Cannot interpret feed_dict key as Tensor












0















I have a list of placeholders called "enqueue_ops" and a list of methods called "feed_fns", each of which returns a feed_dict.



The queue runner of my graph is defined as:



queue_runner = feeding_queue_runner.FeedingQueueRunner(

            queue=queue, enqueue_ops=enqueue_ops,

            feed_fns=feed_fns)


However I got an error of 



TypeError: Cannot interpret feed_dict key as Tensor: The name 'face_detection/x1' refers to an Operation, not a Tensor. Tensor names must be of the form "<op_name>:<output_index>".


But why are they looking at my feed_dict keys, while my feed_dict values are tensors that they don't want to look at?



Thanks!!!

    You should add the code which raises the error, but it seems you need to add ":0" at the end of the tensor name, like "face_detection/x1:0"

In tensorflow if you want to restore a graph and use it, before saving the graph you should give your desired variables, placeholders, operations etc a unique name.



For an example see below.





W = tf.Variable(0.1, name='W')

X = tf.placeholder(tf.float32, (None, 2), name='X')

mult = tf.multiply(W,X,name='mult')


Then, once the graph is saved, you could restore and use it as follows. Remember to bundle your tensors with quotation marks. And if you are finding a value of a tensor, add :0 at the end of the tensor name as tensorflow requires it to be in "op_name:output_index" format.



with tf.Session() as sess:

    new_saver = tf.train.import_meta_graph('your_model.meta')

    new_saver.restore(sess, tf.train.latest_checkpoint('./'))

    print(sess.run('mult:0', feed_dict={'X:0': [[1,4],[2,9]]}))
