<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Примечание**: Обязательно заключите `"fastapi[standard]"` в кавычки, чтобы это работало во всех терминалах.

## Пример { #example }

### Создание { #create-it }

diesem Fall könnte es besser sein, nur zwei Server zu haben und einen höheren Prozentsatz von deren Ressourcen zu nutzen (CPU, Arbeitsspeicher, Festplatte, Netzwerkbandbreite, usw.).

Wenn Sie andererseits über zwei Server verfügen und **100 % ihrer CPU und ihres RAM** nutzen, wird irgendwann ein Prozess nach mehr Speicher fragen und der Server muss die Festplatte als „Speicher“ verwenden (was tausendmal langsamer sein kann) oder er könnte sogar **abstürzen**. Oder ein Prozess muss möglicherweise...

In that case, it could be better to have only 2 servers and use a higher percentage of their resources (CPU, memory, disk, network bandwidth, etc).

```
fastapi>=0.68.0,<0.69.0
pydantic>=1.8.0,<2.0.0
uvicorn>=0.15.0,<0.16.0
```

你通常会使用`pip`安装这些依赖项：

<div class="termy">

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

</div>

还有其他文件格式和工具来定义和安装依赖项。

 我将在下面的部分中向你展示一个使用 Poetry 的示例。 👇

### 创建 **FastAPI** 代码

* There should be tests testing the source example.
* Before the PR is applied, the new tests should fail.
* After applying the PR, the new tests should pass.
* Coverage should stay at 100%.
* If you see the PR makes sense, or we discussed it and considered it should be accepted, you can add commits on top of the PR to tweak it, to add docs, tests, format, refactor, remove extra files, etc.

Primeiro, certifique-se de criar seu [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e, em seguida, instalar o `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## Criar o App com um Único Modelo { #create-the-app-with-a-single-model }

Vamos criar a primeira versão mais simples do app com um único modelo **SQLModel**.

	for index := range buckets {
		g.Go(func() error {
			// Sleep and stagger to avoid blocked CPU and thundering
			// herd upon start up sequence.
			time.Sleep(25*time.Millisecond + time.Duration(rand.Int63n(int64(100*time.Millisecond))))

			_, _ = sys.objAPI.HealBucket(ctx, buckets[index], madmin.HealOpts{Recreate: true})
			meta, err := loadBucketMetadata(ctx, sys.objAPI, buckets[index])
			if err != nil {
				return err
			}

<div class="termy">

```console
$ pip install "fastapi[standard]"

```

</div>

**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals.

## Example

### Create it

Create a file `main.py` with:

```Python

fastapi>=0.68.0,<0.69.0
pydantic>=1.8.0,<2.0.0
uvicorn>=0.15.0,<0.16.0
```

그리고 일반적으로 패키지 종속성은 `pip`로 설치합니다. 예를 들어:

<div class="termy">

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

</div>

/// info | 정보

패키지 종속성을 정의하고 설치하기 위한 방법과 도구는 다양합니다.

나중에 아래 세션에서 Poetry를 사용한 예시를 보이겠습니다. 👇
