Installed OpenCV using https://github.com/AastaNV/JEP/blob/master/script/install_opencv4.0.0_Nano.sh

installed mxnet
https://drive.google.com/file/d/1jr-kP1_zlLa9tx-GtdlBV3Nn20qRJgzY/view

As suggested https://devtalk.nvidia.com/default/topic/1049293/jetson-nano/i-was-unable-to-compile-and-install-mxnet-on-the-jetson-nano-is-there-an-official-installation-tutorial-/?#id="comment_5326170"

I am getting this error

OSError: libopencv_imgcodecs.so.3.3: cannot open shared object file: No such file or directory

Tried this https://github.com/cggos/dip_cvqt/issues/1#issuecomment-284103343

on trying this

sudo find / -name "libopencv_imgcodecs.so.3.3"

Can not find any such file

Saw

https://stackoverflow.com/questions/43152412/libopencv-imgcodecs-so-3-2-cannot-open-shared-object-file-no-such-file-or-dire

https://answers.opencv.org/question/6732/missing-shared-library/

Ran this

sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf' 
sudo ldconfig

Still i am getting the same error

Please guide, confused here

Ran this

sudo find / -name "libopencv_imgcodecs.so*"

got this

/home/user/opencv/opencv-4.0.0/release/lib/libopencv_imgcodecs.so.4.0.0
/home/user/opencv/opencv-4.0.0/release/lib/libopencv_imgcodecs.so
/home/user/opencv/opencv-4.0.0/release/lib/libopencv_imgcodecs.so.4.0
/usr/lib/aarch64-linux-gnu/libopencv_imgcodecs.so.3.2.0

/usr/local/lib/libopencv_imgcodecs.so.4.0.0
/usr/local/lib/libopencv_imgcodecs.so
/usr/local/lib/libopencv_imgcodecs.so.4.0

from where do i make mxnet point from libopencv_imgcodecs.so.3.3 to libopencv_imgcodecs.so.4.0
to avoid
