to_csv錯誤與熊貓數據幀與時區

下面的代碼給出了熊貓0.17下的錯誤，但與0.16.2工作得很好。to_csv錯誤與熊貓數據幀與時區

to_pickle函數沒有問題，但在to_csv時出錯。

有人給我提個建議嗎？

In[23]: new_index = pd.date_range('2015-01-01', '2015-12-31', freq = 'H', tz='Europe/Paris') 
In[24]: df = pd.DataFrame({}, index = new_index) 
In[25]: df['test'] = 1. 
In[26]: df.to_pickle(r'test.h5') 

In[27]: df.to_csv(r'test.csv')

這似乎是一個已知的錯誤#11619，並將其固定在0.17.1

根本的問題是，你的時間內從標準時間跨越到夏令時，這是表示確切時間錯誤AmbiguousTimeError: Cannot infer dst time from Timestamp('2015-10-25 02:00:00')
