example question

when I run the example ，it's shows ： Error: No available node types can fulfill resource request {'CPU': 1.0, 'GPU': 0.2}. Add suitable node types to this cluster to resolve this issue.
This is a problem of ray？

Hi,

If you run python main.py --config_path ../config/example.yaml and result in such an error, you might need to adjust num_actors so that the total amount of resources will not exceed your hardware configurations.

Thank you for answering my question!
but I have adjusted num_actors but it still run show ：

Spilled 2098 MiB, 10 objects, write throughput 1389 MiB/s. Set RAY_verbose_spill_logs=0 to disable this message.
(autoscaler +7s) Tip: use ray status to view detailed cluster status. To disable these messages, set RAY_SCHEDULER_EVENTS=0.
(autoscaler +7s) Error: No available node types can fulfill resource request {'CPU': 1.0, 'GPU': 0.2}. Add suitable node types to this cluster to resolve this issue.

I wonder if I need to start a ray cluster?
