Question

当我写入pajek文件然后使用Networkx库python读回同一文件时，我收到错误

   >>> G=nx.read_pajek("eatRS.net")

   >>> nx.write_pajek(G,"temp.net")

   >>> G1=nx.read_pajek("temp.net")

Traceback (most recent call last):

 ValueError: No closing quotation

在networkx中创建图形，以pajek格式写入然后再返回可以正常工作。例如。与gnm_random_graph：

import matplotlib.pyplot as np
n = 10
m = 20

G = nx.gnm_random_graph(n,m)
nx.write_pajek(G, "temp.net")
G1 = nx.read_pajek("temp.net")

仅当我编辑中间图时才有，例如</ p>

"vertex one 0.3456 0.1234 box ic White fos 20

我遇到ValueError: No closing quotation错误吗？节点标签可以是数字或字符串，但如果它们包含空格，则必须引用该名称。从Pajek manual：

标签 - 如果标签以字符A..Z或0..9开头，则第一个空白确定标签的结尾（例如：vertex1），由更多单词组成的标签必须包含在特殊对中字符（例如：“vertex 1”）

因此，我建议您检查输入文件“eatRS.net”。也许字符编码，引号不匹配（例如用"打开，用'结束）或节点标签中的换行符有问题？

在Networkx中读取和写入错误pajek文件
