Hi,

```auto
ModuleNotFoundError: No module named 'common'

```

The error indicates it cannot find the required python module.  
Would you mind updating it to the absolute path to see if it helps?

```auto
import sys
sys.path.append('[deepstream_python_apps/root]/apps/')

```

Thanks.

Hi,

Have you built it from the source?  
You will need to do this after reflashing the Xavier.

Below are the instructions for compiling for your reference:

> **[TensorRT/python at main · NVIDIA/TensorRT](https://github.com/NVIDIA/TensorRT/tree/main/python)**
>
> NVIDIA® TensorRT™ is an SDK for high-performance deep learning inference on NVIDIA GPUs. This repository contains the open source components of TensorRT. - NVIDIA/TensorRT

Thanks.
