TLT Converter

I am working on Lisence Plate Recognition model on deepstream. I downloaded .etlt file as well as tlt- converter. When I try to execute ./tlt-converter, it is showing warning and I am unable to create .engine file using tlt converter.

vamsisiddharthasiddhu2041@linux:/opt/nvidia/deepstream/deepstream-5.1/samples/models/LP/LPR$ ./tlt-converter -k nvidia_tlt -p image_input,1x3x48x96,4x3x48x96,16x3x48x96 ./us_lprnet_baseline18_deployable.etlt -t fp16 -e lpr_us_onnx_b16.engine

I am enclosing screenshot of the error. Please help me to sort out this error.

I don’t see any error in the attached info.
Please run it with higher verbosity and post the log

After executing tlt converter command, it will give .engine file as output right. But, when I execute that command, i could not find any output file .

Please check if you have write access to this path. Try to chmod it.

Yeah, I tried that also, still could not get .engine file after executing tlt converter.

Can you run below?
$ ll -sh /opt/nvidia/deepstream/deepstream-5.1/samples/models/LP/LPR
