OV R1.1 Model_Optimizer [ ERROR ] Please contact Model Optimizer developers and forward the following information:

[CBell1]

Hello,

I have a problem using OpenVino R1.1 Model_Optimizer to convert inference_graph.pb file to IR.

Below the output of the error where is clearly mentioned to contact the MO developers, I can only open a request to the Support:

[ ERROR ]  Please contact Model Optimizer developers

File Attached with all details.

Please, can you support here?

Thank you

[Shubha_R_Intel]

Dear Cosma, is your *.pb a frozen one ? The error :

The node training/group_deps must have just one input

Leads me to think that maybe your model is not frozen.

Also please do a --log_level DEBUG and post the ERROR part to this forum. I think you and I have "talked before" on this IDZ thread

From where did you get this model ? Please tell me more about this model so that I may help you. Was it a Keras model that you converted to a Tensorflow Frozen pb ? If you are still trying to do Resnet 50 why not choose from one of our Model Optimizer Supported Tensorflow List ? We support Resnet50 v1 and v2.

Thanks,

Shubha

[Shubha_R_Intel]

Dearest Cosma,

Thank you for the attachments. I will definitely take a look !

Sincerely,

Shubha

[CBell1]

Dear Shubha,

during the last days, I did other tests using a new code and applying all suggestions to save TF.keras models described in the official link below:

https://www.tensorflow.org/tutorials/keras/save_and_restore_models

Before sending this new material, I would like to know if you prefer to finish analyzing the first attachements I posted few days ago.

Please, let me know

Thank you

[CBell1]

Dear Shubha,

attached the code I used to generate the mentioned .pb file, all rows are commented.

Additionally, attached, you can find the error using Model Optimizer to convert also the other file "Model_1.pb" as frozen file generated also with the simple code attached.

In both cases, the Model Optimizer doean't convert .pb to IR files.

Consider the code used and the model are really simple.

I need to find the right procedure to freeze TF Models usable with Intel Open Vino and Model Optimizer before to consider OpenVino as useful framework in production (with all steps involved: define TF Model, Training Data, freeze model and the Inference).

Thank you!

[CBell1]

Dear Shubha,

I solved the problem!

In any case, many thanks for you support and time.

Regards

[Shubha_R_Intel]

Dear Cosma,

Congrats ! Can you let me know how you solved the problem ? Please share your findings with the community if you have the time and inclination to do so.

Thanks,

Shubha

[CBell1]

Dear Shubha,

After some months the solution was simple:

I reviewed all code and cleaned some lines in the Python code used to define the model and training data!

I invested a lot of time analyzing random errors about frozen .h5 file, useless activity!

Hoping it helps

Best Regards

[Shubha_R_Intel]

Dearest Cosma,

Thank you for coming back to the forum and telling me ! Trust me, I have been where you are many many times ! Often times we learn the most from these silly errors !

I am super happy though that you were able to get up and running on OpenVino.

Please download the latest OpenVino 2019R2 which was just released today. Give it a try won't you ?

Thanks,

Shubha
