networkx keyerror due to "long" format

I am getting an error:

KeyError: 'long'

when I run this code:

import networkx as nx
graph_input = open("final_graphml_train/myhead.txt", mode='rb')
graph = nx.read_graphml(graph_input)

The file looks like this:

<?xml version='1.0' encoding='utf-8'?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd">
  <key id="d20" for="edge" attr.name="key" attr.type="long" />
</graphml>

I have checked the documentation that allows the "long" format.

http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd

key.type.type is a restriction of xs:NMTOKEN Allowed values: boolean, int, long, float, double, string.

How do I avoid the keyerror in networkx?

Solution

  • Upgrade to the newest version of networkx, it is working as of networkx version 2.6.2.

    pip install networkx --upgrade
