Hi @lixy123 can you please share the following info. Thanks
Python 3.9.7 (default, Sep 3 2021, 06:18:44)

>>> import tflite_runtime as tflite
>>> import pycoral

I see. It shows that this is a problem of runtime library compatibility.
I downloaded the latest library file. Tell me the library version you use I can check it myself.
Can you tell me the version of the underlying library you use
Hi @lixy123 please try with the latest library versions(RuntimeVersion(14), pycoral 2.0.0, tflite_runtime 2.5.0.post1). Thanks!
get_runtime_version()
'BuildLabel(COMPILER=6.3.0 20170516,DATE=redacted,TIME=redacted), RuntimeVersion(14)'
tflite.version
report error
pycoral.version
'2.0.0'
pi@pi4:~ $ pip3 list | grep tflite
tflite-runtime 1.14.0
The reason of runtime error is that the version of tflite-runtime is incompatible with pycoral 2.0.0
I download new tflite_runtime from here, and runtime error is solved
https://github.com/google-coral/pycoral/releases/download/v2.0.0/tflite_runtime-2.5.0.post1-cp37-cp37m-linux_armv7l.whl
thanks!
