tell server which GPU to use

[hw-ju]

For a local machine with multiple GPUs, how to tell the MONAI Label server which GPU and how many GPUs to use?

You can use CUDA_VISIBLE_DEVICES=1,2 at individual process level..

Thanks @SachidanandAlle!
Shall I add the following to a script? Which python script shall I add it to?
import os
os.environ["CUDA_VISIBLE_DEVICES"]=1,2

[SachidanandAlle]

export CUDA_VISIBLE_DEVICES=1,2 
monailabel start_server -a <app_dir> -s <studies_dir>
