Tensorflow Lite Export Produces Model Error

[jeffMeador]

This issue is for a: (mark with an x)

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

1. Create new project with domain General (compact) or General (compact) S1
2. Train model using Quick Training
3. Export TensorFlow Lite model
4. Test model using the sample code in this repo https://github.com/Azure-Samples/customvision-export-samples/blob/main/samples/python/tensorflow_lite/classification/predict.py

Any log messages given by the failure

This is the error provided:

Traceback (most recent call last):
  File "predict.py", line 47, in <module>
    main()
  File "predict.py", line 41, in main
    model = Model(args.model_filepath)
  File "predict.py", line 10, in __init__
    self.interpreter = tensorflow.lite.Interpreter(model_path=str(model_filepath))
  File "/Users/{username}/anaconda3/lib/python3.8/site-packages/tensorflow/lite/python/interpreter.py", line 463, in __init__
    _interpreter_wrapper.CreateWrapperFromFile(
ValueError: Model provided has model identifier '

I also tried adjusting the code to use the tflite runtime instead and it produced the same error:

Traceback (most recent call last):
  File "predict.py", line 47, in <module>
    main()
  File "predict.py", line 41, in main
    model = Model(args.model_filepath)
  File "predict.py", line 10, in __init__
    self.interpreter = tflite.Interpreter(model_path=str(model_filepath))
  File "/Users/{username}/anaconda3/lib/python3.8/site-packages/tflite_runtime/interpreter.py", line 348, in __init__
    _interpreter_wrapper.CreateWrapperFromFile(
ValueError: Model provided has model identifier '

Expected/desired behavior

Output of predicted tag

OS and Version?

macOS 10.15.7
python 3.8.12
tensorflow 2.7.0
tflite-runtime 2.5.0.post1

Thanks for the feedback.

The script expects a *.tflite model file. Please make sure to extract a tflite file from the zip file downloaded from Custom Vision service.

Thanks @shonohs that works.
