## Modelos de Pydantic

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> es una library de Python para llevar a cabo validación de datos.

Tú declaras la "forma" de los datos mediante clases con atributos.

Cada atributo tiene un tipo.

// in addition I->O. BO->BI mismatch cannot be independently created without
// breaking one of these mismatches. That gives us 4x2 tests. In addition
// condition result needs to be tensor<i1>, for which we have 3
// additional validation tests. All these tests are based on the following
// valid while

func.func @testInvalidTestValidBase(%arg0 : tensor<i32>) -> (tensor<i32>) {
  %0 = "tf.WhileRegion"(%arg0) (
    {

The named axis labels may be any single character other than those having
special meaning, namely `,.->`. The behavior of this Op is undefined if it
receives an ill-formatted equation; since the validation is done at
graph-building time, we omit format validation checks at runtime.

Note: This Op is *not* intended to be called by the user; instead users should
call `tf.einsum` directly. It is a hidden Op used by `tf.einsum`.
