Running mo_tf RCNN error

Hello,

I have trained an inference graph using RCNN faster_rcnn_resnet50_coco_2018_01_28 downloaded from https://docs.openvinotoolkit.org/latest/_docs_MO_DG_prepare_model_convert_model_Convert_Model_From_TensorFlow.html

and when i try using the model optimizer with the following command " python mo_tf.py --input_model=D:/Software_development_tools/tensorflow/models-master/research/object_detection/inference_graph/frozen_inference_graph.pb --tensorflow_use_custom_operations_config C:/IntelSWTools/openvino_2019.1.133/deployment_tools/model_optimizer/extensions/front/tf/faster_rcnn_support.json  --tensorflow_object_detection_api_pipeline_config D:/Software_development_tools/tensorflow/models-master/research/object_detection/inference_graph/pipeline.config --reverse_input_channels --data_type=FP16
 "  i get the error

I have spend days trying to solve this issue with no luck and i would be very thankful if someone can help me out please. I have attached my config file.

 

Thank you for your time!

Dear Stankov, Stanko,

This is a known bug which several customers have experienced (it has to do with custom trained Tensorflow Object Detection API models). Sorry for the inconvenience ! Stay tuned on this forum for the progress.

Sincerely,

Shubha

Dear Stankov, Stanko,

I have a fix for you. Unzip the attached and drop the *.json files into C:\Program Files (x86)\IntelSWTools\openvino_2019.1.133\deployment_tools\model_optimizer\extensions\front\tf (or the Linux variant). Try it again. This time it will work !

Thanks,

Shubha

I am also training the a faster RCNN network on the OxfordIII pets dataset. Is there anythin that I can do?

Hello, I am also having the same error when trying to optimize a trained faster RCNN model. I trained the faster RCNN model on the OxfordIII Pets Dataset using the Tensorflow Object Detection API and with the pre-trained faster RCNN 101 Coco model from your downloads site. I've also tried to use the newer .json file that was kindly provided but still no success. Maybe you have an Idea? I attached my log (temp.txt).

Dear Stangier, Lorenz,

Can you try upgrading to Tensorflow 1.13 and try again ?

Please report back here with your results.

Thanks,

Shubha
