I followed the installation tutorial at https://www.pyimagesearch.com/2017/09/04/raspbian-stretch-install-opencv-3-python-on-your-raspberry-pi/#comment-451314 , and everything installed fine.
But I can't actually get opencv to work at all.
>>> import cv2 >>> cap = cv2.VideoCapture(0) >>> cap.isOpened() False
Any attempt to capture video or images with cv2 basically doesn't work. I don't even know where to look for logs. Can anyone tell me where to start looking?
EDIT: I'm using the Raspberry Pi camera module, which apparently needs additional drivers or something. I'll post a solution if I find one, but in the meantime I'm still listening!
