Analytics can't generate a model

Hi, after an installation on windows server 2016 of thingworx fondation 8.3.2 and thingworx analytics 8.3 on the same pc, i try to do this guide https://developer.thingworx.com/en/resources/guides/analytics-builder-quickstart/abq-conclusion.

The server apparead connected but when i try to do a model the validation set is nan and i don't see the prediction scroed and the model result.

I don't know well the reason, any suggestions?
