### Pydantic v1 `regex` en lugar de `pattern`

Antes de la versión 2 de Pydantic y antes de FastAPI 0.100.0, el parámetro se llamaba `regex` en lugar de `pattern`, pero ahora está en desuso.

Todavía podrías ver algo de código que lo usa:

     * All that said, don't forget that everyone should call converter.convert() instead of
     * converter.apply(), anyway. If clients use only converter.convert(), then their nullness
     * checkers are unlikely to ever look at the annotations on this declaration.
     *
     * Historical note: At one point, we'd declared this method as accepting and returning nullable
     * values. For details on that, see earlier revisions of this file.

        -  It could also be a simple python or TF utility that you could easily copy over to your own codebase. In those case, just make it your own!
        -  If you believe it should definitely be a public Keras API, please open a feature request in keras GitHub repo.
