Hi Aditya,


Thanks for reaching out to us.


For your information, TensorFlow 2 SavedModel format strictly requires the 2.x version of TensorFlow installed in the environment for conversion to the Intermediate Representation (IR).


I noticed that you’re using OpenVINO™ version 2021.3.394 and Python 3.6. Please make sure you have run install_prerequisites_tf2.bat batch file separately instead of just running install_prerequisites.bat batch file. This is because running install_prerequisites.bat batch file in OpenVINO™ version 2021.3.394 will configure the Model Optimizer for TensorFlow 1 if Python version is earlier than 3.8.


If the error persists, we would like to request your model for further investigation. Please share your assets, variables, saved_model.pb files and any relevant files. You can send them privately to me if you do not want to share them in public.



Regards,

Peh
