Unable to run Grafana

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.

I’m running ray 2.3.0 on python 3.8.10.
I’m having trouble running Grafana on the launcher computer.
The launcher computer is Centos.
I followed the instructions here: Metrics — Ray 2.3.0
, but I kept getting error:
Grafana-server Init Failed: Could not find config defaults, make sure homepath command line parameter is set or working directory is homepath

Can someone help? Thanks
