当您在Python程序中遇到“name 'train_data' is not defined”的错误时,这通常意味着Python解释器在尝试访问train_data这个变量时,发现它并没有在当前的作用域内被定义。以下是一些可能的原因和相应的解决方法: 检查代码中是否定义了train_data变量: 确保您在代码中某个位置已经定义了train_data。例如: python tra...
y=data.data,data.target# 使用train_test_split函数划分数据集X_train,X_test,y_train,y_test=train_test_split(X,y,test_size=0.3,random_state=42)# 对训练集和测试集进行前向传播和预测fromsklearn.svmimportSVC
1. 检查代码中是否有定义`train_loader`这个变量的语句。如果没有，您需要先定义这个变量，可以使用`torch.utils.data.DataLoader`类来创建一个数据加载器。2. 如果有定义语句，检查是否在使用`train_loader`之前对其进行了初始化。如果没有，您需要在使用前对其进行初始化，可以使用`train_loader = Data...
