a) Postprocess library file not found:

ERROR  vvas_xinfer gstvvas_xinfer.cpp:vvas_xinfer_postproc_init:<vvas_xinfer0>
  vvas_postprocess_create failed: <library-path> file not found
ERROR  vvas_xinfer gstvvas_xinfer.cpp:gst_vvas_xinfer_change_state:<vvas_xinfer0>
  failed to do initialization
Failed to set pipeline to PAUSED.

Possible fix - library-path in postprocess-config points to a file that does not exist. Set it to the correct path, for example:

"postprocess-config": {
    "library-path": "/usr/lib/libvvascore_postprocess_resnet50-1.0.so"
}

b) Label file does not exist:

Failed to read labels from: <label-file-path>
ERROR  vvas_xinfer gstvvas_xinfer.cpp:vvas_xinfer_postproc_init:<vvas_xinfer0>
  vvas_postprocess_create failed
ERROR  vvas_xinfer gstvvas_xinfer.cpp:gst_vvas_xinfer_change_state:<vvas_xinfer0>
  failed to do initialization
Failed to set pipeline to PAUSED.

Possible fix - label-file-path in postprocess-config points to a non-existent file. Update it to the correct location:

"postprocess-config": {
    "library-config": {
        "label-file-path": "/etc/vvas/configs/infer/imagenet-classes-1000.txt"
    }
}
