+/// These tests just run on CPU execution provider for now, but could switch it to CUDA and run on GPU
+/// if the necessary work is done to setup the docker container to allow GPU passthrough to the container.
+/// See https://blog.roboflow.com/use-the-gpu-in-docker/ for an example of how to do this.
+///
+/// Can then also setup a self-hosted runner in Github Actions to run the tests on your own GPU as part of the CI/CD pipeline.
