test预测不出来结果

您好，最近在用您分享的代码做分割，train的背景dice0=0.9984,目标dice1= 0.6014，但是test的时候dice0=0.6787,dice1=0.0011，且预测出来的标签全黑。我是用4个GPU进行训练和预测的，请问出现这种问题的原因是什么呢？和模型参数的读取有关系？希望得到您的帮助！

请问为什么3D UNet结构里没有用normalization？

您好~如题，我注意到[Unet.py](https://github.com/lee-zq/3DUNet-Pytorch/blob/master/models/UNet.py)里似乎没有涉及到任何比如batch或者instance等等的normalization操作，但我记得原始的3D UNet里应该是有的。请问您这样做是有什么用意吗？还是说encoder某一步里有自带normalization呢？盼复，十分感谢！

RuntimeError: Invalid index in scatter

你好，我用你的网盘数据可以训练测试，但是用我自己的CT数据、分割数据，到这一步就卡住报错了： fixd_path = r'D:\Download\3DUNet-Pytorch-master\fixed_data' dataset = Lits_DataSet([16, 64, 64],0.5,fixd_path,mode='train') #batch size data_loader=DataLoader(dataset=dataset,batch_size=2,num_workers=1, shuffle=True) for batch_idx, (data, target) in enumerate(data_loader): print("最大值：") print(torch.max(target.long() , 0)) print(data.shape, target.shape) target = to_one_hot_3d(target.long()) 到to_one_hot_3d()函数里的scatter时报错 torch.Size([2,...
