I’m using Jetson Nano Developer Kit and trying to test TrafficCamNet.
I’ve installed the latest DeepStream 5.1 on Jetpack 4.5.1.
I’ve followed the manual and downloaded the pretrained model.
While running the deepstream-app, I’m getting the following error output:
Warning: ‘input-dims’ parameter has been deprecated. Use ‘infer-dims’ instead.

It seems that the resnet18_trafficcamnet_pruned.etlt_b1_gpu0_int8.engine file failed to be created.
I failed to find that file or convert it using tlt-converter.
Is there another way to create it?
