I have a Jetson Orin development kit and just upgraded to Jetpack 5.1

Now when I attempt to import tensorrt in python, it fails with the error “ModuleNotFoundError: No module named ‘tensorrt’”

Hi,

Please try the following command to install the python binding for TensorRT.

```auto
$ sudo apt install python3-libnvinfer*

```

We are checking why the python binding is not installed by default with our internal team.  
Will share more information with you later.

Thanks.
