Getting an error while downloading the Training model, and I am unable to install the application.
Would it be related to page builder role setup ?
It may be related to your user role, but there could be other factors as well. The Anaplan Customer Care (Support) team can help you sort that out, so reach out to them. You can also search your workspace for the model to see if someone else has already downloaded it. If so, you can use Manage Models to make your own copy to practice with.
