  • I was doing a hyper parameter search over GBM (I would expected 108 models to build). 59 of the models build successfully. Sometime building model 60 this failure occurred. It even looks like 6 of 10 of the cross validation models were built. Logs attached. It would be nice to just fix the bug. With that said, it would also be nice to be able to restart a grid search that fails for some reason, but don't repeat building models for parameters that completed successfully (in this case, the system would keep models 1-59 and just add models 60-108 onto the same grid object). Also note that the gbm.grid object is not available in R. Having a handle on the object, even if partially completed, would be good. {noformat} H2O Build git branch master H2O Build git hash 1a955973fbb9beeca0ea08783e79e0584149f68d H2O Build git describe jenkins-master-3300 H2O Build project version 3.7.0.3300 H2O Built by jenkins H2O Built on 2015-12-17 23:32:31 Flow version 0.4.8 {noformat} {noformat} > gbm.hyper.params <- list(ntrees=c(100,300,1000), learn_rate=c(0.1,0.03,0.01), col_sample_rate_per_tree=c(1,0.7), max_depth=c(2,5,10), sample_rate=c(1,0.7) ) > gbm.grid <- h2o.grid(algorithm = "gbm", grid="gbm.grid", x=x.columns, y=y.column.h2o, training_frame=h2o.train, nfolds=10, distribution="multinomial", hyper_params = gbm.hyper.params) |=============================================================================================== | 56% Got exception 'class java.lang.AssertionError', with msg 'null' java.lang.AssertionError at hex.tree.DTree$UndecidedNode.scoreCols(DTree.java:301) at hex.tree.DTree$UndecidedNode.<init>(DTree.java:274) at hex.tree.DTree$DecidedNode.makeUndecidedNode(DTree.java:422) at hex.tree.DTree$DecidedNode.<init>(DTree.java:493) at hex.tree.SharedTree.makeDecided(SharedTree.java:491) at hex.tree.SharedTree$ScoreBuildOneTree.onCompletion(SharedTree.java:438) at jsr166y.CountedCompleter.__tryComplete(CountedCompleter.java:425) at jsr166y.CountedCompleter.tryComplete(CountedCompleter.java:383) at water.MRTask.compute2(MRTask.java:689) at water.H2O$H2OCountedCompleter.compute1(H2O.java:1060) at hex.tree.ScoreBuildHistogram$Icer.compute1(ScoreBuildHistogram$Icer.java) at water.H2O$H2OCountedCompleter.compute(H2O.java:1056) at jsr166y.CountedCompleter.exec(CountedCompleter.java:468) at jsr166y.ForkJoinTask.doExec(ForkJoinTask.java:263) at jsr166y.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:974) at jsr166y.ForkJoinPool.runWorker(ForkJoinPool.java:1477) at jsr166y.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:104) Error: 'null' > gbm.grid Error: object 'gbm.grid' not found {noformat} This appears at the tail of the log {noformat} 12-21 02:08:47.594 127.0.0.1:54321 90094 FJ-1-9 INFO: 96. tree was built in 00:00:00.149 (Wall: 21-Dec 02:08:47.594) 12-21 02:08:47.750 127.0.0.1:54321 90094 FJ-1-9 INFO: 97. tree was built in 00:00:00.156 (Wall: 21-Dec 02:08:47.750) 12-21 02:08:47.894 127.0.0.1:54321 90094 FJ-3-13 ERRR: Error: Missing chunk 6 for $04ffb4000000ffffffff14b16c1fc73c32bab142df427378eb$P 12-21 02:08:47.896 127.0.0.1:54321 90094 FJ-3-15 ERRR: Error: Missing chunk 0 for $04ff85000000ffffffff14b16c1fc73c32bab142df427378eb$P {noformat}

  • I was doing a hyper parameter search over GBM (I would expected 108 models to build). 59 of the models build successfully. Sometime building model 60 this failure occurred. It even looks like 6 of 10 of the cross validation models were built. Logs attached. It would be nice to just fix the bug. With that said, it would also be nice to be able to restart a grid search that fails for some reason, but don't repeat building models for parameters that completed successfully (in this case, the system would keep models 1-59 and just add models 60-108 onto the same grid object). Also note that the gbm.grid object is not available in R. Having a handle on the object, even if partially completed, would be good. {noformat} H2O Build git branch master H2O Build git hash 1a955973fbb9beeca0ea08783e79e0584149f68d H2O Build git describe jenkins-master-3300 H2O Build project version 3.7.0.3300 H2O Built by jenkins H2O Built on 2015-12-17 23:32:31 Flow version 0.4.8 {noformat} {noformat} > gbm.hyper.params <- list(ntrees=c(100,300,1000), learn_rate=c(0.1,0.03,0.01), col_sample_rate_per_tree=c(1,0.7), max_depth=c(2,5,10), sample_rate=c(1,0.7) ) > gbm.grid <- h2o.grid(algorithm = "gbm", grid="gbm.grid", x=x.columns, y=y.column.h2o, training_frame=h2o.train, nfolds=10, distribution="multinomial", hyper_params = gbm.hyper.params) |=============================================================================================== | 56% Got exception 'class java.lang.AssertionError', with msg 'null' java.lang.AssertionError at hex.tree.DTree$UndecidedNode.scoreCols(DTree.java:301) at hex.tree.DTree$UndecidedNode.