I am using Docker image from nvcr.io/nvidia/deepstream:5.0.1-20.09-devel

• Hardware Platform (Jetson / GPU) GPU
• DeepStream Version 5.0.1
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only) 11.1
• Issue Type( questions, new requirements, bugs) questions
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

I am running a simple pipeline in python which reads a mp4 file, runs inference and tracking and saves results to an output file. I can’t understand why, when tracker is activated , this null label appears:

Where is this coming from? Can’t find any help with this

I see, my labels.txt path was wrong so the osd couldn’t load labels properly. Anyway just modified object metadata and add labels there as in https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/blob/master/apps/deepstream-test4/deepstream_test_4.py#L264
