The difference of soft_cls_cost in dsl assigner between mmyolo and mmdetection

[zuoheng199247]

I found it is very different that the code for soft_cls_cost in dsl assigner between mmyolo and mmdetection.
我发现在mmyolo和mmdetection工程里面dsl配备器的cls_cost计算代码有很大不同。
mmyolo:

mmdetection:

I think the code in mmdetection is same to the manual of mmyolo RTMdet： https://mmyolo.readthedocs.io/zh-cn/latest/recommended_topics/algorithm_descriptions/rtmdet_description.html#id6
我认为mmdetection里面的代码和mmyolo RTMdet手册里面的描述是一致的。

However, I can't understand the code in mmyolo, and I think the results of two codes might be not equal.
但是，我无法理解mmyolo工程里面的代码，并且我认为这两种写法的结果应该是不等价的。

Could anyone tell me the reason?
有谁可以告诉我一下原因吗？
