export encoder from onnx to tensorrt

I got error when export encoder onnx model to tensorrt, here is the error
"""
This version of TensorRT does not support dynamic axes." failure of TensorRT
"""
I tried the latest version of tensorrt and did not use the parameter dynamic_axes, but it did not work.
Anyone has successful experience about this?

The issue names no files, tests, or entry points. Start by reproducing the encoder ONNX-to-TensorRT export with and without dynamic_axes, then compare the TensorRT version and export inputs involved. Done means identifying a supported export path or documenting the specific incompatibility.
