While this change correctly initializes aux_hidden_state_layers, it highlights a broader maintainability issue. The __init__ method of EagleMistralLarge3Model does not call super().__init__() from its base class DeepseekV2Model, but instead re-implements much of its logic. This is why aux_hidden_state_layers had to be added here manually after it was added to the base class.

To prevent similar issues in the future and to track this technical debt, I suggest adding a TODO comment. This will make it clear that a refactoring is needed to make the class more robust against changes in its parent.

        # TODO: Refactor to call super().__init__ from DeepseekV2Model
        # to avoid missing future attributes.
        self.aux_hidden_state_layers: tuple[int, ...] = ()

self.make_empty_intermediate_tensors = make_empty_intermediate_tensors_factory(
["hidden_states", "residual"], config.hidden_size
)
