你好，我在对于DRIVE数据集上进行采样时，出现了这样问题，请问我该如何解决呢

我尝试打印他们的形状，分别为x_t: torch.Size([1, 1, 64, 64]),eps: torch.Size([1, 2, 64, 64])，然后我打印出eps中的数据，发现他的两个通道的数据是一样的，所以我将eps就只取了第一通道，就跑通了

I try to print their shapes, which are x_t: torch.Size([1, 1, 64, 64]), eps: torch.Size([1, 2, 64, 64]), and then I print out the Data, I found that the data of his two channels are the same, so I only took the first channel of eps, and it ran through.

But I still have my doubts about the cause of the problem.

How is your segmentation effect? After running this experiment, I feel that the segmentation results are not as good as UNet

My solution is the same as yours

但是我跑出的效果有点差

But the effect I ran out was a bit poor.

[2039551625]

请问你跑的数据集上的效果怎么样

What is the effect on the data set you ran?

My results were also very poor

兄弟，你大约训了多少步到达这个效果的？

Brother, how many steps have you trained to achieve this effect?

But the effect I ran was a bit bad
