## Créer un environnement virtuel { #create-a-virtual-environment }

Lorsque vous commencez à travailler sur un projet Python pour la première fois, créez un environnement virtuel <strong><dfn title="il existe d'autres options, il s'agit d'une simple recommandation">dans votre projet</dfn></strong>.

Vous n’avez besoin de faire cela qu’une seule fois par projet, pas à chaque fois que vous travaillez.

Exemplos comuns de operações limitadas por CPU são coisas que exigem processamento matemático complexo.

Por exemplo:

* **Processamento de áudio** ou **imagem**
* **Visão Computacional**: uma imagem é composta por milhões de pixels, cada pixel tem 3 valores / cores, processar isso normalmente exige alguma computação em todos esses pixels ao mesmo tempo

OkHttp 4.0, we kept our Java-first APIs. With 5.0 we're continuing to support Java and adding
additional improvements for Kotlin users. In this alpha we're excited to skip-the-builder for
requests and remove a common source of non-null assertions (`!!`) on the response body.

The alpha releases in the 5.0.0 series have production-quality code and an unstable API. We expect
