Tensorflow: get output blob after operation?

Question

I'm trying to get output of the blob

Part of the code:

pool5_= graph.get_tensor_by_name("pool5")
pool5_blob = sess.run([pool5_],
            feed_dict={image_placeholder: utils.image_to_batch(image)})

But I get error:

ValueError: The name 'pool5' refers to an Operation, not a Tensor. Tensor names must be of the form "<op_name>:<output_index>".

pool5 exist in [print(n.name) for n in tf.get_default_graph().as_graph_def().node] and not exist in tf.all_variables().

So if pool5 is operation how to get output blob after operation?

try putting a :0 after the name, like so:

pool5_= graph.get_tensor_by_name("pool5:0")

You can search around as to why this is necessary -- plenty written on it out there by qualified peops...
