Restez organisé à l'aide des collections
Enregistrez et classez les contenus selon vos préférences.
Convertissez les exemples d'enregistrements codés JSON en chaînes de tampon de protocole binaire.
Cette opération traduit un tenseur contenant des exemples d'enregistrements, codés à l'aide du [mapping JSON standard](https://developers.google.com/protocol-buffers/docs/proto3#json), en un tenseur contenant les mêmes enregistrements codés en protocole binaire. tampons. Le tenseur résultant peut ensuite être transmis à n'importe laquelle des autres opérations d'analyse d'exemples.

Méthodes publiques
Renvoie le handle symbolique du tenseur.
Les entrées des opérations TensorFlow sont les sorties d'une autre opération TensorFlow. Cette méthode est utilisée pour obtenir un handle symbolique qui représente le calcul de l’entrée.
