/// tip | Подсказка

Иногда при попытке обновить pip вы можете получить ошибку **`No module named pip`**.

Если это произошло, установите и обновите pip с помощью команды ниже:

<div class="termy">

```console
$ python -m ensurepip --upgrade

---> 100%
```

</div>

         * So this is probably just the "Windows Java 8" case. In that case, if we wanted *another*
         * layer of fallback before consulting the system property, we could try
         * com.sun.security.auth.module.NTSystem.
         *
         * But for now, we use the value from the system property as our best guess.

Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.

In einer echten Anwendung würden Sie Ihre Tests wahrscheinlich in einer anderen Datei haben.

Und Ihre **FastAPI**-Anwendung könnte auch aus mehreren Dateien/Modulen, usw. bestehen.

### **FastAPI** Anwendungsdatei { #fastapi-app-file }

Nehmen wir an, Sie haben eine Dateistruktur wie in [Größere Anwendungen](bigger-applications.md){.internal-link target=_blank} beschrieben:

```

	logger.LogIf(ctx, "tier", err, errKind...)
}

func kmsLogIf(ctx context.Context, err error, errKind ...any) {
	logger.LogIf(ctx, "kms", err, errKind...)
}

// KMSLogger permits access to kms module specific logging
type KMSLogger struct{}

// LogOnceIf is the implementation of LogOnceIf, accessible using the Logger interface
func (l KMSLogger) LogOnceIf(ctx context.Context, err error, id string, errKind ...any) {

Lorsque vous créez une *opération de chemins* **FastAPI**, vous pouvez normalement retourner n'importe quelle donnée : un `dict`, une `list`, un modèle Pydantic, un modèle de base de données, etc.

Par défaut, **FastAPI** convertirait automatiquement cette valeur de retour en JSON en utilisant le `jsonable_encoder` expliqué dans [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

If you do this, you have to make sure each one of your *path operation functions* has a unique name.

Even if they are in different modules (Python files).
