Docker added --gpu flag to docker run command #21

Docker has added an explicit --gpus flag to the docker run command. Not sure if this is any better than the way we are currently separating gpus, but it is worth looking into. https://docs.docker.com/engine/reference/commandline/run/#access-an-nvidia-gpu

The output of docker version is:

The docker documentation indicates that the --gpus flag should be available for docker engine version 19.03, but I can't seem to find the --gpus option when viewing the output of docker run --help?

I think found something once that said the --gpus flag was only available in API version 1.40 or higher. I have no idea where I found that information though haha. I also have no idea how to update that.

That makes sense. We have API version 1.39 as indicated above. However, it also states that it was downgraded from version 1.40. I wonder if that was done because of a conflict with some other dependency?
