Tree is not fitted when using KerasnnRegressor #31

Open SheliaXin opened 7 years ago

SheliaXin commented 7 years ago

When I use KerasnnRegressor on Mac , it gives me the error:

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:497) at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:58) Caused by: java.lang.IllegalStateException: Tree is not fitted at ml.Bagging.scoringhelperbagv2.(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

Can you help me with that? Thanks!

I used:

KerasnnRegressor loss:mean_absolute_error standardize:true use_log1p:true shuffle:true batch_normalization:true weight_init:lecun_uniform momentum:0.9 optimizer:adam use_dense:true l2:0.000001,0.000001 hidden:50,50 activation:relu,relu droupouts:0.1,0.1 epochs:20 lr:0.01 batch_size:8 stopping_rounds:10 validation_split:0.2 seed:1 verbose:false

Can you rerun and put verbose:true and print what it says?
