Pennylane multi-gpu script fails with error even there are enough gpus

Finally figured out the problem

I need to run the salloc with first with

salloc -N 1 --qos interactive --time 02:00:00 --gpus=4 --constraint gpu --account=

So all the 4 gpus are visible,

and then i run the script once the node is allocated.

srun -n 4 python dist.py
