Description

Use CodeCarbon on a SLURM cluster.

What I Did

CodeCarbon output a Warning :

[codecarbon WARNING @ 11:21:51] Unexpected output after running `scontrol show job $SLURM_JOBID` to count SLURM-available RAM. Using the machine's total RAM.
[codecarbon INFO @ 11:21:51] Energy consumed for RAM : 0.000293 kWh. RAM Power : 70.18182134628296 W
