ThingWorx-Analytics: Creation of predictive model failed

Hello all,

 

I want to create a predictive model with an ordinal goal variable based on a time series dataset of around one million entries. Unfortunatly the creation always failed with the error you can find in the attachment. Does anybody know how I can fix this problem?

 

Here are some more information:

- ThingWOrx Version: ThingWorx 9.0.2

- Used learners in the model: Neural_Net, Decision_Tree and Gradient_Boost

- Used Ensambler: Average

- LookbackSize: 4

- No use of goal history

 

Thank you already in adcance.

 

Kind regards 

David

Hi David

 

 

From the screenshot you posted, the issue is due to an OutOfMemory error. This happens when working on large dataset.

Try the steps from https://www.ptc.com/en/support/article/CS294545 to increase the memory allocated to the workers

 

Thanks

Christophe

Hi @DF_10027356 

 

Could you then download the TWALogCollector , execute it on the ThingWorx Analytics machine and post the resulting zip or gz file here ?

 

Thank you

Christophe
