Inizia leggendo il traceback in context_manager_injector.py nel suo contesto, in particolare execute_with_context alle righe 209 e 339, e riproduci l'esecuzione dell'estimator TensorFlow con un'immagine Docker personalizzata. Verifica perché il job completato viene contrassegnato come non riuscito dopo l'uscita dello script principale. L'attività è completata quando il job rimane riuscito e il context manager termina senza ImportError.
