What are input and output node names in inception v3 with slim library?

Question

I retrained inceptionV3 model on my own data using Tensorflow slim. Below files are generated after training :-

graph.pbtxt, model.ckpt, model.meta, model.index, checkpoint, events.out.tfevents

I want to freeze the graph files and create a .pb file. I don't know what is input node and output node in inception v3. And using Tensorboard is complex for me.

What are the input/output nodes in inceptionV3?(in slim/nets) OR how can I find the input/output nodes ?

OS : window 7

You can find the input and output name from the .pbtxt file. [This may help](https://stackoverflow.com/a/43535500/5695391) — Bibhu Pala, May 30 '18 at 06:29
@BibhuPala Yes I know that using tensorboard but It's so complex — Chansu Lee, May 30 '18 at 07:51
@ChansuLee If you dont have a .pb file, where have you stored the trained model weights ? — Akash Goyal, May 30 '18 at 07:58
@AkashGoyal if I retrain model, I get model.ckpt, graph.pbtxt files. I think weight stored ckpt file. — Chansu Lee, May 30 '18 at 08:18
@ChansuLee So, do you have a .ckpt file? Can you mention all filenames that are generated in your training — Akash Goyal, May 30 '18 at 08:54
@AkashGoyal model.ckpt-100000 / checkpoint / events.out.tfevents / graph.pbtxt — Chansu Lee, May 30 '18 at 09:02
Please update the same in your question also. I am writing answer for you — Akash Goyal, May 30 '18 at 09:25
You should mention all the required details in your question. So, edit your question and mention the files that are generated by training. And also mention the steps that you have taken till now for your task. — Akash Goyal, May 30 '18 at 09:35

(A). If you will make it to bottom of this link. You would find this somewhere(specific to inceptionV3) :

input_layer=input
output_layer=InceptionV3/Predictions/Reshape_1

(B). Another way is to print all tensors of the model and get input/output tensor

from tensorflow.python.tools.inspect_checkpoint import print_tensors_in_checkpoint_file
ckpt_path="model.ckpt"
print_tensors_in_checkpoint_file(file_name=ckpt_path, tensor_name='', all_tensors=True, all_tensor_names=True)

(C). If you need to print tensor names of .pb file. You can use this simple code.

Check what would work for you.

@ChansuLee Have you got a satisfactory answer or have any doubts? – Akash Goyal May 31 '18 at 05:25
Thanks to update my question ! I will try this solution. – Chansu Lee May 31 '18 at 07:58
Now I know output node but After freezing, I should do optimize for inference. I got error when i do optimizing. "The following input nodes were not found <'input'>" – Chansu Lee May 31 '18 at 08:10
You should first test your freezed model. Then go for optimization. Also it is easy to print the tensors(operations) of a .pb file. So, you can print them and verify input node – Akash Goyal May 31 '18 at 08:20
How can i print tensor with .pb file? – Chansu Lee May 31 '18 at 08:58
Is the first line in the result of the code the input node? – Chansu Lee May 31 '18 at 11:28
It depends on your model structure. Check first few nodes and pick one that works for you – Akash Goyal May 31 '18 at 12:09
Thanks for helping me – Chansu Lee Jun 01 '18 at 05:53
