Model Optimizer error with Yolo_v3 model

I was converting another yolo_v3 model with following arguments

/opt/intel/openvino/deployment_tools/model_optimizer$ python3 mo_tf.py --input_model ~/openvino_models/models/Customer/IONETWORK/frozen_darknet_yolov3_model.pb --tensorflow_use_custom_operations_config ./extensions/front/tf/yolo_v3.json --output_dir ~/openvino_models/models/Customer/IONETWORK/ --input_shape=[1,416,416,3] --data_type FP16

and get error like this

Model Optimizer version:     2019.1.1-83-g28dfbfd

Dear SC Huang,

That is a strange error. Are you sure that you installed all the model optimizer pre-requisites ? What version of Tensorflow are you using ? My guess is that you did not perform Configure the Model Optimizer in your installation steps.

Thanks,

Shubha

Thanks Shubha,

But I'm sure I have installed those prequisites, I've successfully optimize most models downloaded from downloader.py before.

My tensorflow version is 1.12.0.

Retry after did MO config again, the Error is still the same.
