Issue with GPU

[JTPlayzYT]

I am having an issue using my GPU, it gives an error on start saying "Detecting local GPU Information failed! Unrecognized function or variable 'gpuDeviceCount'"

Likely, your Matlab version is not supporting the 'gpuDeviceCount' function.

From my understanding, it seems like the issue is with a missing toolbox rather than a version problem. Using the mathworks/matlab-deep-learning docker image may be helpful.
