python not found in axis_fbprophet报错：KeyError: ‘[] not found in axis’

近日在尝试使用fbprophet算法替换原来的ARIMA做时序预测，安装过程中踩过的坑先不提(后面有时间会另起一篇说明)，此处单说一个很莫名其妙的问题。

在跑官方示例的时候：

import pandas as pd

import numpy as np

from fbprophet import Prophet

import matplotlib.pyplot as plt

df = pd.read_excel('example_wp_peyton_manning.xlsx')

df['y'] = np.log(df['y'])

playoffs = pd.DataFrame({

'holiday': 'playoff',

'ds': pd.to_datetime(['2008-01-13', '2009-01-03', '2010-01-16',

'2010-01-24', '2010-02-07', '2011-01-08',

'2013-01-12', '2014-01-12', '2014-01-19',

'2014-02-02', '2015-01-11', '2016-01-17',

'2016-01-24', '2016-02-07']),

'lower_window': 0,

'upper_window': 1,

})
