running inference on coral edgetpu generates IndexError: index 10 is out of bounds for axis 0 with size 10

Question

I was trying to run post training int8 quantized detection model (generated through tflite and coral edgetpu compiler)using 'detect_image.py' example provided on their official website.

python3 examples/detect_image.py   --model test_data/int8_model_edgetpu.tflite   --labels test_data/tflite_label_map.txt   --input test_data/parrot.jpg   --output ${HOME}/parrot.jpg

but it's resulting into following error.

Traceback (most recent call last):
  File "examples/detect_image.py", line 109, in <module>
    main()
  File "examples/detect_image.py", line 88, in main
    objs = detect.get_objects(interpreter, args.threshold, scale)
