Pour voir un exemple, allez voir les [Générateurs de projets](../project-generation.md){.internal-link target=_blank}, ils incluent tous Celery déjà configuré.

Mais si vous avez besoin d'accéder aux variables et objets de la même application **FastAPI**, ou si vous avez besoin d'effectuer de petites tâches d'arrière-plan (comme envoyer des notifications par email), vous pouvez simplement vous contenter d'utiliser `BackgroundTasks`.

## Recap

## Global Dependencies

many machines in a cluster, and within a machine across multiple computational devices, including multicore CPUs, general purpose GPUs, and custom-designed ASICs known as Tensor Processing Units (TPUs). This architecture gives flexibility to the application developer, whereas in previous “parameter server” designs the management of shared state is built into the system, TensorFlow enables developers to experiment with novel optimizations and training algorithms. TensorFlow supports a variety of applications,...
