如何将numpy.datetime64对象转换为datetime.datetime(或Timestamp)？

在以下代码中,我创建了datetime,timestamp和datetime64对象.

import datetime
import numpy as np
import pandas as pd
dt = datetime.datetime(2012, 5, 1)
# A strange way to extract a Timestamp object, there's surely a better way?
ts = pd.DatetimeIndex([dt])[0]
dt64 = np.datetime64(dt)

In [7]: dt
Out[7]: datetime.datetime(2012, 5, 1, 0, 0)

In [8]: ts
Out[8]: <Timestamp: 2012-05-01 00:00:00>

In [9]: dt64
Out[9]: numpy.datetime64('2012-05-01T01:00:00.000000+0100')

注意:从时间戳中获取日期时间很容易:

In [10]: ts.to_datetime()
Out[10]: datetime.datetime(2012, 5, 1, 0, 0)

但是我们如何从()中提取datetime或者？Timestampnumpy.datetime64dt64 …
