3 modules have errors but no trace errors shown within hours

I have been struggling to reproduce the scenario of the git repo in order to capture the image from my USB camera and classify the images.
But I have been facing the problem with modules. All three modules have errors.

steps to reproduce

  1. Clone the repo.
    https://github.com/Azure-Samples/Custom-vision-service-iot-edge-raspberry-pi/
  2. Update .env file with my container registry.
  3. Build the entire solution by right-clicking on the deployment.template.json file
  4. Building process built for bullseye OS environment. It failed because of import error.
    4.1. I searched the image for my stretch version and changed from balenalib/raspberrypi3-debian-python:3.7 to balenalib/raspberrypi3-debian:stretch but building failed because default python version is 3.5.3.
    4.2. I changed the image to balenalib/raspberrypi3-debian-python:3.7-stretch.
    but building failed with the import error libhdf5.so:103.
    4.3 I added libhdf5-100 to install list of CameraCapture and changed to azure-iot-device in requirement.txt of SenseHatDisplay.
    4.4. built and pushed.
  5. Right-click on the config/deployment.json.
  6. After successful deployment, attach your USB camera to Raspberry Pi 3's hub.
  7. Check the camera status by v4l2-ctl --list-devices and check the camera image by an application.
  8. Open your IoT hub in Azure Portal and check camera-capture, sensehat-display, image-classifier-service.
  9. I tried with libhdf5-100 and python-h5py but no progress.
  10. I already submitted an issue at that git repo but no response yet.
  11. Last week I changed balena image version to Python3.5 and other errors appeared.
  12. On 21st AM I changed again to Python3.7 but build log includes 6 "load metadata" lines and one is the following:
    "load metadata for docker.io/balenalib/raspberrypi3-debian-python:3.5-stretch"
    build messages includes File "/usr/local/lib/python3.5/site-packages/cv2/init.py".
    This message was left when I missed to clear.
  13. PM I corrected numpy version no. and re-built and pushed the images and now no trace messages appear even if those 3 modules have error signal.
  14. I noticed the modules are not restarted and restarted them and found trace errors.
  15. On 23rd trace errors changed to ones with python3.7 and little change of error message appeared.
  16. On 23rd I changed installation list for trace issues
  17. On 24th restarted raspbian stretch and checked the status on Azure Portal. But I cannot find any trace errors.

Any log messages given by the failure on 24th the following are old

    Hello @Takahiro Tsuji
    Sorry for the delay in response!
    Please refer to a similar issue: please let us know over here or via email if you need further help in this matter.

    My build wasn't working as my swap space was too small. I upped it to 500 MB and it compiles now. See this link to increase your swap space: http://raspberrypi.stackexchange.com/questions/70/how-to-set-up-swap-space

    I have solved my issue. Its working for me now. python sdk needs c code for building, once I have provided that, it is working smooth now.

    I found that you need to copy the iothub_client.so file into your working directory that was generated in /azure-iot-sdk-python/c/cmake/iotsdk_linux/python/src/iothub_client.so while you were compiling it. Probably there is more elegant way to add this to python global modules, but this works.

    Hi @QuantumCache
    Thank you for the answer.

    I understand that iothub_client.so is needed but I cannot find an easy way to copy that library file to the Docker image.

    1. Should I build environment by commands in Raspbian?
    2. There is still the "libhdf5_serial.so.103: cannot open shared object file" for CameraCapture.
      I searched for the information on the web but no progress in this environment.
      I could import cv2 by cloning OpenCV4-Python source in my raspbian.
      So, I think there is a trouble in this docker environment.

    Can you provide other information?
