(self, a, axis=None, out=None, keepdims=True)
return OpTreeNode.build("sum", a, None, axis=axis, out=out)
Calculates the summation of the elements along the specified axis.

        Arguments:
            a (Tensor): the Tensor on which to perform the sum
            axis (int, optional): the dimension along which to compute.
                                  If set to None, we will sum over all
                                  dimensions.
            out (Tensor, optional): where the result will be stored. If out is
                                    None, only the op-tree will be returned.
            keepdims (bool, optional): Keep the axes being computed over in the
                                       output (with size 1), instead of
                                       collapsing.  Defaults to True.

        Returns:
            OpTreeNode: the resulting op-tree
