How can I solve this error?: networkx.exception.NetworkXError: ('Adjacency matrix is not square.', 'nx,ny=(10, 11)')

Question

我正在尝试使用 networkx 从 numpy 数组创建图表，但出现此错误：networkx.exception.NetworkXError: ('Adjacency matrix is not square.', 'nx,ny=(10, 11)') 有人知道怎么解决吗？

for k,v in My_Diz.items():
    G = nx.from_numpy_matrix(v)
    nx.draw(G)

Answer 1

你的矩阵不是正方形的。你必须给 networkx 一个方阵。由于矩阵是 (n × n+1)，并且是三角形的，你可以这样做：

for k,v in My_Diz.items():
  r, c = v.shape
  M = np.zeros((c,c))
  M[:r, :c] = v
  M[:c, :r] += v.T
  G = nx.from_numpy_matrix(M)
  nx.draw(G)
