In (cell 32](https://github.com/neo4j-graph-analytics/ml-link-prediction-notebooks/blob/main/04_Predictions.ipynb), I get an IndexError:

Sorry for leaving this out. I've edited the original post too.	Component	Version
Neo4j	4.3.1
GDS	1.6.1

[tomasonjo]

I have tested it and it works on my end with the latest GDS 1.6.4. Have you executed all the previous cells? Try to update your GDS/py2neo version if it doesn't work.
