在resampleDataFrame上使用panda 函数以将tick数据转换为OHLCV时,会遇到重采样错误.

我们该如何解决错误？

data = pd.read_csv('tickdata.csv', header=None, names=['Timestamp','Price','Volume']).set_index('Timestamp')
data.head()

# Resample data into 30min bins
ticks = data.ix[:, ['Price', 'Volume']]
bars = ticks.Price.resample('30min', how='ohlc')
volumes = ticks.Volume.resample('30min', how='sum')

这给出了错误:

TypeError: Only valid with DatetimeIndex or PeriodIndex
