Mode Function Description
Training
... outputs = model(images) 输入图像和标签,通过infer计算得到预测值
... loss = criterion(outputs, target) 计算损失函数
... optimizer.zero_grad() 清空过往梯度
... loss.backward() 反向传播,计算当前梯度
... optimizer.step() 根据梯度更新网络参数
... scheduler.step() Learning Rate Scheduler
Validation
... with torch.no_grad() Validation Mode
... outputs = model(images) 输入测试图像和标签,通过infer计算得到预测值
... loss = criterion(outputs, target) 计算损失函数
