Not able to deploy .etlt file in deepstream test app 1

Accelerated Computing Intelligent Video Analytics DeepStream SDK

I have configured my config_file.txt according to the specifications given at Integrating TAO Models into DeepStream — TAO Toolkit 3.22.05 documentation .
I am trying to deploy the detect_netv2 model with Resnet 18 that i have trained using the transfer learning toolkit. This is the error log

Now playing: sample_720p.h264

Using winsys: x11
