Question

我尝试了多个端口，但均未成功：8787确实在忙于为rstudio服务。我可以重定向rstudio，但是以下工作不应该吗？

from distributed import Client, LocalCluster
cluster = LocalCluster( scheduler_port = 8785 , n_workers = 2 )

错误：

/home/ec2-user/anaconda3/lib/python3.6/site-packages/distributed/bokeh/core.py:56: UserWarning: 
Port 8787 is already in use. 
Perhaps you already have a cluster running?
Hosting the diagnostics dashboard on a random port instead.
  warnings.warn('\n' + msg)

     64             raise ValueError('too many fds')

     67             parent_r, child_w = os.pipe()
     68             child_r, parent_w = os.pipe()

我认为您需要改用diagnostics_port：

覆盖dask scheduler_port
