Tojo James Posted June 10, 2020 Share Posted June 10, 2020 I have been trying to use the decision tree (MADlib) operator in Team Studio but the following error shows up. "Execution of 'Decision Tree Classification (CART)' failed. Error details: MADlib version 1.7 or higher must be installed on target database". The same error shows up when I am using any operator associated with MADlib. Is there a way to solve this issue Can I upgrade MADlib version on my system Link to comment Share on other sites More sharing options...
Noora Husseini Posted June 10, 2020 Share Posted June 10, 2020 Hi Tojo, That particular version of Decision Tree operator "Decision Tree Classification (CART)" runs on a PostgreSQL database and requires some special functions to be installed in the database. If you can only access the data through PostgreSQL then you will need to install them. If the data location is flexible, you can use a Hadoop data source instead. You should then be able to use the Decision Tree operator with no error. Thanks, Noora Link to comment Share on other sites More sharing options...
