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, 1, 16, 64, 64]) torch.Size([2, 16, 64, 64])

这个报错大部分原因是index越界了。你也可以检查一下你的数据的shape，有些ct数据会多一个维度

您好，请问这个问题您解决了吗？
