3 years ago LGBMRegressor does indeed have a get_params and the resulting json-ld looks then like this:

}On the other hand when I follow https://github.com/microsoft/LightGBM/blob/master/examples/python-guide/simple_example.py I get a Booster object which has no get_params. But it has a params attribute that returns
{'boosting_type': 'gbdt', 'objective': 'regression', 'metric': {'l2', 'l1'}, 'num_leaves': 31, 'learning_rate': 0.05, 'feature_fraction': 0.9, 'bagging_fraction': 0.8, 'bagging_freq': 5, 'verbose': 0, 'num_iterations': 20, 'early_stopping_round': 5}Maybe it is good enough to just support these two apis; I'm not sure. Looking through the other examples so far all I see are instances of lgb.train which should return the Booster object, or LGBMRegressor.
