Parameter Optimization - Process Failed

Good day,


I tried to optimize parameters (learning rate, momentum via X-VAL / NN) by either using Optimize Parameters Grid or Evolutionary but received an error message as "process failed." You can see from attached screenshot.

What can be the problem and how can I fix it?


Thank you.


Have a nice day.

    Try adjusting the range of LR and Mom parameters. I've noticed that sometimes when I put the lower range of LR and Mom on a Neural Net to 0.1 in Optimize Parameters, it gives me trouble.
