model optimizer issue

I got pb file from yolo model, and tried to convert it to IR using mo_tf.py script.

But it shows following error.

 

python3 mo_tf.py --input_model ~/Documents/tensorflow-yolo-v3/yolov3_model.pb --tensorflow_use_custom_operations_config extensions/front/tf/yolo_v3.json --batch 1

Hi Luy,

Is your model a custom model or is it pure yolov3? If its possible please share your .pb model so we can attempt to convert it to IR format, you can send me a private message in case you don't want to share it publicly.

Also, from the error message it looks like you are using and older version of OpenVINO, I'd suggest to try the latest release and see if the problem persists.

 

Regards,

Luis
