  from gremlin_python.structure.graph import Graph
  from gremlin_python import statics
  from gremlin_python.process.graph_traversal import __
  from gremlin_python.process.strategies import *
  from gremlin_python.process.traversal import *
  import asyncio
  statics.load_statics(globals()) 
  </code></pre>
  
  <p>When i run this: </p>
  
  <pre><code>graph = TinkerGraph.open() 
  graph.io(graphml()).readGraph('air-routes.graphml') 
  </code></pre>
  
  <p>i get the following error:</p>
