你的代码最后一行缺少右括号，修改后应该是这样的：

f1 = f1_score(y_pred, y_test, average='macro')     #模型评估准确性、精准度 # 假设 y_true 是真实标签，y_pred 是模型预测标签 
print('accuracy %s' % accuracy_score(y_pred, y_test)) 
print('precision %s' % precision_score(y_pred, y_test, average='weighted')) 
#print('recall %s' % recall_score(y_pred, y_test, average='weighted')) 
print('f1-score %s' % f1)
