I have followed the instructions listed here, all samples compiled well and ran without error. However, when I try the OpenCV samples, a simple
python3 -c "import cv2"
failed with the following error:
ImportError: libopencv_ml.so.4.0: cannot open shared object file: No such file or directory
ldd libopencv_ml.so.4.0 seems normal and have shown the correct paths. setupvars.sh was invoked and LD_LIBRARY_PATH and PYTHONPATH looks normal, too, at least the samples worked.
PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
I can see there is not much for "installation" as the whole VINO is already set and paths pointed by setupvars.sh. Therefore re-install wouldn't help I guess? Any idea what else could go wrong?
Thanks in advance.
Ok, I've found a solution. Don't know why LD_LIBRARY_PATH was not used so I added them to /etc/ld.so.conf and now it no longer reported the error. However, I've ran into another serious issue with this OpenCV version on my Raspberry Pi 3b+ : FATAL ERROR: This OpenCV build doesn't support current CPU/HW configuration.
