我们将训练一个epoch(尽管可以随意增加num_epochs),将我们的网络暴露给每个数据样本一次。 num_epochs = 1 loss_hist = [] test_loss_hist = [] counter = 0 # Outer training loop for epoch in range(num_epochs): iter_counter = 0 train_batch = iter(train_loader) # Minibatch training loop for...
for epoch in range(num_epochs): model.train() # 将模型设置为训练模式,启用诸如Dropout和BatchNorm等层的功能 train_loss = 0.0 # 记录训练集的累计损失 train_acc = 0.0 # 记录训练集的累计准确率 for i, (inputs, labels) in enumerate(train_loader): # 遍历训练集的每个批次 optimizer.zero_grad(...

For example 0.9 != 2 and you can never predict class 2, but you might, by accident, predict class 1 (0.999999999 ~= 1). This function should be called within your inner loop, just like you calculate loss, so it would be: for epoch in range(epochs): running_loss = 0.00 running_acc...
