IR v6 not supported

[goh__richard]

Hi

I have an existing custom model    model.xml .

When I run it on latest security_barrier_camera_demo , I get the following error

[ ERROR ] The support of IR v6 has been removed from the product. Please, convert the original model using the Model Optimizer which comes with this version of the OpenVINO to generate supported IR version.

How can I convert this model to a version supported by my version?

Hi Richard,

Thanks for reaching out to us.

There is no way to upgrade previously converted Intermediate Representation (IR).

Please re-convert your original model into IR with the current Model Optimizer of OpenVINO™.

Hi Peh,

Thanks.

1. how can i convert the model below?

2. Can this IR Model be converted to another "model" and then converted back to IR?

Thanks

Hi Richard,

From the error message, it shows that Model Optimizer cannot infer shapes or values for the specified node. Please ensure that you specify the correct input shape for your model.

If possible, please share your model with us to further investigate and better assist you in IR conversion.

Regards,

Peh

thanks.

Please download model  here http://anpr.optasia.com.sg/download.cgi?f=graph.pb

thanks for your help

[Munesh_Intel]

Hi Richard,

We are also getting the same error as you.

We would like to obtain more info about your model, as follows:

• The source repository of the model.
• Did you retrain the model? If yes, which TF version did you use?  

Regards,

Peh

[goh__richard]

Hi Peh

Thanks for your assistance

Is the following info helpful?

2019.3.376

ssd_detector

vlp

[Munesh_Intel]

Hi Richard,

Are you using the training extension from the following repository?

https://github.com/malikaoudjif/training_toolbox_tensorflow/blob/master/models/ssd_detector/README.md

This training extension from 2018 is outdated and not compatible with the latest version of OpenVINO.

If yes, then we would suggest you retrain your model using our latest training extension.

The datasets (vlp_test, bitvehicle, etc.) are available here.

https://github.com/openvinotoolkit/training_extensions/tree/master/data

For your use case, you can use MMDetection, which is an Object Detection and Instance Segmentation toolbox.

The basic tutorials for MMDetection are available here:

Thanks for your assistance.

>If yes, then we would suggest you retrain your model using our latest training extension.

May we know where to find the lastest training extension?

Thanks

[goh__richard]

HI

Thanks for your help.

It seems MMdetection is for python?

Is there similar for cpp?

Thanks

[goh__richard]

Hi

We are usinsg security_barrier_camera_demo for the above model.

For this program, how can we train the same model for it if not using ssd/vlp?

thanks

[Munesh_Intel]

Hi Richard,

We don’t have a similar training extension in C++.

Our training extensions have been updated and enhanced.

You can retrain your custom model by following the steps mentioned in the example here:

3: Train with customized models and standard datasets

The prerequisites and installation steps for MMDetection are available here:
