torchvision上的 ResNet18 直接用于 cifar10 是不推荐的。需要做以下改动: 将conv1替换以支持 32×32 的输入。同时移除第一个maxpool避免图片信息过早丢失。 def init_model(): model = resnet18(weights=ResNet18_Weights.DEFAULT) model.conv1 = nn.Conv2d(model.conv1.in_channels, model.conv1.out_chan...

你可以试试下面的方法。这将适用于任何只改变偏移的图层。
(input = logits,target = labels_one_ hot, weight = weights) elif loss_type == "softmax" pred = logits.softmax(dim = 1) cb_ loss = F.binary_cross_entropy(input = pred, target = labels_one_ hot, weight = weights) return cb_ loss 第三步:训练 c fartra n.py import torch ...
