Problem Converting Tensorflow Model (Illegal Instruction)

I used the code below to convert my model. But it does not work. 

 sudo python3 mo_tf.py --input_model /home/ls201/Desktop/veh_class_faster_rcnn/frozen_inference_graph.pb --transformations_config /opt/intel/openvino/deployment_tools/model_optimizer/extensions/front/tf/faster_rcnn_support_api_v1.14.json --tensorflow_object_detection_api_pipeline_config /home/ls201/Desktop/veh_class_faster_rcnn/pipeline.config

the output is:

Hi Maverick,

It looks like the pipeline.config file is empty, could you double check?

Also, please share additional information about the model.

  • Is it a pre-trained model or custom trained model?
  • If it's custom trained model, what base model was used for training?
  • Which version of TensorFlow was used for training?
  • How did you freeze the model?

Regards,

Jesus

I have the same problem but when I'm installing the robot_devkit, it says "Illegal instruction", this is the output:

Because of this it can't finish the process of installation of robot_devkit, specifically the problem comes out when I run the command: ./demo/rdk_install.sh , I'm following the instructions of this link: https://intel.github.io/robot_devkit_doc/pages/install.html

 

I've already have the two cameras and the neural compute stick 2,

 

the file content of the file: mask_rcnn_inception_v2_coco_2018_01_28/pipeline.config

 

is:

the only advertisement that I see is "ILLEGAL INSTRUCTION" but I haven't found any log file to see details.

 

I Hope someone can help,

 

Thanks regards .
