Greetings!
I am encountering an issue when specifying the port for the worker to listen on. When using the traditional Dask Distributed with dask-worker (excluding GPU usage), I can utilize the --worker-port parameter to define this behavior. However, with dask-cuda-worker (version 23.10.0), I am unable to locate any option for this purpose, except for the --host parameter.
Consequently, when I execute the following command: CUDA_VISIBLE_DEVICES=0 dask-cuda-worker --scheduler-file scheduler.json --host 127.0.0.1:12345, it results in the following error:
warnings.warn(f'''
