I’m not sure if you’re currently experiencing the same problem as I’ve had, but to use repvgg_a0_person_reid_512, you have to edit the post-processing file in tappas by cloning the repo from github, change the "#define OUTPUT_LAYER_NAME "repvgg_a0_person_reid_2048/fc1"
by #define OUTPUT_LAYER_NAME "repvgg_a0_person_reid_512/fc1"
in core>hailo>libs>postprocesses>recognition>repvgg.cpp
and then recompile the file.
