Facing issue while converting mask_rcnn_inception_resnet_v2_atrous_coco tensorflow model to IR

[Ajay_P_Intel]

Hi,

I am trying to convert the mask_rcnn_inception_resnet_v2_atrous_coco model to Intermediate representation but getting few errors.  I have downloaded the model using downloader.py file. 

Command used to convert the tensorflow model :

C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\model_optimizer>python mo.py --input_model "C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\tools\model_downloader\public\mask_rcnn_inception_resnet_v2_atrous_coco\mask_rcnn_inception_resnet_v2_atrous_coco_2018_01_28\frozen_inference_graph.pb"

Model Optimizer arguments:
Common parameters:
        - Path to the Input Model:      C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\tools\model_downloader\public\mask_rcnn_inception_resnet_v2_atrous_coco\mask_rcnn_inception_resnet_v2_atrous_coco_2018_01_28\frozen_inference_graph.pb

Hi Ajay,

You can use the following command for successful conversion of Mask RCNN model to Intel IR:-

python mo.py --input_model <path>mask_rcnn_inception_resnet_v2_atrous_coco\mask_rcnn_inception_resnet_v2_atrous_coco_2018_01_28\frozen_inference_graph.pb --tensorflow_use_custom_operations_config extensions\front\tf\mask_rcnn_support.json --tensorflow_object_detection_api_pipeline_config <path>mask_rcnn_inception_resnet_v2_atrous_coco\mask_rcnn_inception_resnet_v2_atrous_coco_2018_01_28\pipeline.config -o <path>mask_rcnn_inception_resnet_v2_atrous_coco\mask_rcnn_inception_resnet_v2_atrous_coco_2018_01_28
