E você normalmente instalaria essas dependências de pacote com `pip`, por exemplo:

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic uvicorn

Если ранее вы использовали другой асинхронный фреймворк, который работает иначе,
и привыкли объявлять простые вычислительные *функции* через `def` ради
незначительного прироста скорости (порядка 100 наносекунд), обратите внимание,
что с **FastAPI** вы получите противоположный эффект. В таком случае больше подходит
`async def`, если только *функция обработки пути* не использует код, приводящий

    protected List<String> deleteUrlList = new ArrayList<>(100);

    /** Maximum size of the delete URL cache before batch deletion is triggered. */
    protected int maxDeleteDocumentCacheSize;

    /** Maximum number of redirects to follow when processing URLs. */

 * NullPointerTester}, the caller can provide a custom non-null default value for the parameter type

Yukarıda açıklanan şekilde çalışmayan başka bir asenkron framework'den geliyorsanız ve küçük bir performans kazancı (yaklaşık 100 nanosaniye) için  "def" ile *path fonksiyonu* tanımlamaya alışkınsanız, **FastAPI**'de tam tersi olacağını unutmayın. Bu durumlarda, *path fonksiyonu* <abbr title="Input/Output: disk okuma veya yazma, ağ iletişimleri.">G/Ç</abbr> engelleyen durum oluşturmadıkça...
