WebApr 12, 2024 · pth文件通常是用来保存PyTorch模型的参数,可以包含模型的权重、偏置、优化器状态等信息。而模型的架构信息通常包含在代码中,例如在PyTorch中,可以使用nn.Module类来定义模型的架构,将各个层组合在一起。 WebTorchvision has four variants of Densenet but here we only use Densenet-121. The output layer is a linear layer with 1024 input features: (classifier): Linear(in_features=1024, out_features=1000, bias=True) To reshape the network, we reinitialize the classifier’s linear layer as model.classifier = nn.Linear(1024, num_classes) Inception v3
