import seaborn as sns

import matplotlib.pyplot as plt

sns.regplot(x = df['1stFlrSF'][:train_num], y=train_Y)

# 做線性迴歸, 觀察分數

train_X = MMEncoder.fit_transform(df)

estimator = LinearRegression()

cross_val_score(estimator, train_X, train_Y, cv=5).mean()

TypeError: Cannot cast array data from dtype('int64') to dtype('int32') according to the rule 'safe'

附上程式碼, 出現如上Error, 求解!
