設置時區爲熊貓數據幀

嗨我試圖將時區設置爲數據幀，然後將其更改爲UCT時區。設置時區爲熊貓數據幀

我讀的數據是：

Date Time;G_h 
2012-03-31 23:00:00.000;0 
2012-03-31 23:15:00.000;0 
2012-03-31 23:30:00.000;0 
2012-03-31 23:45:00.000;0 
2012-04-01 00:00:00.000;0 
2012-04-01 00:15:00.000;0 
2012-04-01 00:30:00.000;0 
2012-04-01 00:45:00.000;0 
2012-04-01 01:00:00.000;0 
2012-04-01 01:15:00.000;0 
2012-04-01 01:30:00.000;0

我使用此代碼

df = pd.read_csv('input.csv', sep=";", index_col='Date Time', decimal=',') 
df.index = pd.to_datetime(df.index, unit='s')

我的想法是使用此代碼：如果我嘗試

df.index.tz_localize('Europe/Rome').tz_covert('UTC')

用此代碼設置時區'Europe/Rome'

df.index=df.index.tz_localize('Europe/Rome')

我得到這樣的結果：

Traceback (most recent call last): 
    File "/usr/lib/python2.7/dist-packages/IPython/core/interactiveshell.py", line 2820, in run_code 
    exec code_obj in self.user_global_ns, self.user_ns 
    File "<ipython-input-38-0aa69957bc90>", line 1, in <module> 
    d.index.tz_localize('Europe/Rome') 
    File "/usr/local/lib/python2.7/dist-packages/pandas/tseries/index.py", line 1608, in tz_localize 
    new_dates = tslib.tz_localize_to_utc(self.asi8, tz, infer_dst=infer_dst) 
    File "tslib.pyx", line 1981, in pandas.tslib.tz_localize_to_utc (pandas/tslib.c:29912) 
AmbiguousTimeError: Cannot infer dst time from Timestamp('2012-10-28 02:00:00', tz=None), try using the 'infer_dst' argument

什麼建議嗎？

我確定輸入文件中的時間設置正確，dst正常！

試試這個：

from __future__ import print_function 

import pytz 
import pandas as pd 

from_tz = pytz.timezone('Europe/Rome') 
to_tz = pytz.timezone('UTC') 

df = pd.read_csv('input.csv', sep=";", index_col='Date Time', decimal=',') 
df.index = pd.to_datetime(df.index, unit='s').tz_localize(from_tz).tz_convert(to_tz) 

print(df)

輸出：

      G_h 
Date Time 
2012-03-31 21:00:00+00:00 0 
2012-03-31 21:15:00+00:00 0 
2012-03-31 21:30:00+00:00 0 
2012-03-31 21:45:00+00:00 0 
2012-03-31 22:00:00+00:00 0 
2012-03-31 22:15:00+00:00 0 
2012-03-31 22:30:00+00:00 0

2012-03-31 23:00:00+00:00 0 
2012-03-31 23:15:00+00:00 0 
2012-03-31 23:30:00+00:00 0
