    RESULT: A message "Model activation failed".

Cause

This message can be triggered for different reasons. Two options are:

  1. Only one model can be active at any time. If you already have another model active, is needed to deactivate one to activate the other.

Resolution

The most probable cause for the Predictive Power being lower than 50% is the data quality. Get an idea about the data quality while training the model. Also get a glimpse of the data quality by looking at the Readiness Report.
