I am using Ray with SLURM and when I launch the job these logs appear in the output file of sbatch: This node has an IP address of XX.XX.XX.XXX, while we can not found the matched Raylet address. This maybe come from when you connect the Ray cluster with a different IP address or connect a container.

Is this normal or is this an indication that something is wrong and I am not properly connected?

This issue has come up before, but I don’t know if it’s an actual issue, it might just be an artifact of the Ray + SLURM setup:
