I know that opencv-python is pre-installed in jetson nano’s jetpack. But when I try “pip3 install keras-retinanet” (keras-retinanet requires opencv-python) it gives me “Error: No matching distribution found for opencv-python”. So I just can’t install keras-retinanet (and any other packages that require opencv-python) via pip.
After reading related discussions I know that pip3 can’t see opencv-python because it wasn’t installed via pip3. And I can’t install opencv-python via pip3 because there is no prebuild version for the platform.
So it feels like in order to be able to install some package that requires opencv-python via pip3 (keras-retinanet in my case) I have to make pip3 to see the pre-installed opencv. But how can I do that?
I even tried to reinstall/rebuild opencv-python from the source (as described here https://jkjung-avt.github.io/opencv-on-nano/) - but it doesn’t solve the issue - still opencv-python is not visible for pip3.
Can anyone help, please?
Thanks in advance!
