Thank you very much!I preprocessed the images before sending to the network.Please see the attachment.

Are they 2D - not sure the code can handle 2D images although the change should be minimal. Also, when you say not decreasing is it diverging or just not changing at all?, the latter probably means some error.

我重写了网络部分的代码,也修改了多尺度Dice的函数(把3D卷积改成2D,还有修改维度,其它没做改变),来适应二维图像。在网络训练过程中,loss初始为0.5左右,之后一直在0.480~0.50间来回浮动,尝试过调整学习率以及loss的scale,都没有用。

@yunzhen we have done the same for 2d images and it should work. Your problem should be general debugging/tuning problem. I'd suggest start with simple toy examples first to debug your own code.

I'm closing this now, but feel free to raise a new one if other specific problems.
