'CountVectorizer' object has no attribute 'get_feature_names'

from TextFeatureSelection import TextFeatureSelection #Binary classification input_doc_list=new_df_4['txt'].values.tolist() target=new_df_4['target'].values.tolist() fsOBJ=TextFeatureSelection(target=target,input_doc_list=input_doc_list) result_df=fsOBJ.getScore() print(result_df)

That's my code and the error:

Please suggest the version on your computer for the scikit-learn library.

[primadermawan]

I got scikit-learn 1.2.2

some people suggest to change the get_feature_names into get_feature_names_out

[StatguyUser]

If you can deprecate scikit-learn and use older version it will work.

i try to calculate and use the library but the number of information gain value is so different, can you tell me how you implement the equation of information gain in your library?
