column with dates into datetime index in dask

问题

pd.DatetimeIndex(df_dask_dataframe['name_col'])

I have a dask dataframe for which I want to convert a column with dates into datetime index. However I get a not implemented error. Is there a workaround?

回答1:

I think you need dask.dataframe.DataFrame.set_index if dtype of column is datetime64:

df_dask_dataframe = df_dask_dataframe.set_index('name_col')
