I am trying to drop the time portion on several pandas columns using the following code:
group_df['submitted_on'] = pd.DatetimeIndex(group_df['submitted_on']).to_period('d')
group_df['resolved_on'] = pd.DatetimeIndex(group_df['resolved_on']).to_period('d')
This works fine for the first column but I can't seem to figure out why I cant apply it ti multiple columns.
I am getting the following error attempting to execute the second line:
File "C:/Users/anshanno/PycharmProjects/RETIvizScript/RetiViz.py", line 271, in join_groups
group_df['resolved_on'] = pd.DatetimeIndex(group_df['resolved_on']).to_period('d')
File "C:\Python27\lib\site-packages\pandas\util\decorators.py", line 91, in wrapper

values, freq=freq, dayfirst=dayfirst, yearfirst=yearfirst)
File "pandas\tslib.pyx", line 2347, in pandas.tslib.parse_str_array_to_datetime (pandas\tslib.c:42450)
ValueError
Since the ValueError isn't telling me anything, I tried errors='coerce' without any luck - I still get the same undescriptive error.
group_df['resolved_on'] = pd.DatetimeIndex(group_df['resolved_on'], errors='coerce').to_period('d')
