错误(内核死亡,重新启动)使用pd.to_datetime,日期包含+01:00

时间:2017-07-17 19:34:04

标签: python pandas datetime

当使用此函数的日期包含tz差异后缀(例如2017-07-17T20:15:03.597144+01:00)时,核心在执行任何代码之前就会死亡。

如果删除+01:00,脚本将无错运行。

“Pendulum Timestamp”(pdts)的值为2017-07-17T20:19:14.508636+01:00

系统设置Windows 10 / Spyder 3.1.2 / Python 3.6 / Pandas 0.20.3。我尝试将Pandas更新为0.20.3,但核心仍然死亡。 这是RTFM还是一个bug?感谢

    import pendulum as pendulum
    import pandas   as pd

    pendulum_timestamp = pendulum.now() 

    pdts = pendulum_timestamp

    pen_timestamp = pd.to_datetime(pdts)

根据MaxU的要求输出“print(pd.show_versions())”

尝试将Pendulum对象强制转换为其字符串表示形式,因为pd.to_timestamp()并不期望Pendulum对象:

In [91]: import pendulum

In [92]: pdts = pendulum.now()

In [93]: type(pdts)
Out[93]: pendulum.pendulum.Pendulum

In [94]: pd.to_datetime(str(pdts))   # NOTE: pay attention at `str()`
Out[94]: Timestamp('2017-07-17 20:58:08.995228')

In [95]: pdts
Out[95]: <Pendulum [2017-07-17T22:58:08.995228+02:00]>

In [98]: str(pdts)
Out[98]: '2017-07-17T22:58:08.995228+02:00'

In [99]: type(str(pdts))
Out[99]: str
