I’m currently relying on tune.Tuner to run my experiment on a machine that has 28 CPUs and 2 GPUs. Being that I’m not the only one who has access to this machine, I’d like to restrict my experiment to a single GPU. Despite specifying with_resources(Trainer, {"cpu": 1, "gpu": 1}) both GPUs are used.…

Hi @mtt , tune.with_resources sets the resources per trial, and since you have 5 trials with 2 GPUs, Tune will schedule 2 trials at a time, each taking one of the GPUs. You can specify fractional GPUs per trial, as well as limit concurrency so you never go above some GPU usage. For example, this wi…

Thanks @matthewdeng, I create a new topic: How to use fraction GPU in `ray.tune.Tuner`?
