超级成就了什么

Question

这是用于构建自定义keras层的代码

class MyLayer(Layer):

    def __init__(self, output_dim, **kwargs):
        self.output_dim = output_dim
        super(MyLayer, self).__init__(**kwargs)

超级在这里做什么，这绝对必要吗？ 我不明白什么是继承

Answer 1

欢迎来到stackoverflow。超级-

“.. returns a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class. The search order is same as that used by getattr() except that the type itself is skipped.”

特别是在Keras的情况下，基本层执行该类的所有基本操作，如源代码中一样，
