yolov3-tiny model --> tensorflow .pb model --> IR, But the detection accuracy has been reduced a lot.

hi,

  My steps is :

   1. train yolov3-tiny model,   input size is 416*416;  

    2.convert  by   convert_weights_pb.py (https://github.com/mystic123/tensorflow-yolo-v3),

        the command is : python3.5 convert_weights_pb.py --class_names coco.names --data_format NHWC --weights_file yolov3-tiny_246700.weights --tiny ;  

    3.convert .pb to IR  by  mo_tf.py :

       the command: sudo python3.5 mo_tf.py --input_model /home/wrt/Download/yolo/OpenVINO-YoloV3/frozen_darknet_yolov3_model.pb --tensorflow_use_custom_operations_config extensions/front/tf/yolo_v3_tiny_changed.json --batch 1

 All the above steps are normal, but  the detection effect is very poor. 

I  only test yolov3-tiny model , it's detection effect is very well;

 Do you have any good suggestions or ideas? 

Thanks

my openvino version is   l_openvino_toolkit_p_2018.5.445
