[Xavier] ERROR: tensorrt- is not a supported wheel on this platform

While trying to install Tensorrt using https://docs.nvidia.com/deeplearning/sdk/tensorrt-archived/tensorrt-700/tensorrt-install-guide/index.html#installing-tar
Stuvk at 6th step.
the similar command for .whl file is working for 7th and 8th step.

Can someone point out the issue here.
