hourly = df.groupby([(df.index.hour)]).sum()

TypeError: datetime64 type does not support sum operations

Workaround: https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.sum.html hourly = df.groupby([(df.index.hour)]).sum(numeric_only=True)

I'm clueless about dataframes and pandas, so hopefully that is the right answer.
