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_test_spl...
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...
train_test_split函数位于sklearn.model_selection模块中,它的主要作用是将数据集划分为训练集和测试集。因此,在使用train_test_split函数之前,我们必须确保已正确地导入了它。 下面是一个简单的示例,展示了如何正确导入并使用train_test_split函数: from sklearn.model_selection import train_test_split 有了这个导入...
