draw_graphviz在哪？

Question

我刚开始编程，正在尝试阅读这本书："Natural Language Processing with Python (2009)“，但是我似乎找不到解决这个错误的方法。我想这个graph_viz问题以前已经讨论过了，但我也意识到语法规则可能会改变。它应该显示一个看起来很酷的可视化效果。这是模块问题还是语法问题？

import networkx as nx
import matplotlib
from nltk.corpus import wordnet as wn
def traverse(graph, start, node): 
    graph.depth[node.name] =
node.shortest_path_distance(start)
        graph.add_edge(node.name, child.name)
        traverse(graph, start, child)

def hyponym_graph(start):
    G = nx.Graph()
    G.depth = {}
    traverse(G, start, start)
    return G

def graph_draw(graph):
    nx.draw_graphviz(graph,
        node_size = [16 * graph.degree(n) for n in graph],
        node_color = [graph.depth[n] for n in graoh],
        with_labels = False)
matplotlib.pyplot.show()

dog = wn.synset('dog.n.01')
graph = hyponym_graph(dog)
graph_draw(graph)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in graph_draw
AttributeError: module 'networkx' has no attribute 'draw_graphviz'

它似乎已经在2.0版中被删除，以修复一个错误。更改备注为here
