パンダ。ミニバースライシング。エラー "pandas.tslib.OutOfBoundsDatetime"

Question

分を使用してパンダデータフレームをスライスし、エラーメッセージ "pandas.tslib.OutOfBoundsDatetime"を取得しようとしています。

私の理解では、私は、フォーマットXとパンダのデータをスライスできるということである[ 'HH：MM'： 'HH：MM']が、間違っているものを理解していない：

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

はbetween_time()メソッドを使用してみてください：

In [75]: x.between_time('04:01', '04:05') 
Out[75]: 
        0
