I am trying to do multi output regression analysis in Catboost. Size of the matrices are:
x_train=(60,20)
y_train=(60,17657)
x_test=(15,20)
y_test=(15,17657)
Relevant code is below:
cat_model=CatBoostRegressor(loss_function="MultiRMSE",n_estimators=5,max_depth=4,
eval_metric="Mult
iRMSE").fit(x_train,y_train,
eval_set=(x_test,y_test)
)
And it returns an error message as "All train targets are equal". Can you help? Thanks.
