Question

试图绘制类似树的分层结构，但是当分支导致公共输出时会出错。

在绘制具有不同输出的层次树时没有出现错误，但是当公共输出时发生错误。

def Create_Hierarchy(chunks):
    G = nx.Graph()
    G.add_edges_from(chunks)
    pos = _hierarchy_pos(G, root='A', width=0.07, vert_gap=0.02, vert_loc=0.09, xcenter=0.50)    
    nx.draw(G, pos, arrows=True, with_labels=True)
    plt.subplots_adjust(top=0.9, wspace=4.0, hspace=2.99)
    plt.savefig('D:\\Hierarchy'+timestr+'.png')
    plt.show()
    # return rootTree
print(Create_Hierarchy(chunks=[('A','B'), ('A','C'), ('A','D'), ('A','E'), ('A','F'), (**'B','G'**), (**'C','G'**), ('D','I'), ('E','J'), ('F','K')]))

错误：

  File "D:\Selenium Workspace\PyDemoProject\src\Tree.py", line 67, in _hierarchy_pos
    pos = _hierarchy_pos(G, child, width=dx, vert_gap=vert_gap, vert_loc=vert_loc-vert_gap, xcenter=nextx, pos=pos, parent=root)
  File "D:\Selenium Workspace\PyDemoProject\src\Tree.py", line 67, in _hierarchy_pos
    pos = _hierarchy_pos(G, child, width=dx, vert_gap=vert_gap, vert_loc=vert_loc-vert_gap, xcenter=nextx, pos=pos, parent=root)
  File "D:\Selenium Workspace\PyDemoProject\src\Tree.py", line 67, in _hierarchy_pos
    pos = _hierarchy_pos(G, child, width=dx, vert_gap=vert_gap, vert_loc=vert_loc-vert_gap, xcenter=nextx, pos=pos, parent=root)
  [Previous line repeated 995 more times]
  File "D:\Selenium Workspace\PyDemoProject\src\Tree.py", line 59, in _hierarchy_pos
    children = list(G.neighbors(root))
  File "C:\Users\VG-11\AppData\Roaming\Python\Python37\site-packages\networkx\classes\graph.py", line 1266, in neighbors
    return iter(self._adj[n])

出现RecursionError：调用Python对象时超出了最大递归深度
