Trying to connect rpi5 to edge impulse - getting error code 1

Help
, ,
#1

Question/Issue:
Seem to be having basic problem using edge-impulse-linux from RPI5. Used --disable-microphone (don’t have one), and the --verbose listing seemed to recognize the camera just fine, but keep getting “Failed to initialize linux tool Capture process failed with code 1”

Project ID:
Project is called: Bar Star Vision

Context/Use case:
Just trying to connect my RPI 5 to edge impulse project

Steps Taken:

  1. [Step 1] - used --disable-microphone
  2. [Step 2] - tested camera - works with libcamera
  3. [Step 3]

Expected Outcome:
Expected my RPI5 to be connected to my edge impulse (community version) project called “Bar Star Vision”

Actual Outcome:
Failed to initialize linux tool Capture process failed with code 1

Reproducibility:

  • [ ] Always

Environment:

  • Platform: [e.g., Raspberry Pi 5]

  • snooker5@raspberrypi:~ $ cat /etc/os-release
    PRETTY_NAME=“Debian GNU/Linux 12 (bookworm)”
    NAME=“Debian GNU/Linux”
    VERSION_ID=“12”
    VERSION=“12 (bookworm)”
    VERSION_CODENAME=bookworm
    ID=debian

  • Edge Impulse Version (Firmware):

** Maybe I need to download and install firmware???
** I did not do any kind of edge impulse deployment except for:

sudo apt update
curl -sL https://deb.nodesource.com/setup_20.x | sudo bash -
sudo apt install -y gcc g++ make build-essential nodejs sox gstreamer1.0-tools gstreamer1.0-plugins-good gstreamer1.0-plugins-base gstreamer1.0-plugins-base-apps
sudo npm install edge-impulse-linux -g --unsafe-perm

when I do “edge-impulse-linux”, I get the following:

Edge Impulse Linux client v1.12.0

Should also mention that my RPI5 has an AI Hat on it as well.

I’m going to try to do connect to edge-impulse from a RPI4B in the morning and post the results. Might be just that simple.

I really do appreciate any comments anyone might have on all of this though. I’m new here and just getting started on my learning curve. Seems like really fun stuff.

Hey @snookersanders,

Can you try the following command and let me know if it works (and/or share the log)

edge-impulse-linux-runner --gst-launch-args "libcamerasrc ! video/x-raw,width=640,height=480,format=YUY2 ! videoconvert ! jpegenc"

If it doesn’t work can you share the log output of when you run libcamerasrc successfully? The more verbosity the better.
