Long Boot Time and Engine Deserialization Failure in PeopleNet

Hello NVIDIA Developer Community,

I am encountering a problem with the PeopleNet model on NVIDIA DeepStream 6.4 running on Jetson AGX Orin. The issue involves an unusually long boot time and errors during the engine deserialization process. Below is the terminal output I receive when running the model:

[NvTrackerParams::getConfigRoot()] !!![WARNING] File doesn't exist. Will go ahead with default values
[NvMultiObjectTracker] Initialized
WARNING: Deserialize engine failed because file path: /opt/nvidia/deepstream/deepstream-6.4/samples/configs/tao_pretrained_models/deepstream_reference_apps/deepstream_app_tao_configs/nvinfer/../../../models/tao_pretrained_models/peopleNet/resnet34_peoplenet_int8.onnx_b1_gpu0_int8.engine open error
INFO: Trying to create engine from model files

The model eventually runs successfully but the boot time is significantly longer than expected, and these warnings are consistently appearing. The main concerns are:

  1. Deserialize Engine Failure: The system is unable to deserialize the engine from the provided file path. Is this related to compatibility issues with DeepStream 6.4 or a problem with the engine file itself?
  2. Extended Boot Time: The boot process takes an exceptionally long time, which seems unusual. Could this be related to the engine deserialization issue, or is there another underlying cause?

I have checked the file paths and configurations, and everything appears to be in order. However, I am still facing these issues. Any insights or suggestions from the community would be greatly appreciated to help resolve these problems.

Thank you for your assistance.

• Hardware Platform (Jetson AGX ORIN 64gb dev kit)
• DeepStream Version 6.4
• JetPack Version (6.0)

Which demo did you run? Could you attach your whole pipeline?

Thanks for the reply.
