I tried to convert a tensorflow trained model to IR but I am geting the follow exception

Hi Babak,
Please share more information about your model, is it an object detection/classification model, layers in use, command given to Model Optimizer to convert the trained model to Intermediate Representation (IR), and environment details (versions of OpenVINO, OS, TensorFlow, Python, CMake, etc.).
Regards,
Munesh.

Thank you Munesh for your reply,
I have solved that issue by freezing the graph and save it.
But I have new issue with unsupported layer when I ran optimizer.
I can not find any good document to explain how to create a tensorflow extension. there are just document on how o create extension for caffe
I appropriate if you could help me on this issue.
Thanks,
Babak

Hi Babak,
Please refer to the following article, “How to Convert a Model with Custom Layers in the OpenVINO™ toolkit”.

Thanks Munesh for your help,
As I mentioned before when I follow these article it goes to the following page
This article shows how to cover and register a caffe layer and there is no explanation for tensorflow layer.
I have followed it to create a tensorflow scater_nd op but the model optimizer still complaining about registering the infer function which this does not show how to do it.
Best ,
Babak

Hi Babak,
Since you are looking to implement ScatterND layer, please refer to the following 2 Pull Requests (that are already a part of OpenVINO Master branch):
Implementation of ScatterNDUpdate as part of opset4 in Model Optimizer - https://github.com/openvinotoolkit/openvino/pull/584
Implementation of ScatterNDUpdate in mkldnn - https://github.com/openvinotoolkit/openvino/pull/909

Hi Babak,
This thread will no longer be monitored since we have provided references. If you need any additional information from Intel, please submit a new question.
