Cannot import sample ML projects from Oracle Analytics Library to OAC

Question

Summary

Content

I've tried to import the three different machine learning sample projects from the Oracle Analytics Library (attrition, numeric, heart disease) but

they fail with the same error:

It looks like we did something wrong. Please try again, but if the problem persists know that we are trying hard to make the product perfect.

Something went wrong and we were unable to import your .dva file. Please check the logs for more details.

Where would these logs exist to determine the problem?

Sometimes a project dashboard is created but the dataset doesn't exist so it only displays an error when the project is opened.

An example would be the Naive Bayes Train-Attrition Analysis.dva project that is part of the Attrition example.

After the installation of DV for Desktop did you install the ML and Python pieces as well? They should be present in your application folder. These two post-installation items are required for any ML or advanced analytics type of project/activity.

This is on OAC, not DV Desktop.  It works fine on DV Desktop.   I believe the ML and Python components are pre-installed in OAC BI Service.
