Python 正在将networkx对象导入到gephi-KeyError:<；类型'；numpy.int64'&燃气轮机；

我不知道是什么破坏了我的代码，但当我试图将我的网络对象导出到一个gephi对象中时，我不断得到密钥错误numpy.int64。我正在遍历comnol列表，并将网络对象放入write_gexf函数中

Combnol = 
[[1992, <networkx.classes.graph.Graph at 0x10dfc5b50>],
 [2000, <networkx.classes.graph.Graph at 0x10dc58650>],

边缘中的值的数据类型是什么？该特定代码正在尝试序列化该值，它会按类型进行序列化。因此，字典中有一个“int”的词条，它基本上调用

str（int）

，但显然没有一个用于numpy int的词条。解决方案：在添加到networkx边缘时转换为“普通”整数，或者将numpy整数的转换添加到networkx源中。已更新以询问您的问题。。。让我试试看，我看不出您在哪里使用numpy.int64类型。但你一定在某个地方。如果要编写graphml，请使用常规Python整数。如何使用常规Python整数？这仅仅意味着写作吗1@user3314418-是的，这不是整数对浮点的事情。你在用numpy吗？如果没有，那么我也不明白为什么会出现这个错误。如果是，那么是的，在添加到图形时只需执行

int（numpy\u int）

。
