Advanced analytics toolbox extension in qlik loads idefinitely

[Filaz]

Hello,

I have been trying to use this Advanced Analytics toolbox, but I am not being too successful and I don't really know why. I have been trying to do the examples for the decision tree from over here:
https://github.com/mhamano/advanced-analytics-toolbox/blob/master/docs/analysis/decision_tree.md
Despite my attempts, what happens is that the extension stays in a calculating state indefinitely. I am using Qliksense Novmeber 2018 Patch 1 (12.44.2).

Any reason for this happening, that you could help me identify?

Thank you,
André Braga

This is what both Rserve and SSEtoRserve look like at the time:
