有关nn.Modules参数的一些注意事项。当检查由几个子模块组成的模型的参数时,能够通过名称识别参数是很方便的。有一个方法可以做到这一点,称为named_parameters: # In[18]:forname, paraminseq_model.named_parameters():print(name, param.shape)# Out[18]:0.weight torch.Size([13,1])0.bias torch.Size(...
model.state_dict():返回一个OrderedDict对象,一般用于模型的保存 model.parameters():返回一个生成器(generator,即用yield返回),只包含了层的权重,一般用于优化器的初始化 model.named_parameters():返回一个生成器,其中包含了层的名称以及层的权重 importtorchfromtorchimportnn ...

optimizer = optim.SGD(model.parameters(),lr =0.005, momentum =0.9) 仅仅需要 5 个 epoch(一个 epoch 意味着你使用整个训练数据集来更新训练模型的权重),我们就可以训练出一个相当准确的 LeNet 模型。这段代码检查可以确定文件中是否已有预训练好的模型。有则加载;无则训练一个并保存至磁盘。
