Thank you. Your pull requests are welcome!

By the way, do you have any plans to add a Dockerfile?
If possible, it would be nice if you could also list the operating environment.

Sorry, my pull request is confusing to see.
If you look at the file diff, you will see the new Dockerfile image name that activated the diff written in the pull request.
And I have changed the instructions to pull my new Dockerfile.

My environment is as follows.

If you would like to know more settings of my operating environment, please tell me.

At this time, I don't know what changes you have made to your Dockerfile.

The pre-built Dockerfile may not work with some versions of the base NVIDIA driver because the CUDA version is fixed.
What if a user receiving the error would be confused by the unmodified yolox-ros-cpp/Dockerfile.

Please add a new Dockerfile or update your existing Dockerfile.
Changes only in the README without source code are unacceptable.

Sorry for the late reply.
I have updated Dockerfile.
I tried to apply the changes to "Docker-compose.yaml" as well, but I could not get confirmation that it works.
I would like to get a working confirmation including docker-compose file. However, I don't have enough time now and it is difficult to get a working check.

I followed the procedure and confirmed that it builds Dockerfile and yolox_cpp (tensorrt) correctly.
Thanks!

Thanks to check！ ❤️
