TensorFlow-无效的参数:送入和获取了Reshape:0 [英] TensorFlow - Invalid argument: Reshape:0 is both fed and fetched

问题描述

有没有办法在Tensorflow中提供和获取相同的变量?如果没有，为什么不允许这样做?

Is there a way to both feed and fetch the same variable in Tensorflow? If not, why is this not allowed?

我收到此错误:

StatusNotOK: Invalid argument: Reshape:0 is both fed and fetched.

推荐答案

您不能同时获取和获取张量.解决方法是添加"tf.identity" op并获取该

You can not have a Tensor that is both fed and fetched. The work-around is to add "tf.identity" op and fetch that

tf.reset_default_graph()
a = tf.placeholder(tf.int32)
a_copy = tf.identity(a)
sess = tf.InteractiveSession()
sess.run(a_copy, feed_dict={a:1})
