为什么我的 "networkx" 图不准确并且没有可视化我的输入数据？
Why my "networkx" plot is inaccurate and does not visualize my input data?
我正在尝试使用 Python 的“networkx”库可视化网络拓扑。但输出不准确，与预期不同。尤其是边缘没有显示，输出图没有组织，乱七八糟，不准确。
我的代码：
import networkx as nx
import matplotlib.pyplot as plt
import re
f = open("topology.conf", "r")
G = nx.Graph()
flag = 111
root = ''
for line in f:
for word in re.split(',|=| ', line):
if flag == 0:
root = word
flag = 111
if flag == 1:
G.add_edge(root, word)
flag = 111
if word == 'SwitchName':
flag = 0
continue
if word == 'Switches' or word == 'Nodes':
flag = 1
continue
nx.draw(G, with_labels=False)
plt.show()
f.close()
在与网络拓扑相关的输入数据中，“SwitchName”与“Switches”或“Nodes”中的每一项之间存在连接。
要可视化的输入数据：

最后，输出文件应该是这样的（不完全一样，但格式类似）
预期输出
我认为问题出在您的解析中。您可以通过在代码中打印所有边缘（通过添加行 [e for e in G.edges]）来检查它。这是解决问题的示例：
import networkx as nx
import matplotlib.pyplot as plt
import re
f = open("topology.conf", "r")
G = nx.Graph()
for line in f:
seg = re.split(' ', line)
sources = re.split('=', seg[0])
source = sources[1]
for word in re.split(',|=| ', seg[1]):
if word == 'Switches' or word == 'Nodes':
continue
G.add_edge(source, word.strip())
nx.draw(G, with_labels=False)
plt.show()
f.close()
# [e for e in G.edges]
这是示例输出：
我正在尝试使用 Python 的“networkx”库可视化网络拓扑。但输出不准确，与预期不同。尤其是边缘没有显示，输出图没有组织，乱七八糟，不准确。
我的代码：
import networkx as nx
import matplotlib.pyplot as plt
import re
f = open("topology.conf", "r")
G = nx.Graph()
flag = 111
root = ''
for line in f:
for word in re.split(',|=| ', line):
if flag == 0:
root = word
flag = 111
if flag == 1:
G.add_edge(root, word)
flag = 111
if word == 'SwitchName':
flag = 0
continue
if word == 'Switches' or word == 'Nodes':
flag = 1
continue
nx.draw(G, with_labels=False)
plt.show()
f.close()
在与网络拓扑相关的输入数据中，“SwitchName”与“Switches”或“Nodes”中的每一项之间存在连接。

最后，输出文件应该是这样的（不完全一样，但格式类似）
预期输出
我认为问题出在您的解析中。您可以通过在代码中打印所有边缘（通过添加行 [e for e in G.edges]）来检查它。这是解决问题的示例：
import networkx as nx
import matplotlib.pyplot as plt
import re
f = open("topology.conf", "r")
G = nx.Graph()
for line in f:
seg = re.split(' ', line)
sources = re.split('=', seg[0])
source = sources[1]
for word in re.split(',|=| ', seg[1]):
if word == 'Switches' or word == 'Nodes':
continue
G.add_edge(source, word.strip())
nx.draw(G, with_labels=False)
plt.show()
f.close()
# [e for e in G.edges]
这是示例输出：
