Hi, I followed the instructions written in Getting Started. However, I am seeing following errors. Can you please help?

Hi @aravindchakravarti what version of TensorRT are you using? I imagine you are using an older version.

You need to use 8.6 or newer.

Reopen the issue if you are still having issues after upgrading the TensorRT version.

@cyrusbehr : Thank you your reply. I am using TensorRT version 8.4.1.5. I will upgrade TensorRT and check.
