Segmentation fault when running on RASPI4 w/ Coral

[iCUE-Solutions]

Is this example supposed to also run on RASPI 4 or am I just wasting my time?

Independent of the model used I get this error.

Hello, this should works on the pi4, however we recently deprecated the edgetpu API and is actively workiong on a fix.
For now, please use my fork: https://github.com/Namburger/project-posenet

I have this same problem

Does this mean the fix is not ready? @Namburger

@andrewtvuong I am able to run this command python3 pose_camera.py --res 480x360 on RASPI4 without any error.

I don't see these lines on cmd:

Unable to init server: Could not connect: Connection refused
Unable to init server: Could not connect: Connection refused

[andrewtvuong]

Unable to init server: Could not connect: Connection refused
Unable to init server: Could not connect: Connection refused

@hjonnala I'm thinking this is due to me running the setup as headless. At the same time, I am also seeing seg fault as @iCUE-Solutions and some other folks in related issues #42 (comment)

[hjonnala]

can you share output of following command:

python3 -c 'from pycoral.utils.edgetpu import get_runtime_version; print(get_runtime_version())'

[andrewtvuong]

python3 -c 'from pycoral.utils.edgetpu import get_runtime_version; print(get_runtime_version())'
produces
BuildLabel(COMPILER=6.3.0 20170516,DATE=redacted,TIME=redacted), RuntimeVersion(14)

[hjonnala]

can you try python3 simple_pose.py and see if you are getting any segmentation fault?

[andrewtvuong]

Thanks
python3 simple_pose.py works well
python3 anonymizer.py

I am not having any segmentation issue with any script. I have python 3.7.3.

what is your
python version?
tflite_runtime version?
pycoral version?

[andrewtvuong]

Python 3.7.3
tflite-runtime 2.5.0.post1
pycoral 2.0.0

[hjonnala]

Hmm.. I have same config.. can you try without headless?

[andrewtvuong]
