Importance Weights Troubleshooting

Question

Dear all,

I am trying to take my first steps towards using importance weights for a problem.

I receive an error that the R.exe indicated an error but no more details. How can I understand what is problematic?

My Alteryx viersion: 2019.2.7

R installation for Alteryx is in ..\C:\Program Files\Alteryx and its R version is 3.5.3.

Best,

Atamert

Hi @atamertarslan,

can you please check the option "Show All Macro Messages" from the Runtime tab in your workflow configuration?

If you re-run the workflow then, you'll probably get more messages to help you troubleshoot what the problem is. In general, R errors from Predictive Tools are very likely due to value distributions in your fields (you might have a field with 1 unique value, or fields with Nulls, ...).

See here: https://community.alteryx.com/t5/Data-Science-Blog/Troubleshooting-the-Predictive-Tools/ba-p/8593

Hope this helps,

Giuseppe
