Error in PositionRank: tuple index out of range

[artdream-dubai]

Now there is an error when working with PositionRank, before it was working. I start the example in "Getting started"->Model parameterization and try to check PositionRank. In step-5 : ranking keyphrase candidates there is the error:

IndexError Traceback (most recent call last)
in
3 # 2. graph construction (building a complete-weighted-graph of topics)
4 # 3. rank topics (nodes) using a random walk algorithm
----> 5 extractor.candidate_weighting()

135 if hasattr(graph, "networkx_plugin") and plugins:
136 plugin_name = graph.networkx_plugin

IndexError: tuple index out of range

I kindly ask for your help here,
Thank you for this nice research instrument!
