How to apply LabelEncoder for a specific column in Pandas dataframe
You can try as following:
le = preprocessing.LabelEncoder()df['label'] = le.fit_transform(df.label.values)
Or following would work too:
df['label'] = le.fit_transform(df['label'])
It will replace original label
values in dataframe with encoded labels.
You can also do:
from sklearn.preprocessing import LabelEncoderle = LabelEncoder()df.col_name= le.fit_transform(df.col_name.values)
where col_name = the feature that you want to label encode
from sklearn.preprocessing import LabelEncoder le = LabelEncoder() X[:, 2] = le.fit_transform(X[:, 2])
this could be helpful if you want to change the particular column in your CSV data
