Python/iPython을 사용한 네트워크 플롯 오류

Question

IPXML 노트북에서 OSX 10.8.2에서 networkx를 사용하려고하면 다음 시작 코드 오류가 발생합니다 (AttributeError : 인접하지 않은 배열의 호환되지 않는 모양).

import networkx as nx 
g = nx.Graph() 
g.add_node(1) 
g.add_node(2) 
g.add_edge(1,2) # no error if this line is omitted 
nx.draw(g) 

이 그래프에 가장자리를 추가하지 않으면 오류가 표시되지 않습니다. Matplotlib, Numpy 및 Scipy는 모두 here으로 제안되었습니다.
