Unable to run conversion for a tensorflow "saved_model" format for inferance

I have a problem running when trying to use the convertion script from the OpenVINO toolkit.

 

I am running the script with the following parameters:

mo_tf.py --saved_model_dir ./test/saved_model --transformations_config /opt/intel/openvino_2021/deployment_tools/model_optimizer/extensions/front/tf/ssd_support_api_v2.4.json --tensorflow_object_detection_api_pipeline_config ./test/pipeline.config --data_type FP16

 

End it ends up with an error :

"Exception occurred during running replacer "ObjectDetectionAPIOutputReplacement" (<class 'extensions.front.tf.ObjectDetectionAPI.ObjectDetectionAPIOutputReplacement'>): Graph contains 1 node after executing <class 'extensions.front.tf.ObjectDetectionAPI.ObjectDetectionAPIOutputReplacement'>. It considered as error because resulting IR will be empty which is not usual"

I want to specify that I've used in the past the script with success with the same pipeline config file.

I will attached the pipeline config and a screenshot of the error.

Hi Petrica,

Thanks for your patience.

 

I have successfully converted the model into IR with the following command:

mo --saved_model_dir=saved_model --tensorflow_object_detection_api_pipeline_config=pipeline.config --framework=tf --reverse_input_channels

Could you please try it and see if you are able to convert the model into IR?

Wan

Hi Petrica,

Thanks for reaching out to us.

 

May I know which version of the OpenVINO™ toolkit are you using? For your information, OpenVINO™ Development Tools version 2022.1 is available now. You may refer to here to install the latest OpenVINO™ Development Tools and convert your model again.

 

On another note, if you still facing issue when using the latest OpenVINO™ Development Tools to convert your model, could you please share your model with us for further investigation?

 

 

Regards,

Wan
