AttributeError: 'Interpreter' object has no attribute '_get_full_signature_list'

Description

I can't get the detect_image.py example to run. I've tried using different models, but I keep getting an error about the signature list.

Please check the tflite runtime version and if its not 2.5.0post1, please uninstall and install it again with the instuctions at: https://coral.ai/software/#debian-packages

hemanthj@:~$ python3 -c "import tflite_runtime as tflite; print('tflite runtime vesrion:', tflite.__version__);import pycoral; print('pycoral version:', pycoral.__version__)"
tflite runtime vesrion: 2.5.0.post1
pycoral version: 2.0.0

Thanks for that! While not technically an install issue, it led me to find that I had a copy of tflite_runtime hiding in /usr/local/lib/python3.8.
