在 python 中是否有理由在 class 中将 self 传递给 static 方法？

Question

I was reviewing code at One-Class Neural Network .

The author creates a @staticmethod :

@staticmethod
def custom_ocnn_loss(self,nu, w, V):

but later inside the OC_NN fit instance method, accesses it using the class name and passes in self :

model.compile(loss=OC_NN.custom_ocnn_loss(self,nu, w, V), optimizer=opt,metrics=None)

Is there a reason to do this (ie create @staticmethod which takes self as an argument and is accessed inside instance method using class name)?

Answer 1

In the script, custom_ocnn_loss function has @staticmethod decorator which means it is not an instance method but a static method. The variable self might suggest differently, but when calling the custom_ocnn_loss function, the self variable is passed to it.
