Hi @gdragone1, I think the error message says it all.

The last layer of StackNet cannot have a classifier

Could you please tell us what the stack param file looks like ?

Thanks

Param file like this： RandomForestRegression estimators:100 threads:1 rounding:3 cut_off_subsample:0.15 max_depth:7 max_features:0.7 min_leaf:3.0 min_split:5.0 Objective:ENTROPY row_subsample:0.95 seed:1 verbose:false

GradientBoostingForestRegression rounding:3 estimators:1000 shrinkage:0.1 threads:1 offset:0.00001 max_depth:8 max_features:0.4 min_leaf:4.0 min_split:8.0 Objective:RMSE row_subsample:0.7 seed:1 verbose:false

And this param file gives you the error you report ?

That's pretty weird !

Sorry, I remembered it. I fix it already. It's 'RandomForestClassifier' before. Thank you!
