Hi,
I opened a new issue and they helped me out here: Can't execute TRT engine on Jetson Nano - #2 by naisy
I was able to make it run. Sadly now I have JetPack 4.6.1 installed and I can’t go back to 4.6 because my access to the Jetson is limited and I need it to work.
Anyway, thanks for everything. You can close the issue if you want.
