> Key: IGNITE-12658
> URL: https://issues.apache.org/jira/browse/IGNITE-12658
> Project: Ignite
> Issue Type: Bug
> Components: examples, ml
> Affects Versions: 2.8
> Environment: Ubuntu/Win
> Java 8
> Reporter: Stepan Pilschikov
> Assignee: Alexey Zinoviev
> Priority: Critical
> Fix For: 2.8
>
>
> Steps to reproduce:
> 1. Run Ignite node with org.apache.ignite.examples.ExampleNodeStartup (1 node will be enough)
> 2. Run org.apache.ignite.examples.ml.tutorial.TutorialStepByStepExample
> Actual:
> On Step_8_CV_with_Param_Grid_and_metrics starting to throw a lot of exceptions
> {code:java}
> Train with p: 2 and maxDeep: 1
> >>> Trained model: if (x1 > 0.4368) then return 1.0000 else return 0.0000
> >>> Accuracy 0.7679083094555874
> >>> Test Error 0.2320916905444126
> >>> Tutorial step 8 (cross-validation) example completed.
> [13:25:40] Ignite node stopped OK [uptime=00:00:17.453]
> >>> Tutorial step 8 (cross-validation with param grid) example started.
