def check_file_field(field: ModelField) -> None:
    field_info = field.field_info
    if isinstance(field_info, params.Form):
        try:
            # __version__ is available in both multiparts, and can be mocked
            from multipart import __version__  # type: ignore

    These Pydantic models define more or less a "schema" (a valid data shape).

    So this will help us avoiding confusion while using both.

### Create initial Pydantic *models* / schemas

Create an `ItemBase` and `UserBase` Pydantic *models* (or let's say "schemas") to have common attributes while creating or reading data.

## Install Gunicorn and Uvicorn

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%
```

</div>

That will install both Uvicorn with the `standard` extra packages (to get high performance) and Gunicorn.

## Run Gunicorn with Uvicorn Workers

Then you can run Gunicorn with:

<div class="termy">

```console

                name = getattr(r, "name", "unknown")
                if path is not None and not path:
                    raise FastAPIError(
                        f"Prefix and path cannot be both empty (path operation: {name})"
                    )
        if responses is None:
            responses = {}
        for route in router.routes:
            if isinstance(route, APIRoute):
