Problem with google assistant on RaspberryPi

Question

When trying to run "googlesamples-assistant-pushtotalk" on my Raspberry I get this error. Anyone know how to fix this?

ImportError: /home/pi/env/lib/python3.7/site-packages/grpc/_cython/cygrpc.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: __atomic_exchange_8

Answer 1

I had the same issue with the google cloud vision library. This fixed it for me:

pip3 install 'grpcio==1.23.0' --force-reinstall

Answer 2

Another work-around is to add:

export LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1.2.0

Or whatever libatomic version you have.

e.g.:

export LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1.2.0
python3 some_script_using_grpcio.py
