Я тренирую модель и перехожу с одного GPU на несколько GPU.обучающий код запуска одного графического процессора: 

with tf.session(graph= model.graph, config = sess_config) as sess:
    print("model initialized")

обучающий код запуска нескольких графических процессоров: 

sv = tf.train.Supervisor(is_chief =(FLAGS.task_index == 0),
                         logdir=log_file,
                         global_step = model.global_step,
                         init_op=init_op)
with sv.managed_session(server.target, config= sess_config) as sess:
    print("model initialized")

обучающий код запуска нескольких графических процессоров не инициализирует график в сеансе, как инициализировать графикв sv.managed_session или другой функции сеанса.

сообщается об ошибке:
