title: Import multigraph into Gephi from GML format
body: <p>I use NetworkX to create a set of nodes and edges and export them into GML format so that I can view them on Gephi 0.9.1 version. When I import the following GML:</p>
  
  <pre><code>graph [
    multigraph 1
    directed 0
    node [
      id 0
      label 1
    ]
    node [
      id 1
      label 2
    ]
    edge [
      source 0
      target 1
      key "rel2"
    ]
    edge [
      source 0
      target 1
      key "rel1"
    ]
  ]
  </code></pre>
  
  <p>Gephi shows the following popup:
  <a href="https://i.stack.imgur.com/Gac1s.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Gac1s.png" alt="Import multigraph into gephi"></a></p>
  
  <p>It said <code>Multi Graph: no</code> while in the GML it is stated <code>multigraph 1</code>.
  Gephi automatically merges the edges, and sets the weight to <code>2</code>, as below:</p>
  
  <p><a href="https://i.stack.imgur.com/l5tGG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/l5tGG.png" alt="Weight = 2"></a></p>
  
  <p>How can I configure Gephi to read a multigraph? Should I change my GML or any settings in Gephi? Or it is a bug?</p>
