Model provided has invalid model identifier

[haimat]

I tried to run your model on an Ubuntu 20.04 machine. However, following your readme leads to this error:

$ python analyze.py --i a5_20190712_050100_moench.WAV --lat 49.516859 --lon 9.787153

    interpreter = tflite.Interpreter(model_path='model/BirdNET_6K_GLOBAL_MODEL.tflite')

<!', should be 'TFL3'

I have installed TF 2.7.0 via pip.
Note: Using tflite-runtime 2.7.0 leads to the very same error message.

Any ideas what could be the problem here?
