Before Change

After Change

    def set_grad(self, name: str, value: Array) -> None:
        Set a gradient value for the model.
        self._params.set_grad(self.id, name, value)

    def inc_grad(self, name: str, value: Array) -> None:
        Check whether the model has a gradient of the given name.
        self._params.inc_grad(self.id, name, value)
