NPE with weighted sum #49

Closed potz378 closed 4 years ago

potz378 commented 4 years ago

Hello i got a problem in trying to convert a model into a pmml file here is the code:

best_param['n_estimators'] = best4.best_ntree_limit xgb_pipeline = PMMLPipeline([("mapper", DataFrameMapper( [(i, None) for i in best4.feature_names])), ("classifier", XGBClassifier(**best_param))])

xgb_pipeline.fit(X_train, y_train)

sklearn2pmml(xgb_pipeline,path + '/test.pmml', with_repr=True, debug=True)

And i got the error SEVERE: Failed to convert java.lang.NullPointerException
