【问题描述】:
使用 LSTMCell 我训练了一个模型来生成文本。我启动了 tensorflow 会话并使用 tf.global_variables_initializer() 保存了所有 tensorflow 变量。
import tensorflow as tf
sess = tf.Session()
//code blocks
run_init_op = tf.global_variables_intializer()
sess.run(run_init_op)
saver = tf.train.Saver()
#varible that makes prediction
prediction = tf.nn.softmax(tf.matmul(last,weight)+bias)
#feed the inputdata into model and trained
#saved the model
#save the tensorflow model
save_path= saver.save(sess,'/tmp/text_generate_trained_model.ckpt')
print("Model saved in the path : {}".format(save_path))
模型得到训练并保存其所有会话。链接查看整个代码lstm_rnn.py
现在我加载了存储的模型并尝试为文档生成文本。所以,我用下面的代码恢复了模型
tf.reset_default_graph()
imported_data = tf.train.import_meta_graph('text_generate_trained_model.ckpt.meta')
with tf.Session() as sess:
imported_meta.restore(sess,tf.train.latest_checkpoint('./'))
#accessing the default graph which we restored
graph = tf.get_default_graph()
#op that we can be processed to get the output
#last is the tensor that is the prediction of the network
y_pred = graph.get_tensor_by_name("prediction:0")
#generate characters
for i in range(500):
x = np.reshape(pattern,(1,len(pattern),1))
x = x / float(n_vocab)
prediction = sess.run(y_pred,feed_dict=x)
index = np.argmax(prediction)
result = int_to_char[index]
seq_in = [int_to_char[value] for value in pattern]
sys.stdout.write(result)
patter.append(index)
pattern = pattern[1:len(pattern)]
print("\n Done...!")
sess.close()
我知道预测变量在图中不存在。
KeyError: "名称 'prediction:0' 指的是一个不 存在。图中不存在“预测”操作。”
完整代码在这里text_generation.py
虽然我保存了所有张量流变量,但预测张量并未保存在张量流计算图中。我的 lstm_rnn.py 文件有什么问题。
谢谢!
