Cannot find any webcams

When I try to execute the command “edge-impulse-linux”, after entering my credentials, I get the following error message:

[GST] checking for /etc/os-release
Failed to initialize linux tool Error: Cannot find any webcams, run this command with --disable-camera to skip selection
at /usr/local/lib/node_modules/edge-impulse-linux/build/cli/linux/linux.js:442:23

I have searched and found similar topics about this. But after trying the previously proposed solutions, I still cannot make it work. When I try the “rpicam-hello” command, the camera seems to work fine.

I’m using an RPi 5 with the camera module v2.

Hi @vicinator

The error message indicates our Linux runner cannot find any webcams. If you’re not using a webcam for data collection or inference, you can run the command with the --disable-camera option to skip webcam selection.

Alternatively, ensure that your webcam is properly connected and recognized by your system.

Hi Eoin

Thank you for your reply. I’m afraid I am working on an object detection model so I will need the camera. The strange thing is that I can open the camera and take pictures on the Pi without any problems. So the error I get when connecting to Edge Impulse is quite surprising. If I use the --disable-camera option command, the Pi registers fine.

Hi @vicinator

Let me clarify and give more steps on - “ensure that your webcam is properly connected and recognized by your system.”

Did you enable the camera in the raspi-config menu?

  1. Run the following command in your terminal to open the raspi-config menu:
sudo raspi-config
  1. In the raspi-config menu, navigate to “Interfacing Options” using the arrow keys and press Enter.
  2. Inside “Interfacing Options,” find and select “Camera” and press Enter.
  3. You’ll be prompted with the question “Would you like the camera interface to be enabled?” Select “Yes” and press Enter.
  4. After enabling the camera interface, you may need to reboot your Raspberry Pi for the changes to take effect. You can do this by selecting “Finish” in the raspi-config menu and then choosing “Yes” to reboot when prompted.

Let me know if enabling the camera interface resolves the issue you’re experiencing

If this does not resolve the issue please make sure you have the correct OS on your RPI5 @rjames I might ask you to review if this is still the case:

Verify Operating System and Architecture: Ensure that you’re using the correct operating system and architecture for your Raspberry Pi 5. As mentioned in the documentation, the Raspberry Pi 4 uses aarch64, which is a 64-bit CPU architecture. If you’re uncertain about your system’s architecture, you can verify it by running the following commands:

uname -m
uname -a
getconf LONG_BIT

If the output indicates that you’re running a 32-bit OS on a 64-bit CPU (e.g., aarch64), you may encounter compatibility issues. In this case, consider switching to a 64-bit operating system to ensure proper support for Edge Impulse and its dependencies.

See more on this in our doc:

Hi, I am using raspberry pi 5 having the same issues. [cannot find webcams]

for some reason raspberry pi 5 after running “sudo raspi-config” then 3 option interfacing option we dont have camera option:
we only have 8 options; SSH, RPI connect, VNC, SPI, I2C, Serial Port, 1-wire and Remote GPIO
from preference → configuration → interface also dont have camera

I follow the setup on Raspberry Pi 5 | Edge Impulse Documentation
and do check ```
libcamera-hello --list-cameras and camera is working

if sudo apt update and sudo apt upgrade all is “0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.”

I have the same issue. I am using RPI 5 with Bookworm 64 OS and Raspberry Pi camera module 2, v2.1. I have been facing this issue for the last ten days and am stressed. I searched almost all the support on Raspberry Pi and edge-impulse but a few minutes ago I saw that edge-impulse doesn’t have support for the bookworm OS until May 8. Source: Pi 4 w/ pi camera - can't find any webcams - #6 by Eoin
So I don’t know if the support is now available, but I hope to get a response from the team. Otherwise, I have to install Bullseye OS as recommended and then try.

Is there an update to the above issue. I am running into the same issue. I don’t see the enable camera option in raspi-config but libcamera is able to detect the camera and it works.

@Shelby2024,

Can you install the gstreamer1.0-libcamera package and use the latest edge-impulse-linux >=v1.9.2 and let me know if this resolves the issue.

Note that once gstreamer1.0-libcamera is installed it hides v4l2deviceproviders, as a result it hides webcams etc… (Source)
At the moment we’re working on a better.

Hi Raul, Thanks for your assistance. Using gstreamer1.0-libcamera & new version of edge-impulse-linux works. It is able to detect the RPi camera.
