python-3.x - 'str'对象没有'decode'属性，我用Python中的sklearn做机器学习

Question

我不知道为什么 python 3 内核告诉我 'str' 对象没有属性 'decode'

from sklearn.datasets import load_digits

X_digits,y_digits = load_digits(return_X_y = True)

from sklearn.model_selection import train_test_split

X_train,X_test,y_train,y_test = train_test_split(X_digits,y_digits,random_state=42)
y_train.shape
from sklearn.linear_model import LogisticRegression
n_labeled = 50

log_reg = LogisticRegression(random_state=42)
log_reg.fit(X_train[:n_labeled], y_train[:n_labeled])
log_reg.score(X_test, y_test)