<init>(DTree.java:274) at hex.tree.DTree$DecidedNode.makeUndecidedNode(DTree.java:422) at hex.tree.DTree$DecidedNode.<init>(DTree.java:493) at hex.tree.SharedTree.makeDecided(SharedTree.java:491) at hex.tree.SharedTree$ScoreBuildOneTree.onCompletion(SharedTree.java:438) at jsr166y.CountedCompleter.__tryComplete(CountedCompleter.java:425) at jsr166y.CountedCompleter.tryComplete(CountedCompleter.java:383) at water.MRTask.compute2(MRTask.java:689) at water.H2O$H2OCountedCompleter.compute1(H2O.java:1060) at hex.tree.ScoreBuildHistogram$Icer.compute1(ScoreBuildHistogram$Icer.java) at water.H2O$H2OCountedCompleter.compute(H2O.java:1056) at jsr166y.CountedCompleter.exec(CountedCompleter.java:468) at jsr166y.ForkJoinTask.doExec(ForkJoinTask.java:263) at jsr166y.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:974) at jsr166y.ForkJoinPool.runWorker(ForkJoinPool.java:1477) at jsr166y.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:104) Error: 'null' > gbm.grid Error: object 'gbm.grid' not found {noformat} This appears at the tail of the log {noformat} 12-21 02:08:47.594 127.0.0.1:54321 90094 FJ-1-9 INFO: 96. tree was built in 00:00:00.149 (Wall: 21-Dec 02:08:47.594) 12-21 02:08:47.750 127.0.0.1:54321 90094 FJ-1-9 INFO: 97. tree was built in 00:00:00.156 (Wall: 21-Dec 02:08:47.750) 12-21 02:08:47.894 127.0.0.1:54321 90094 FJ-3-13 ERRR: Error: Missing chunk 6 for $04ffb4000000ffffffff14b16c1fc73c32bab142df427378eb$P 12-21 02:08:47.896 127.0.0.1:54321 90094 FJ-3-15 ERRR: Error: Missing chunk 0 for $04ff85000000ffffffff14b16c1fc73c32bab142df427378eb$P {noformat}

  • Error in running h2o.ensemble
    via Stack Overflow by saurabh agarwal
    ,
  • When running a default random forest with about 800,000 predictions against a target with a wide range, it stops running almost immediately with the error shown below. I was able to work around the issue by turning off assertions in h2o.init(). I used the same code I have used in the past. Whatever assertion is causing the problem needs to be removed. Typical use should not require any non-default options to run a fairly straightforward model. I will try to post the data set to a server for reproduction, but I believe the assertion decision can likely be conducted without the need for reproduction (it should be OK and even encouraged to have pure splits created while fitting a RF model). > rf<-h2o.randomForest(x = c("Sales",modelingColumns),y="Sales",training_frame = trainHex,validation_frame = validHex,model_id = "rf1") | | 0% Got exception 'class java.lang.AssertionError', with msg 'null' java.lang.AssertionError at hex.tree.DHistogram.scoreMSE(DHistogram.java:323) at hex.tree.DTree$DecidedNode$FindSplits.compute2(DTree.java:441) at hex.tree.DTree$DecidedNode.bestCol(DTree.java:421) at hex.tree.DTree$DecidedNode.<init>(DTree.java:449) at hex.tree.SharedTree.makeDecided(SharedTree.java:481) at hex.tree.SharedTree$ScoreBuildOneTree.onCompletion(SharedTree.java:428) at jsr166y.CountedCompleter.__tryComplete(CountedCompleter.java:425) at jsr166y.CountedCompleter.tryComplete(CountedCompleter.java:383) at water.MRTask.compute2(MRTask.java:682) at water.H2O$H2OCountedCompleter.compute(H2O.java:1061) at jsr166y.CountedCompleter.exec(CountedCompleter.java:468) at jsr166y.ForkJoinTask.doExec(ForkJoinTask.java:263) at jsr166y.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:974) at jsr166y.ForkJoinPool.runWorker(ForkJoinPool.java:1477) at jsr166y.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:104) Error: 'null' In addition: Warning messages: 1: In .verify_dataxy(training_frame, x, y) : removing response variable from the explanatory variables 2: In .h2o.validateModelParameters(algo, param_values, h2oRestApiVersion) : Dropping constant columns: Open, StateHoliday.
