Dice loss

您好，我看到您多次提到LPCB这篇文章，这篇文章中提到他使用标准交叉熵训练HED得到了一个类似浮雕一样的结果图，但是我复现代码时得到的结果是一片空白，请问您有做过这个实验吗，这是什么原因呢？

Hello, I've seen you mention the LPCB article multiple times. In this article, it is mentioned that using standard cross-entropy to train HED produces a result similar to a relief sculpture. However, when I reproduced the code, I obtained a completely blank result. Have you conducted this experiment before? What could be the reason for this?
