AttributeError:输入对象“图”没有属性“edges_list”

Question

我试着用OOP创建一个图形。我得到一个错误的AttributeError: type object 'Graph' has no attribute 'edges_list'，我不明白为什么。下面是代码:我希望得到一些帮助。我确实设置了一个名为edges_list的图的属性。为什么它找不到？

import numpy as np
import networkx as nx

class Graph:
    def __init__(self, edges_file):
        self.node_set = set() #Set of nodes by name
        self.edges_list = []
        self.edges_file = edges_file
        self.generate_graph(edges_file)


    class Node:
        def __init__(self, name):
            self.name = name
            self.metal = -1

    class Edge:
        def __init__(self, name):
            self.name = name
            self.side1 = 0
            self.side2 = 0
            self.resistance = 0

    def generate_graph(self, edges_file):
        G = nx.Graph()
        G.add_nodes_from(range(0,856284))
        nodes_file = open('nodes.csv','r') 
        nodes_file_content = nodes_file.readlines()
        with open('edges.csv', 'r') as edges_file:
            next(edges_file)
            for line in edges_file:
                splitted_line = line.split(",")
                edge_name = splitted_line[0]
                node_name = splitted_line[1]
                neighbor_name = splitted_line[2]
                new_edge = self.Edge(edge_name)
                new_edge.side1 = splitted_line[1]
                new_edge.side2 = splitted_line[2]
                self.edges_list.append(new_edge.name)
                self.node_set.add(self.Node(node_name).name)
                self.node_set.add(self.Node(neighbor_name).name)
        edges_file.close()
        nodes_file.close()

if __name__ == '__main__':
    graph = Graph('edges.csv')
    Graph.generate_graph(Graph,'edges.csv')

Answer 1

如果您添加了edges.csv和nodes.csv文件，这将是有帮助的。如果没有它，它更像是一个疯狂的建议，看起来其中一个问题出现在您的第二行：Graph.generate_graph(Graph,'edges.csv')

相反，尝试使用：graph.generate_graph(r'.\edges.csv')运行代码

另外，在def generate_graph中，这一行是错误的：

with open('edges.csv', 'r') as edges_file

这是因为您在一个还不知道文件名的函数中。您想要编写它:当然，with open(edges_file, 'r') as file:，根据需要修改其余的代码.

希望这能有所帮助！祝好运
