Couldn't find tensorrt version

I built a tensorrt engine file with Tensorrt, and I want to run it on Jetson Nano with python3.6. But I got this error message:

[TensorRT] ERROR: The engine plan file is not compatible with this version of TensorRT, expecting library version 5.1.6 got 5.1.5, please rebuild.

I know that I should rebuild my model with version But I couldn’t find the tensorrt version on the official download website.

How can I install tensorrt on Jetson Nano

The environment of my PC is :
Ubuntu 16.04 , x86_64


YES. Please noticed that TensorRT engine is not portable since it includes hardware level optimization.
You will need to recompile the TensorRT engine on the Nano directly.
