When we try from our end, we get the following error:

This version of TensorRT only supports input K as an initializer. Try applying constant folding on the model using Polygraphy: https://github.com/NVIDIA/TensorRT/tree/master/tools/Polygraphy/examples/cli/surgeon/02_folding_constants

Currently, TopK with dynamic K is not supported by TensorRT.
