I would have thought this would be covered by the nvidia-tensorrt package, but I could be wrong.

Anyone got any ideas of what to try?

Thanks

seems same with below.

It turns out for my system, Jetpack 4.6 comes with Tensorrt 8, libnvinfer.so.7 doesn’t exist with this package version. I decided to downgrade to Jetpack 4.5.11 which comes with Tensorrt7, libnvinfer.so.7, and the demo application works as expected.

Glad to know you fixed your issue.
