Extending polygraphy run to support trtexec

Introduction

polygraphy run allows you to run inference with multiple backends, including TensorRT and ONNX-Runtime, and compare outputs. This extension adds support to run inference with trtexec.

Installation

Follow the steps below to install the extension module. After installation, you should see the trtexec options in the help output of polygraphy run:

1. Build using setup.py:

   python3 setup.py bdist_wheel
   

2. Install the wheel: The wheel is installed in the dist directory. Install the wheel by running the following command

   python3 -m pip install dist/polygraphy_trtexec-*.whl \
       --extra-index-url https://pypi.ngc.nvidia.com
   

   NOTE: You may have to update the above command to install the appropriate version of the wheel

3. After the installation, you can run it on the trtexec backend by using the --trtexec flag as follows:

   polygraphy run sample.onnx --trtexec
