まだスケール変換をする前ですが、エラーが出る意味がわかりません。

from sklearn.datasets import load_wine
from sklearn.svm import SVC
import numpy as np
from sklearn.model_selection import train_test_split

wine = load_wine()

X_train, X_test, y_train, y_test = \
    train_test_split(wine.data, wine.target, stratify=wine.target, 
random_state=42)
svc = SVC()
svc.fit(X_train, y_train)
print(svc.score(X_train, y_train))
print(svc.score(X_test, y_test))

何度やってもこのようなエラーが出てしまいます。どなたかわかる方お願いします。
