针对您提出的“name 'x_train' is not defined”问题,这里有几个可能的解决方案和排查步骤,您可以根据这些建议来定位和解决问题: 检查变量名是否已正确定义: 确保在您的代码中已经定义了x_train变量。通常,这个变量是在数据预处理阶段从数据集中分割出来的训练数据。例如,使用sklearn.model_selection.train
svm.fit(X_train, y_train) y_pred = svm.predict(X_test) 在这个示例中,我们使用了鸢尾花数据集,并使用SVC算法进行分类。通过调用train_test_split函数,并将参数设置为70%训练集和30%测试集,我们成功划分了数据集。最后,我们对测试集进行前向传播和预测,得到了模型的性能指标。 总之,train_test_split函数是...
