[QST]: How to use Multi-GPU computation in cugraph?

[whuLames]

What is your question?

I run the code in there for using Multi-GPU computation,but the code have the following error:
Function: _func_ucp_listener_port
args: ()
kwargs: {}
Traceback (most recent call last):
File "/root/miniconda3/lib/python3.8/site-packages/distributed/worker.py", line 3288, in run
result = function(*args, **kwargs)
File "/root/miniconda3/lib/python3.8/site-packages/raft_dask/common/comms.py", line 407, in _func_ucp_listener_port
return get_ucx().listener_port()
File "/root/miniconda3/lib/python3.8/site-packages/raft_dask/common/comms.py", line 317, in get_ucx
sessionId="ucp", state_object=get_worker()
File "/root/miniconda3/lib/python3.8/site-packages/distributed/worker.py", line 2714, in get_worker
raise ValueError("No worker found") from None
ValueError: No worker found

I dont change any word in the example code, I wan to know what cause the error and how should I do to solve it ?

Thanks !

@whuLames , Can you share the full stacktrace , this seems like a problem while starting a cluster but will need more information.
