Django application deployment with ASGI server

I am trying to deploy Django application with ASGI server, I am following this tutorial(https://www.digitalocean.com/community/tutorials/how-to-set-up-an-asgi-django-app-with-postgres-nginx-and-uvicorn-on-ubuntu-20-04). When I run this command (gunicorn --bind 0.0.0.0:8000 myproject.asgi -w 4 -k uvicorn.workers.UvicornWorker). This is the error

Error: class uri ‘uvicorn.workers.UvicornWorker’ invalid or not found:
