Hi,
I tried testing interaction constraint feature from command line arguments.
added below args to the basic args -
split_evaluator=“interaction”
interaction_constraints= ‘[[2,3,4],[6,7,8]]’
But got runtime error “InteractionConstraint must be given an inner evaluator”
Please guide me, what is inner evaluator I should provide for executing interaction constraint feature.
I have used basic args as following:
$XGBOOSTCODE/xgboost
$XGBOOSTCODE/xgb.conf
booster=gbtree task=train
train_path=input.libsvm
fmap=attr.fmap
nthread=50 num_round=5 max_depth=3 learning_rate=0.1 min_child_weight=20
reg_lambda=0 min_split_loss=0 objective=binary:logistic
model_out=intercation.model
tree_method=exact
save_period=0
predictor=cpu_predictor
