如何生成datetime64[ns, UTC] numpy系列?

Question

我正在尝试生成类型为datetime64[ns, UTC]的numpy系列，但没有成功。

这是我尝试过的:

test = np.array(np.datetime64('2005-01-03 14:30:00.000000000'))
test
>array('2005-01-03T14:30:00.000000000', dtype='datetime64[ns]')

和转换，没有成功:

test = np.array(np.datetime64('2005-01-03 14:30:00.000000000').tz_localize('UTC'))
test
>>>
---------------------------------------------------------------------------

----> 1 test = np.array(np.datetime64('2005-01-03 14:30:00.000000000').tz_localize('UTC'))
2 test
AttributeError: 'numpy.datetime64' object has no attribute 'tz_localize'

Answer 1

我能够达到这个结果:

0   2005-01-03 14:30:00+00:00
dtype: datetime64[ns, UTC]

使用下面的代码:

import numpy as np
import pandas as pd
s = pd.Series(np.datetime64('2005-01-03 14:30:00.000000000'))
s.dt.tz_localize('UTC')
