Error Running "illustrative_example.py" in Parallel Mode: "ValueError" in "run_controller" #102

Environment:
Python Version: 3.9
Server Hardware: Two V100 GPUs
Ray Version: 2.8.0
Alpa Version: 1.0.0.dev0

Description:
While attempting to run illustrative_example.py in parallel mode on a server equipped with 2 V100 GPUs, I encountered a ValueError related to the run_controller function. The issue seems to stem from an existing actor name conflict in Ray.

I would appreciate any insights or solutions to resolve this error. Thank you for your support.
