OpenCV bindings for Python 3 not installed about nano_build_opencv HOT 6 OPEN

Thanks for spotting this. I'd consider it still an open issue. Looks like it might be a good idea to purge any existing opencv before installing since it'll likely use the old version.

from nano_build_opencv.

Jsut a fyi, to anybody experiencing this, the above fix will work, but removing these apt package will also do the trick and possibly avoid other issues:

libopencv          libopencv-dev      libopencv-python   libopencv-samples

so sudo apt purge or sudo apt remove those and you should be fine.

from nano_build_opencv.

Ok, this did the trick:

sudo cp /usr/local/lib/python3.6/dist-packages/cv2/python-3.6/*.so /usr/lib/python3.6/dist-packages/cv2/python-3.6/

from nano_build_opencv.

unfortunately this does not the trick for me.
build_opencv.sh runs without errors (4.4 and 4.5.5), but cuda-support is only available in python2.7 not in python3.6.

sudo cp /usr/local/lib/python3.6/dist-packages/cv2/python-3.6/*.so /usr/lib/python3.6/dist-packages/cv2/python-3.6/

from nano_build_opencv.

I was able to resolve the issue by running the script below.
sudo cp /usr/local/lib/python3.6/site-packages/cv2/python-3.8/*.so /usr/lib/python3.8/dist-packages/cv2/python-3.8/

from nano_build_opencv.

Solve it for me:
ln -s /usr/local/lib/python3.6/site-packages/cv2/python-3.6/cv2.cpython-36m-aarch64-linux-gnu.so cv2.so

UPD:
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.6/site-packages
