Ray 2.10: CPU / RAM / GPU usage not correctly displayed on Windows 11

How severe does this issue affect your experience of using Ray?

  • Medium: It contributes to significant difficulty to complete my task, but I can work around it.

Dear all,

question to the community if you also face following behavior:

Using Rllib Python API, the localhost ray dashboard does not show any CPU, memory or GPU usage stats during execution. This is strange, as in the same line it is reported that 2 CPU cores and 0.3 GPU cores are used by the RolloutWorker.

Windows version: 10.0.22631 Build 22631 (a.ka. Windows 11)

What Ray version are you on? A repro script would be helpful here too; can you please cut a ticket on our Github and label RLLib plus ‘triage’?

Ok, @Sam_Chan , I opened [Dashboard][RLlib] Ray 2.10: CPU / RAM / GPU usage not correctly displayed on Windows 11 · Issue #44604 · ray-project/ray · GitHub which also covers repro script.
