Unable to convert Faster_Rcnn model to IR on 2019.3 version

Jump to solution

Hi there,

Am trying to convert faster_rcnn_inception_v2_coco_2018_01_28 model to IR using the below command, 

python mo.py --input_model /home/workspace/faster_rcnn_inception_v2_coco_2018_01_28/frozen_inference_graph.pb  --tensorflow_object_detection_api_pipeline_config /home/workspace/faster_rcnn_inception_v2_coco_2018_01_28/pipeline.config --tensorflow_custom_operations_config_update extensions/front/tf/faster_rcnn_support.json --output_dir /home/workspace/faster_rcnn_inception_v2_coco_2018_01_28 

And am facing this error,

Please refer to the TensorFlow Specific Conversion Parameters for OpenVINO 2019_R3.1 release that you are using.

You might have probably referred to the documentation for the latest version of OpenVINO on which --tensorflow_use_custom_operations_config is not mentioned. This is because the parameter --tensorflow_use_custom_operations_config is deprecated on the latest release and will be removed in the future releases.

Hi Aditya,

It seems like you are using --tensorflow_custom_operations_config_update parameter instead of --tensorflow_use_custom_operations_config.

Is there any specific reason? If not, please try replacing the specified parameter.

Regards,

Jaivin

Hey Jaivin,

Thanks for the reply.

So i added update because, it was not recognising the parameter as it is. So i checked with documentation over the website and added update.

Oh yeah my bad..

I specified --tensorflow_custom_operations_config instead of --tensorflow_use_custom_operations_config.

Thank you Jaivin!
