Hi all

I am trying to run a project that involves the use of a camera. I am able to connect to the server as shown below :
edge-impulse-linux
Edge Impulse Linux client v1.4.8

But when I rrun the command “edge-impulse-linux runner”, I am getting thi s error message:

Can anyone help me? from reading other posts there seems to be a problem with the camera, but I tried it once before and it worked, so I am genuinely stuck

Hi @someguy

Thanks for the report, we are looking into it. Can you please try the steps listed here:

CSI Camera not found in remote dashboard

Question/Issue: I cannot connect my new RPi4 via edge-impulse-linux login, because at the terminal login my (ordinary ribbon-cable) camera is not detected, and the connection fails. It does see USB cameras, but I can’t use them for my image classifier. Could not find this topic on the forum. Are generic ribbon cams supported in the EI Dashboard for data and testing? Thank you Project ID: T3068 Context/Use case:

And update there with your findings, Raul on that thread has a fix in progress but it would be helpful to have this validated by a user with the same environment, and error before releasing.

If we can keep the same issues together on existing threads it really helps in identifying bugs early, as we have many reports that typically are the result of environmental setup issues.

Thanks again,

Eoin

Hi @Eoin
Per Raul’s suggestion I rolled back the OS (bullseye), but got the same error in the Edge Impulse daemon (camera not found). Apologize for the pause - other priorities. This project still ongoing so any resolution will be helpful.
Thanks,
Rich

Hi @tambourello,

A few things that can be checked:

• Does the camera work when running the libcamera-hello?
• Can you run the linux cli with --verbose and post the output? Does gstreamer complain about missing libcamerasrc?
• Do you have the libcamera gstreamer plugin ? You can install it with sudo apt-get install gstreamer1.0-libcamera
