tensorfow object_detection faster_rcnn_resnet50 fail to model optimize.

Hi,

I trained a model faster_rcnn_resnet50 on oxford pets database, using tensorflow object detction api.

I fail to model optimize frozen_inference_graph.pb. 

C:\Intel\computer_vision_sdk_2018.3.343\deployment_tools\model_optimizer>python mo_tf.py --input_model d:\TFS\LPR\IP\MAIN\SRC\PythonProjects\TensorFlow\FreezeGraph\FreezeGraph\faster_rcnn_resnet50_pets_shay\frozen_inference_graph.pb --tensorflow_object_detection_api_pipeline_config d:\TFS\LPR\IP\MAIN\SRC\PythonProjects\TensorFlow\FreezeGraph\FreezeGraph\faster_rcnn_resnet50_pets_shay\faster_rcnn_resnet50_pets_shay.config

        - Operations to offload:        None

[ ERROR ]  Node Preprocessor/map/while/ResizeToRange/unstack has more than one outputs. Provide output port explicitly.

 

 

If I can optimize on the meta checkpoint file it would be great. Can you tell me how?

Thanks.

Hi,

I tried to convert the model you attached, but encounter another issue might caused by the Tensorflow version mismatch. Which Tensorflow version did you use to freeze the model?

Also I tried to freeze the model from my end with the "FreezeGraphDogsCats.py" but you seemed forget to add the "checkpoint" file, I only see the index, meta and data. Could you add the checkpoint inside so I can freeze from my end? Thank you.

Hi,

my tensorflow version is 1.11 on ubuntu where I train. It is tensorflow-gpu.

my tensorflow version is 1.11 on windows (I am able to train on gpu).

my windows tensorflow version is 1.12 after run the model optimizer prerequisites It is getting installed !!!

After the installation of 1.12 my training are going on CPU only.

I run the optimizer on windows So I try optimize with 1.12 I guess.

 

I will look for the checkpoint file.

Thanks.

May be I confused you.

I train on ubuntu with tf 1.11

I try to model optimize on windows with tf 1.12 (the version installed after mo prerequisets)

Thanks.

Hi, Shay,

I've tried to convert your model, but it's confused, there are multiple pb and config files, I don't know what's the right paring of them.

 

I tried the "faster_rcnn_resnet50_pets_shay.config" and "faster_rcnn_resnet50_pets_shay.pb" for conversion, it shows error as attached "ERROR_SHAY_CONFIG.PNG". The command I used is as "Command_SHAY_CONFIG.PNG"

Another try with "faster_rcnn_resnet50_pets_shay.config" and "exported\frozen_inference_graph.pb", it shows error as attached "FROZEN_PB_SHAY_CONFIG.PNG". The command used is as "Command_FROZEN_PB_SHAY_CONFIG.PNG".

I tried with the faster_rcnn_resnet50_coco_2018_01_28 with object_detection_demo_ssd_async.exe, there is no error on conversion and application running. Can you make sure your didn't change the topology with your own training?
