How to check Rasa is use GPU

Hello. I’m new in Rassa. My os Ubuntu 18.04. I installed Rasa x full from belowing link with docker compose.

When i train my model on rasa-x i takes 5-6 minutes. There is approximately 50-60 nlu data, 20 response and 20 stories.

It takes so longer. My host has GPU. I dont change anything in docker-compose,install.sh files. How to check rasa is use my GPU or how to activate it?
