Métodos públicos
Salida pública <T> como Salida ()
Devuelve el identificador simbólico del tensor.
Las entradas a las operaciones de TensorFlow son salidas de otra operación de TensorFlow. Este método se utiliza para obtener un identificador simbólico que representa el cálculo de la entrada.
Método de fábrica para crear una clase que envuelve una nueva operación de CholeskyGrad.
