        NumGPUs:

        The number of GPUs available on the system. Note that while having no
        GPUs is unlikely, consumers of this API should probably not throw errors
        if that were the case.

        GPUs:

        An array of key-pair values representing each GPU. The key named "Name" (s)
        will contain a user-facing name for the GPU, the "Environment" (as) key will
        contain an array of even number of strings, each being an environment
        variable to set to use the GPU, followed by its value, the "Default" (b) key
        will tag the default (usually integrated) GPU.
