Benchmarking TLT YOLOv3

Hi Team,
I have been following the below mentioned github repo:
(GitHub - NVIDIA-AI-IOT/deepstream_tlt_apps: Sample apps to demonstrate how to deploy models trained with TLT on DeepStream)
I have got the TLT Models from:
[https://nvidia.box.com/shared/static/i1cer4s3ox4v8svbfkuj5js8yqm3yazo.zip]

Below are the details:
Environment:
Device: Tesla T4
Cuda Version: 10.2
Tensorrt version: 7.0
Docker image: docker pull nvcr.io/nvidia/deepstream:5.0-20.07-triton

Command:
./ds-tlt -c /opt/nvidia/deepstream/deepstream-5.0/samples/deepstream_tlt_apps/configs/yolov3_tlt/pgie_yolov3_tlt_config.txt -i /opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.h264 -b 2

Output Error:
WARNING: Overriding infer-config batch-size (1) with number of sources (2)
Now playing: /opt/nvidia/deepstream/deepstream-5.0/samples/deepstream_tlt_apps/configs/yolov3_tlt/pgie_yolov3_tlt_config.txt

I have also followed:
(deepstream_tlt_apps/TRT-OSS/Jetson at master · NVIDIA-AI-IOT/deepstream_tlt_apps · GitHub)

But still the error persists:

Please suggest a way, how can I benchmark yoloV3 Model?

Please refer to TLT-deepstream sample app problems : I found thatFRCNN, SSD , DSSD , RetinaNet and Detectnet_v2 can run successfully, but Yolov3 can’t - #21 by hyperlight .
