Fill with the most frequently occurring value of a series
for name,sub_group in op_train.groupby('UID'):
if sub_group['geo_code'].value_counts().isnull().any():
sub_group['geo_code'].fillna(-1,inplace=True)
else: sub_group['geo_code'].fillna(sub_group['geo_code'].value_counts[:1],inplace=True)
I want to group by username, then count the geo_code attribute of the username. If it is empty, then fill the attribute with -1, otherwise it will be filled with the most frequently occurring value of this column, but I found that there is no effect after doing this. I don’t know why.
Besides, if I replace value_counts[:1] with index[0], it will return an error that IndexError: index 0 is out of bounds for axis 0 with size 0. Can anyone help me ?
