Question

input1 = tf.constant(3.0)
>>> input2 = tf.constant(2.0)
>>> input3 = tf.constant(5.0)
>>> intermed = tf.add(input2, input3)
>>> mul = tf.mul(input1, intermed)
>>> 
>>> with tf.Session():
...   result = sess.run([mul, intermed])
...   print result
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "/usr/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 282, in run
    raise RuntimeError('Attempted to use a closed Session.')
RuntimeError: Attempted to use a closed Session.
 

Answer 1

这个应该是中文版tensorflow上的代码，根据错误提示是使用了一个已关闭的session。也就是说result = sess.run([mul, intermed])，这句话中的“sess”是教程中上一段中的“sess”，本段代码中并没有定义sess，所以倒数第三行需要改为 with tf.Session() as sess:

Answer 2

RuntimeError: Attempted to use a closed Session.

但是代码没什么问题啊
