How to make LightGBM to suppress output? I'm trying for a while to figure out how to "shut up" LightGBM. Especially, I want to suppress the output of LightGBM during training (the feedback on the boosting steps).

My model:

params = {
            'objective': 'regression',
            'learning_rate' :0.9,
            'max_depth' : 1,
            'metric': 'mean_squared_error',
            'seed': 7,
            'boosting_type' : 'gbdt'
        }

gbm = lgb.train(params,
                lgb_train,
                num_boost_round=100000,
                valid_sets=lgb_eval,
                early_stopping_rounds=100)


I tried to add verbose=0 as suggested in the docs. But this does not work.

Does anyone know how to suppress LightGBM output during training?
As @Peter has suggested, setting verbose_eval = -1 suppresses most of LightGBM output (link: here).

However, LightGBM may still return other warnings - e.g. No further splits with positive gain. This can be suppressed as follows (source: here ):

lgb_train = lgb.Dataset(X_train, y_train, params={'verbose': -1}, free_raw_data=False)
lgb_eval = lgb.Dataset(X_test, y_test, params={'verbose': -1},free_raw_data=False)
gbm = lgb.train({'verbose': -1}, lgb_train, valid_sets=lgb_eval, verbose_eval=False)
