Как восстановить cstnn lstm

/ 17 декабря 2018

Я борюсь за восстановление сети, которая была обучена с помощью Cudnn Lstm.Я использую Tensorflow 1.12, Cuda 9.0 и Cudnn 7.4.Я обучил и сохранил свою сеть с помощью 

with graph.as_default():
    inputs_ = tf.placeholder(tf.float32, [None, seq_len, n_channels], name='inputs')
    labels_ = tf.placeholder(tf.float32, [None, n_classes], name='labels')
    keep_prob_ = tf.placeholder(tf.float32, name='keep')
    learning_rate_ = tf.placeholder(tf.float32, name='learning_rate')

    lstm_in = tf.transpose(inputs_, (1, 0, 2))
    cudnn_lstm =tf.contrib.cudnn_rnn.CudnnLSTM(num_layers=2, num_units=36, dtype=tf.float32)  
    outputs_, _ = cudnn_lstm(lstm_in)

with graph.as_default():
    saver = tf.train.Saver()

with tf.Session(graph=graph, config=tf.ConfigProto(log_device_placement=True)) as sess:
    sess.run(tf.global_variables_initializer())
    iteration = 1

    for e in range(epochs):
        for x, y in get_batches(X_tr, y_tr, batch_size):

            feed = {inputs_: x, labels_: y, keep_prob_: 0.5, learning_rate_: learning_rate}

            loss, _,  acc = sess.run([cost, optimizer, accuracy], feed_dict=feed)
  saver.save(sess, "checkpoints/lstm.ckpt")

Я сохранил ее в файле контрольных точек.После этого, используя код, показанный ниже, я пытаюсь восстановить переменные, такие как заполнитель ввода или точность.

graph = tf.Graph()
with tf.Graph().as_default(), tf.device('/gpu:0'):
    with tf.Session() as sess:
        saver = tf.train.import_meta_graph('checkpoints/lstm.ckpt.meta')
        saver.restore(sess, tf.train.latest_checkpoint('checkpoints/.'))  

        input = graph.get_tensor_by_name('inputs:0')
        output = graph.get_tensor_by_name('labels:0')
        pred = graph.get_tensor_by_name('pred_y:0')
        accuracy = graph.get_tensor_by_name('accuracy:0')
        keep_ = graph.get_tensor_by_name('keep:0')

Но я получаю эту ошибку "Имя 'cudnn_lstm / opaque_kernel_saveable' относится к операции не в графе". Я ничего не понимаю о непрозрачных параметрах здесь cudnn_rnn.py

Есть ли решение этой проблемы?
