How to use fraction GPU in `ray.tune.Tuner`?

Hey! What is the total amount of resources you want to schedule for a single TorchTrainer?

Based on your current ScalingConfig, each Trainer/Trial will request a total of

trainer_resources + num_workers * resources_per_worker

where

trainer_resources=1 CPU
num_workers=2
resources_per_worker=0.5 GPU

So in this case, you’ll be requesting a total of 1 CPU and 1 GPU - does that match the output you’re seeing in the console output?
