선생님, '모의고사 풀어보기2' 를 시험환경에서 코딩을 하는데, 선생님께서 말씀해주신 lgb 를 사용하였는데, 없다는 에러가 나와서 문의드립니다.

[코딩내용]

import pandas as pd

pd.set_option('display.max_columns', None)

train = pd.read_csv('train.csv')

test = pd.read_csv('test.csv')

# print(train.shape, test.shape)

# print(train.head(3))

# print(test.head(3))

# print(train.info())

# print(train.describe())

# print(train.isnull().sum())

from sklearn.model_selection import train_test_split

X_tr, X_val, y_tr, y_val = train_test_split(train.drop('target', axis=1), train['target'], test_size=0.1, random_state=2022)

# print(X_tr.shape, X_val.shape, y_tr.shape, y_val.shape)

from sklearn.metrics import f1_score

import lightgbm as lgb

model = lgb.LGBMClassifier(random_state=2022)

model.fit(X_tr, y_tr)

pred = model.predict(X_val)

print(pred[:10])
