object for any subgraph can be retrieved by calling
      graph_info.find_partition(id).
  Example:

     ==================================== Tree: =====================================
     5 X   __2 X    __1 â
     id:  |  id: 0 |  id: 00
          |        |
          |        |__1 X (aten::relu)
          |           id: 01
          |
          |__3 X    __1 â
             id: 1 |  id: 10
                   |
                   |__2 X     __1 X (aten::relu)
                      id: 11 |  id: 110
                             |
                             |__1 â
                                id: 111
     =========================== Mismatch leaf subgraphs: ===========================
     ['01', '110']
     ============================= Mismatch node kinds: =============================
     {'aten::relu': 2}
