我有以下代码：
a=tf.Variable(1)
b=tf.Variable(1)
with tf.Session() as session:
init_op = tf.initialize_all_variables()
session.run(init_op)
对于它，我收到了这个错误：
FailedPreconditionErrorTraceback (most recent call last)
<ipython-input-59-f8326bc9e421> in <module>()

7 init_op = tf.initialize_all_variables()
----> 8 session.run(init_op)

我不确定我在这里做错了什么。
有什么想法吗？
