我正在使用 timedeltas,似乎这段代码
copy_for_U.Time.astype('timedelta64[m]',copy=False);
不会更改数据框 - 如果我从文档中正确理解,它应该如此,它说:
Signature: full_df.Time.astype(dtype, copy=True, raise_on_error=True, **kwargs) Docstring: Cast object to input numpy.dtype Return a copy when copy = True (be really careful with this!)

例如,当我跑步jupyter-notebook

并pip install --upgrade pyzmq
没有解决问题
任何想法?
