ShaggyHare67 notice that the services queue is designed to run CPU based tasks like monitoring etc.
For the actual training you need to run your trains-agent on a GPU machine.
Did you run the trains-agent init ? it will walk you through the configuration (git user/pass) included.
If you want to manually add them, you can see an example of the configuration file in the link below.
You can find it on ~\trains.conf
