Running object-detector-python example behind a proxy

[igor-rud-kr]

I’m trying to run object detection example (https://github.com/AxisCommunications/acap-computer-vision-sdk-examples/tree/master/object-detector-python) on a P3265-LV.
Both the server that I am building the example and the camera are behind a proxy. I can configure proxy settings for the docker on the server, and can execute all the steps successfully up to this one:

docker-compose --tlsverify -H tcp://$AXIS_TARGET_IP:$DOCKER_PORT --env-file ./config/env.$ARCH.$CHIP up

it displays the following message for 15 seconds
[+] Running 0/1
⠹ inference-server Pulling

and then displays the following error message:
⠿ inference-server Error 15.0s
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

This message seem to come from the docker inside the camera, not from the build server. When I ssh to the camera and execute
systemctl status sdkdockerdwrapper.service -l
the output shows that the docker service inside the camera wants to connect to the registry:

Is there a workaround for this issue? Thank you!

Hi @igor-rud-kr and welcome!

I'll move this discussion into https://github.com/AxisCommunications/acap-computer-vision-sdk-examples. The maintainers will hopefully be able to help you on your way.

Hello Igor

If docker can't pull the image from the camera, a quick fix is to upload the runtime-image manually like you do for the other two images:
docker save axisecp/acap-runtime:0.6-aarch64 | docker --tlsverify -H tcp://$AXIS_TARGET_IP:$DOCKER_PORT load

Thank you!

The error message that I am getting now is

object-detector-python-object-detector-python-1 | standard_init_linux.go:219: exec user process caused: exec format error
object-detector-python-acap_dl-models-1 | standard_init_linux.go:219: exec user process caused: exec format error
object-detector-python-object-detector-python-1 exited with code 1
object-detector-python-acap_dl-models-1 exited with code 1
object-detector-python-inference-server-1 | Server listening on 0.0.0.0:8501

Can you please point me in the right direction - how can I trace this issue?

[Corallo]

This seems an architecture missmatch, P3265-LV is an aarch64 camera, did you export the right architecture?

Yes, this was the issue, thank you!
