 `ray.tune` class API is used in this example.
 
 This script is hard-coded to run on CPU only to avoid the large number of
-warnings that are emitted when GPU resources are requested but not available,
-and due to the difficulty of supressing these warnings in a way that does
-not force use of the CPU only. To enable GPU usage, comment out the
