将Dask列转换为类型为datetime的新的Dask列 [英] Converting a Dask column into new Dask column of type datetime

问题描述

我在dask数据框(df)中有一个未分析的列，我正在使用pandas转换为datetime并将其放入dask数据框的新列中.但是由于列分配不支持DatetimeIndex类型而中断.

I have an unparsed column in a dask dataframe (df) that I am using pandas to convert to datetime and put into a new column in the dask dataframe. However it breaks as column assignment doesn't support type DatetimeIndex.

df['New Column'] = pd.to_datetime(np.array(df.index.values), format='%Y/%m/%d %H:%M')

推荐答案

这应该有效

import dask.dataframe as dd
# note df is a dask dataframe 
df['New Column'] = dd.to_datetime(df.index, format='%Y/%m/%d %H:%M')
