预测值:pred
真实值:y_test

直接用平均值
mean(pred == y_test)

准确得分
from sklearn.metrics import accuracy_score
accuracy_score(pred, y_test)
accuracy_score(pred, y_test, normalize=False)

混淆矩阵
from sklearn.metrics import confusion_matrix
confusion_matrix(pred, y_test)


汉明
from sklearn.metrics import hamming_loss
hamming_loss(pred, y_test)
