'Index' object has no attribute 'tzinfo'

[h4nz11]

Hello,
I've tried to update pandas to the latest version and make this query
SELECT mean(value) FROM data WHERE time >= '2018-10-01' AND time < '2019-02-01' GROUP BY time(1d) tz('Europe/Prague')
but if I hit time period withnout any data, I will get this error

influxdb/_dataframe_client.pyc in _to_dataframe(self, rs, dropna)
    203             df.time = pd.to_datetime(df.time)
    204             df.set_index('time', inplace=True)
--> 205             if df.index.tzinfo is None:
    206                 df.index = df.index.tz_localize('UTC')
    207             df.index.name = None

AttributeError: 'Index' object has no attribute 'tzinfo'

I am having the same issue too.

Any solution to this issue?

I have pandas pinned to version < 0.24

We run into the same issue and I can confirm that by setting pandas < 0.24 we could resolve it (or by leaving tz('Europe/Prague') away or extending the query with epoch="ns" (see: #676 (comment)) but that is probably not what one wants to do).

Could you please fix this issue for the latest pandas release? At the moment, it is no possible to use google colab with influxdb due to this problem.
