NotFoundErrorここtensorflowセッション

Question

を復元するコードです。節約の部分は細かいようだが、復元するとき、私は次のエラーを得た：

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Tensorflowバージョン：tf.train.Saver()でVARSのリストを削除

>>> print(tf.__version__) 
1.0.1

は何とか問題を解決します。ここに作業コードがあります：

import tensorflow as tf 

filepath = "/home/kaiyin/PycharmProjects/text-classify/hello.chk" 

def save(checkpoint_file=filepath): 
    with tf.Session() as session: 
     x = tf.Variable(initial_value=[1, 2, 3], name="x") 
     y = tf.Variable(initial_value=[[1.0, 2.0], [3.0, 4.0]], name="y") 
     not_saved = tf.Variable(initial_value=[[11.0, 2.0], [3.0, 4.0]], name="not_saved") 
     session.run(tf.global_variables_initializer()) 
     print(session.run(tf.global_variables())) 
     saver = tf.train.Saver() 
     saver.save(session, checkpoint_file) 
     print(session.run(tf.global_variables())) 
     print("saved!!!!!!!!!!") 

def restore(checkpoint_file='hello.chk'): 
    with tf.Session() as session: 
     saver = tf.train.Saver() 
     saver.restore(sess=session, save_path=checkpoint_file) 
     print(session.run(tf.global_variables()[0])) 
     print(session.run(x)) 

def reset(): 
    tf.reset_default_graph() 

save() 
restore(filepath)
