Hi i am trying to create a face recognition program using OpenCV with the official Pi camera module v2.
The camera was working fine with my OpenCV Python programs before installing and using RPi-Cam-Web-Interface (https://elinux.org/RPi-Cam-Web-Interface) which i am using for another purpose.. though has since stopped working with OpenCV/python and all of my Python face recognition programs fail to work. I am getting "mmap: No such device" and "munmap: Invalid argument errors".
I understand and read (here: viewtopic.php?t=63276) that the even raspistill won't work when RPi-Cam-Web-Interface has started the camera, after stopping this service, raspistill works and I am able to initate the camera and take photos but it is still not working with my OpenCV.. I am getting those errors mentioned and have attached a screenshot.
I thought it may be something to do with memory or processes but I'm not sure?
Can someone please help?
