Tlt-converter tool failed

Hi, I am convertering .etlt file and it failed.
My command and error are
tlt-converter -k nvidia_tlt ./usa_pruned.etlt -t int8 -e ./usa_pruned_int8.trt -p image_input,1x3x480x640,4x3x480x640,16x3x480x640
Error: no input dimensions given

I run everything in the container and don’t know what’s wrong.

I’m afraid the usa_pruned.etlt is the LPD model. LPD model is based on TLT detectnet_c2 network.
Please refer to DetectNet_v2 — Transfer Learning Toolkit 3.0 documentation for help.
