绘制networkx图时出现意外错误

Question

我有一个简单的图形，需要在我的屏幕上绘制它，这是我的代码：

def gera_grafo(matriz):
grafo = nx.to_networkx_graph(matriz, create_using=nx.Graph)

nx.draw(grafo)
plt.show()

return grafo

其中矩阵是包含连接权重的邻接列表。coda 工作得很好，但我不得不创建一个新的 python virtualenv，从那时起，即使正确安装了所有必需的库，它也会在nx.draw()调用时引发错误。我得到的错误是：

    Traceback (most recent call last):
  File "/run/media/luisola/A216C03316C009ED/Users/Luis/Documents/Iniciação Científica/inicia-o-cient-fica/venv/lib/python3.9/site-packages/networkx/utils/decorators.py", line 396, in _random_state
    random_state_arg = args[random_state_index]
IndexError: tuple index out of range

The above exception was the direct cause of the following exception:

    raise nx.NetworkXError("random_state_index is incorrect") from e
networkx.exception.NetworkXError: random_state_index is incorrect

这是我的代码错误吗？如果是这样，我该怎么办？提前致谢

Answer 1

正如这个问题所述：networkx 显示 random_state_index 不正确 他们是decorator=5.0.0. 正如 GitHub 上的相关问题 ( https://github.com/networkx/networkx/issues/4718 ) 中所讨论的，decorator>=5.0.X 应该很快可用。因此，请稍等片刻升级或降级到旧版本，如上面 SO 问题中的建议。

编辑decorator==5.0.5 或 >=5.0.7 修复错误

正如上面链接的问题中所讨论的，装饰器现已更新和修复。

Answer 2

我正在使用decorator==5.0.6，并遇到了同样的错误。不过，升级到 5.0.7 解决了我的问题。
