TRT 7.1.3 - invalid results, but only on Jetpack

AI & Data Science Deep Learning (Training & Inference) TensorRT

I’ve crossposted there (Issue with TensorRT 7.1.3 on Jetson AGX - #2 by alexm5m91), but it doesn’t seem to get any love.

Meanwhile, I’m quite stuck with this: given the nature of Jetpack I can’t try if later version (say, 7.2) fixes it. I was up and down our code (and, in fact, isolated it to a standalone program), and all seems to be correct – except 100% not working on Jetson. What options do we have?
