Issue Description

There are a few open or closed issues in this forum for partial instructions on how to ensure compatibility of pyrealsense2 on a Jetson device, either Nano or TX2, either python2 or 3. For instance here, or here; many threads provide pieces of solutions. After hours struggling and trying to use that guidance, my team is still struggling either with cmake configuration, , with usb detection problems, or even with numpy errors. We still can't get the L515 working.

For people that want to install it on a freshly flashed Jetson nano device (e.g. JetPack 4.5), and are not Linux/system engineers, can someone provide a comprehensive and reproducible guide on all instructions on a new device, to run the SDK in python3?

Hi @agenis

There has been some updates with regards to Python in general that I think may help:
