*  `tf.image`
    * Adds JPEG XL support in decode_image.

### Bug Fixes and Other Changes

* `tf.data`
    * Adds `NoneTensorSpec` to the public API so that `None`s in `element_spec`
      can be identified via `isinstance(..., tf.NoneTensorSpec)`.

## Créer une instance { #create-an-instance }

Nous pouvons créer une instance de cette classe avec :

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[18] *}

Et de cette façon, nous pouvons « paramétrer » notre dépendance, qui contient maintenant « bar », en tant qu’attribut `checker.fixed_content`.

## Utiliser l'instance comme dépendance { #use-the-instance-as-a-dependency }
