I have a problem with Ray on my macos machine. I had been using Ray with Rllib for a while but after some break, I cannot make it work again. Ray is hanging in the ray.init() function.
I have Sonoma 14.6.1 and Ray 2.4.0. I tried both conda and venv virtual environments with the same result.
My code looks as follows:
import ray
ray.init()
In the /tmp/ray/sessiong_…/logs folder I have the following files/folders:
debug_state_gcs.txt
events (contains empty event_GCS.log file)
gcs_server.err (empty)
gcs_server.out
monitor.err (empty)
monitor.out (empty)
old (empty)
The debug_state_gcs.txt file ends with lines:
Event stats:
RaySyncer.deadline_timer.report_resource_report - 71784 total (1 active), CPU time: mean = 37.238 us, total = 2.673 s

InternalKVGcsService.grpc_server.InternalKVGet - 1 total (0 active), CPU time: mean = 36.000 us, total = 36.000 us
GcsInMemoryStore.Get - 1 total (0 active), CPU time: mean = 16.000 us, total = 16.000 us
I would be grateful for any help investigating and solving the problem.
