You can, but Celery has pretty tight integration with Django so it's easy to write a Django app that includes a bunch of Celery tasks if you're going that route. Also, it's not entirely straightforward to run a web app written in another language which runs some of its async tasks via Celery. If you know you want access to the data science ecosystem of libraries Django is a solid choice.
