Custom Byte tracker

[ahmed.t.mohamed]

Please provide complete information as applicable to your setup.

• Hardware Platform (GPU) 1660ti
• DeepStream Version 6.0
• TensorRT Version 8.0.1
• NVIDIA GPU Driver Version (valid for GPU only) 470.82.01
• Issue Type: dlopen error: /path/to/library/libByteTracker.so: undefined symbol: _ZN2cv6String10deallocateEv

I’ve followed the repository Byte-Deepstream to created a library from the Byte Track CPP code and passed it as the custom low level tracker library for NvTracker plugin. Since the code for NvTracker is closed source, its difficult to get to the root cause of the issue.

Here is my config file
config.txt (5.1 KB)

I run this with deepstream-app -c /path/to/config.txt when I run the command I get this error message

Warning: 'input-dims' parameter has been deprecated. Use 'infer-dims' instead.
