Any extra information such as torch2trt version, error log etc.

Hi @starlipernl

I was not able to install trt2torch, in order to convert the model, I used :
trtexec --onnx=yolox_s.onnx --fp16 --saveEngine=yolox_s.trt

Best Regards,
Michel.

I used the latest release of both YOLOX and torch2trt with Tensorrt version 8.6.1. When trying to run the converted model with the cpp demo script I got the following error:
Cannot find binding of given name: images.

This is because torch2trt defaults to input_0 and output_0 for the binding names. There may be a way to specific the input and output name bindings during torch2trt conversion within the trt.py file in this repo I just did not dig too much into it.

[starlipernl]

I fixed it by just reverting the yolox.cpp script back to the original input and output names (input_0, output_0)

I have already reverted this pr in #1792.
