Gstnvinfer error while runnin the python apps

•Hardware Platform (Jetson / GPU): GPU- TITAN RTX
•DeepStream Version: 5.1
•TensorRT Version: 7.2.2
•NVIDIA GPU Driver Version: 460.56
•Issue Type: plugin error.

Following is the flow of my project.
I’m using TLT 3.0 for for the object detection application. The model is yolov4.
Then I pulled the docker image of deepstream-5.1-triton.
For the deployment purpose, I followed the deployment section of tlt models in deepstream:

  1. installation of Tensorrt oss for X86.
  2. TLT conveter installation
    3)Modifying config file.

But when I try to run the python apps, I get an error related to nvinfer plugin.
Below is the error that I get,

I checked the model path as well as the config file path and everything is correct.
What could be the possible way to bypass this error?

**Note: For the same procedure (Considering small changes like GPU_ARCH), the same setup works well on my PC (Quadro P1000) and jetson tx2.

Do you mean you run the same sample app with deepstream-5.1-triton docker image on two different platform?

tensorRT version is 7.2.x, it does not support TLT3.0 yolov4.
