Pandas. Minute Bar Slicing. Ошибка «pandas.tslib.OutOfBoundsDatetime»

Question

Попытка среза Panda Dataframe с использованием минут и получение сообщения об ошибке «pandas.tslib.OutOfBoundsDatetime».

Я понимаю, что я могу порезать данные панды с форматом х [ «HH: MM»: «HH: MM»], но не понимаю, что это неправильно:

min_index 
Out[237]: 
0 04:00 
1 04:01 
2 04:04 
3 04:05 
4 04:07 
    dtype: object 

df=pd.DataFrame(np.arange(5)) 

x=df.set_index(pd.to_datetime(min_index)) 

x

Answer 1

Попробуйте использовать between_time() метод:

In [75]: x.between_time('04:01', '04:05') 
Out[75]:
