    Did you try running sudo raspi-config and enabling the camera?

  • Hi, tranks for help in my problem. Yes, the Camara is enable on the raspi-config.

    I’m using an USB camara, was detected by the Raspberry and take pictures if I use “fswebcam image.jpg” command.

    Another problem is if use images that have to compilate the face-detection-trainer, it generate the negative of pics but not generate the xml file. What could be happens?

    Regards,
    DP

    You said you’re using a USB camera, but that error tells me it’s wanting to access an rpi camera, one that gets connected to the on board camera port, not USB. You’re going to have to figure out how to change the code to use a USB camera instead.

    I have the same problem! Does someone have the solution for this problem?
    I also use an USB camera on my raspberry pi, and get the same error!

    I had the same problem. Couldn’t capture using USB webcam. Read somewhere that it does not work with USB webcam. So i got around this by taking pics (fswebcam) and selecting option 2 and giving the path to where the images were saved. That worked without any issue.
