StackNet: Can't run lightgbm with config file

Hello, Thank you for providing an example with the zillow competition. I tried running the example but came with exactly the same problem as here: https://github.com/kaz-Anova/StackNet/issues/16

I can’t run lgbm and I have exactly the same output error:

Starting cross validation Fitting model : 0 Exception in thread “Thread-1” java.lang.IllegalStateException: failed to create LIGHTgbm subprocess with config name /Users/hadoop/StackNet/models/ucsbmggugdanr6qc19a64a7sv10.conf at ml.lightgbm.LightgbmRegressor.create_light_suprocess(LightgbmRegressor.java:426) at ml.lightgbm.LightgbmRegressor.fit(LightgbmRegressor.java:1885) at ml.lightgbm.LightgbmRegressor.run(LightgbmRegressor.java:516) at java.lang.Thread.run(Thread.java:748) Exception in thread “main” java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:58) Caused by: java.lang.IllegalStateException: Tree is not fitted at ml.Bagging.scoringhelperbagv2.<init>(scoringhelperbagv2.java:109) at ml.Bagging.BaggingRegressor.predict2d(BaggingRegressor.java:669) at ml.Bagging.BaggingRegressor.predict_proba(BaggingRegressor.java:1875) at ml.stacknet.StackNetRegressor.fit(StackNetRegressor.java:3065) at stacknetrun.runstacknet.main(runstacknet.java:522) … 5 more

I tried to run lightgbm by itself by running it with the config file:

./lightgbm config=~ ./models/ucsbmggugdanr6qc19a64a7sv10.conf task=train

But I receive a ‘Permission denied’ error. I tried running the same command with sudo but I get

sudo: ./lightgbm: command not found

I checked and the jar file is in the same folder as the lib folder. Here is a screenshot of how my Stacknet folder is organized:

Thank you for your help.
