[英]Reading a Multigraph in NetworkX from gml file
I am attempting to read a gml file into a multigraph object; 我正在尝试将gml文件读入多图对象; however, I am receiving the following error:
但是,我收到以下错误:
NetworkXError: edge #1 (0--3) is duplicated
In the gml file the the edge is duplicated: 在gml文件中,边缘是重复的:
edge [
source 0
target 3
LinkLabel "Green"
]
edge [
source 0
target 3
LinkLabel "Brown"
]
As I understand it, the read_gml function should return a multigraph when the input is a multigraph. 据我了解,当输入为多图时,read_gml函数应返回多图。 What am I missing?
我想念什么?
Your gml file probably lacks of multigraph 1
below graph [
. 您的gml文件可能缺少
graph [
之下的multigraph 1
。 Here is a MWE. 这是MWE。
import networkx as nx
G = nx.read_gml('test.gml')
print(type(G)) # <class 'networkx.classes.multigraph.MultiGraph'>
print(G.edges(data=True)) # [(0, 3, {u'LinkLabel': u'Green'}), (0, 3, {u'LinkLabel': u'Brown'})]
The content of test.gml
, test.gml
的内容,
graph [
multigraph 1
node [
id 0
label 0
]
node [
id 3
label 3
]
edge [
source 0
target 3
LinkLabel "Green"
]
edge [
source 0
target 3
LinkLabel "Brown"
]
