ROS melodic with python3 on Jetson Nano

edit

Hi All,

I am building some deep learning modules based on images on jetson nano using python3. Sadly I can not install ROS Noetic in Jeston nano since ubuntu 20.04 release is not yet available for Jetson. So im forced to use python3 with melodic. Is it good to use this method in production or is it better to port all of my scripts into python 2.7 ? The issue with python 2 is most of my python libraries supports only python 3. I have seen answers like i have to build ROS from source to install it with python 3. But i could not get proper guidelines how to do it. If anybody can suggest a solution it would be great.

Any method to bring python3 results to ROS nodes running on python 2.7 ?

Thanks

Abhishek pg
