在训练网络期间我的损失非常高

如何解决在训练网络期间我的损失非常高

请帮我解决这个问题。我的训练和验证损失都非常高。为什么会发生？代码如下：

kernels=[[4,3,2,1]]
out_channels=[[32,64,128,256]]
dropout_p=[[0.1,0.2,0.3,0.4,0.5,0.6]]
image_size=[224]
batch_size=[64]
n_epochs=500

for bs in batch_size:
  for k in kernels:
    for out_ch in out_channels:
      for dp in dropout_p:
        for img_s in image_size:
          print(f'batch_s:{bs} img_s:{img_s} kernels:{k} out_ch:{out_ch} dropout_p:{dp}')

          net=NaimishNet(img_s)
          init_weights(net.conv1)
          init_weights(net.conv2)
          init_weights(net.conv3)
          init_weights(net.conv4)
          init_weights(net.fc1)
          init_weights(net.fc2)
          init_weights(net.fc3)

          criterion=nn.MSELoss()
          optimizer=optim.Adam(params=net.parameters())

          plateau_lr_scheduler=lr_scheduler.ReduceLROnPlateau(optimizer,patience=7,verbose=True)

          train_loss,val_loss,epochs=train_net(net,n_epochs,img_s,bs,plateau_lr_scheduler)

这是我收到的平均训练和平均验证丢失通知。我试图改变学习率，应用批量归一化，...但没有奏效。
