* The file `app/routers/items.py` is inside a package, `app/routers/`, so, it's a submodule: `app.routers.items`.
* The same with `app/routers/users.py`, it's another submodule: `app.routers.users`.
* There's also a subdirectory `app/internal/` with another file `__init__.py`, so it's another "Python subpackage": `app.internal`.
* And the file `app/internal/admin.py` is another submodule: `app.internal.admin`.

### Den `APIRouter` importieren

Jetzt importieren wir die anderen Submodule, die `APIRouter` haben:

```Python hl_lines="4-5" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
```

│   │   └── users.py     # "users" submodule, e.g. import app.routers.users
│   └── internal         # "internal" is a "Python subpackage"
│       ├── __init__.py  # makes "internal" a "Python subpackage"

    `tf.image.per_image_standardization()`
*   Move Summary protobuf constructors to `tf.summary` submodule.
