Tensorrt install

Description

I executed dpkg - I libnvinfer7_ 7.2.0-1+cuda10.2_ Arm64.deb and
dpkg -i libnvinfer-dev_ 7.2.0-1+cuda10.2_ Arm64.deb installs tensorrt for my NVIDIA Xavier NX, but later found that tensorrt 7.1.3 already exists, so I use Ctrl + C to terminate the installation. But when I run dpkg - l | grep tensorrt to check tensorrt, I find that libnvinfer is 7.2.0. How can I restore to 7.1.3?
The following is the output after running dpkg - l | grep TensorRT:

Hi,

Please uninstall those packages by following steps from below doc.
https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#uninstalling

Thank you.

How can I restore to 7.1.3 after uninstallation?
thank you

Please refer to archived installation guide doc,
https://docs.nvidia.com/deeplearning/tensorrt/archives/index.html#trt_7

But we recommend you to please use latest TensorRT version for better performance.

Thank you.
