import torch 从PyTorch库中导入nn模块: nn模块包含了构建神经网络所需的所有基本构建块,如层、激活函数等。 python from torch import nn 定义一个名为LeNet的类,该类继承自nn.Module: nn.Module是PyTorch中所有神经网络模块的基类。通过继承这个类,我们可以定义自己的神经网络模型。 python class LeNet(nn.Mo...

在PyTorch 中,通常我们会将模型定义为一个继承自torch.nn.Module的类。一个典型的模型结构如下: importtorchimporttorch.nnasnnclassMyModel(nn.Module):def__init__(self):super(MyModel,self).__init__()self.fc=nn.Linear(10,2)defforward(self,x):returnself.fc(x) ...
