Pyrealsense2 & opencv throw Illegal instruction ( core dumped )

Hey guys I recently got the Jetson so I began installing some packages to get to work with the intelrealsense 435 camera. Here is a photo of my nano specs

The whole point of these installs is to work with the following script but this is what I get

For cv2

For pyrealsense2

When I try to run them separetely on the terminal I get this subsequently

Can someone point out to me what the errors are and how to fix them please ? I would kindly appreciate any feedback.

Thanks
