#### Obtener el valor de *enumeración* { #get-the-enumeration-value }

Puedes obtener el valor actual (un `str` en este caso) usando `model_name.value`, o en general, `your_enum_member.value`:

/// tip | Consejo

También podrías acceder al valor `"lenet"` con `ModelName.lenet.value`.

Quando você cria um gerenciador de contexto ou um gerenciador de contexto assíncrono como acima, o que ele faz é: antes de entrar no bloco `with`, ele executa o código antes do `yield`, e após sair do bloco `with`, ele executa o código depois do `yield`.

No nosso exemplo de código acima, não o usamos diretamente, mas passamos para o FastAPI para que ele o use.

## Highlights

*   TF 2.0 delivers Keras as the central high level API used to build and train
    models. Keras provides several model-building APIs such as Sequential,
    Functional, and Subclassing along with eager execution, for immediate

    complex.
