AttributeError: 'Series' object has no attribute 'ix'

在pandas版本0.20.0及其以后版本中，ix已经不被推荐使用，建议采用iloc和loc实现ix。

predictions_ARIMA_log = pd.Series(ts_log.ix[0],index=ts_log.index)
predictions_ARIMA_log = predictions_ARIMA_log.add(predictions_ARIMA_diff_cumsum,fill_value=0)
predictions_ARIMA_log.head()

Here is the error I am getting: 'Series' object has no attribute 'ix'

predictions_ARIMA_log = pd.Series(ts_log.iloc[0],index=ts_log.index)
predictions_ARIMA_log = predictions_ARIMA_log.add(predictions_ARIMA_diff_cumsum,fill_value=0)
predictions_ARIMA_log.head()
