Problems during sample

[ValeriaLiu]

I run the segmentation_sample.py, and meet the problem:

I know that it is because x_start.shape is not equal to x_t.shape. However, My dataset is similar to ISICDataset, so I feel very strange.
Thanks a lot if you can reply.

Have you solved it? I have the same doubt, thanks!

Have you figure it out? I have the same question...

[WuJunde]

could you print x_start.shape and x_t.shape?

[jojo803]

I try to print x_start.shape and x_t.shape however there is an error occurred before I can get x_start.

I print x_t.shape and eps.shape, and result is like this:
x_t.shape= torch.Size([1, 1, 64, 64])
eps.shape= torch.Size([1, 2, 64, 64])

I suppose to use the right dataset step by step in Readme.md. The eps[:, 0, :, :] is totally the same as eps[:, 1; :, :]. After clipping eps to [1,1,64,64] by deleting either of them, program can work. I can't understand why their shapes are not consistant. Therefore, I can't figure out whether I can get the right answer by simple clipping conducted by myself without theory support.

Hello! I have encountered a type-related issue with the ISIC dataset. Specifically, I'm getting the following error:

"assert x_t.shape == eps.shape
AssertionError"

Could you please help me identify which line of code needs to be modified to make the project run successfully?

[zzh1230]

Has it been resolved? I encountered the same problem

[chenyu1330]

Why is it that the result of my last training in BraTS is a MRI diagram?
