Hey, If you have a problem with this function you can fix it like this code: ` def draw_graph(G, show_names=False, node_size=1, font_size=10, edge_width=0.5):

adjacency = nx.adjacency_matrix(G)

adjacency = csr_matrix(adjacency)

names = np.array(list(G.nodes())) 
graph = Bunch(adjacency=adjacency, names=names) 

pagerank = PageRank() 
pagerank.fit(adjacency)  # Compute PageRank scores

scores = pagerank.scores_

if show_names: 
    names = [str(name) for name in graph.names]  
    image = svg_graph(graph.adjacency, font_size=font_size, node_size=node_size, names=names, width=700, height=500, scores=scores, edge_width=edge_width) 
else: 
    image = svg_graph(graph.adjacency, node_size=node_size, width=700, height=500, scores=scores, edge_width=edge_width) 

return SVG(image)
