Unable to install pyrealsense2 library in Jetson Nano

Hello,

I have been trying to install PyRealSense2 in jetson nano using pip commands. I have gone through the related posts in the community and Youtube tutorials by Jetson Hack none of them helped me much in this.  I installed Librealsense2.0 SDK in jetson using jetson hacks tutorial which worked perfectly. Intel viewer was working fine with the SDK installed. 

If I want to access the camera using the python library Pyrealsense2  it is not working as expected. I need any sample tutorial or any other documentation(Sample codes) to work on this product. The issue raised only with the python while CPP and others are working fine. 

The Python version used was 2.7 

The jetpack image version is 18.04(Linux Tegra-4.9.14)

We are working on a real-time AI product using depth camera D415 and D435.
