2유형 랜덤포레스트 회귀 작업중 워닝 메시지

데이터 결측치 전처리 하는데

이렇게 코드 작업을 했더니 워닝 메시지가 뜨는데

시험환경에서도 수정이 필요할까요?

# 데이터 전처리 _ 결측치 대체 df['fuel_type'].fillna(df['fuel_type'].mode()[0], inplace = True) df['accident'].fillna(df['accident'].mode()[0], inplace = True) df['clean_title'].fillna(df['clean_title'].mode()[0], inplace = True)

<ipython-input-37-b2145d16d236>:15: FutureWarning: A value is trying to be set on a copy of a DataFrame or Series through chained assignment using an inplace method. The behavior will change in pandas 3.0. This inplace method will never work because the intermediate object on which we are setting values always behaves as a copy. For example, when doing 'df[col].method(value, inplace=True)', try using 'df.method({col: value}, inplace=True)' or df[col] = df[col].method(value) instead, to perform the operation inplace on the original object. df['fuel_type'].fillna(df['fuel_type'].mode()[0], inplace = True)
