Vizio Template Help

Configuration
1

Cant seem to get templating to work with my home assistant. The below config gives me this error Platform error media_player.template - No module named ‘homeassistant.components.template.media_player’ I then followed the directions here https://github.com/Sennevds/media_player.template/issues/2 to add all the custom components listed in. Does anyone have a vizio template they can share? Trying to setup a custom lovelace remote for my vizio tv and cant seem to get anywhere with the template.
