Hello! I am trying to run the example in: https://tbgraph.wordpress.com/2018/10/17/feature-extraction-on-a-peer-to-peer-network-with-deepgl-embedding-and-neo4j/ This example uses the Gnutella [dataset](http://snap.stanford.edu/data/p2p-Gnutella09.html). At some point, the DeepGL algorithm is called: > CALL embedding.deepgl("Host","CONNECTION", { nodeFeatures: ['pagerank'],...

Hi, I try to figure out how to properly set the number of desired features with embedding.deepgl algorithms. Currently, my setup goes as follows: ``` CALL embedding.deepgl( null, null, {...
