尝试在Jupyter实验室中使用本地群集初始化客户端，但挂起。 python 3.5和jupyter lab 0.35会发生这种情况。
import dask.dataframe as dd
from dask import delayed
from distributed import Client
from distributed import LocalCluster
import pandas as pd
import numpy as np
import json
cluster = LocalCluster()
client = Cluster(cluster)
client
工具的版本：
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
jupyter实验室版本是
pip list |grep jupyter
jupyter 1.0.0
jupyter-client 5.2.3
jupyter-console 6.0.0
jupyter-core 4.4.0
jupyterlab 0.35.3
jupyterlab-server 0.2.0
早期版本
pip list |grep dask
dask 0.20.0
怎么了？
编辑：尝试初始化客户端时终端上没有异常 中断内核具有以下例外情况： 内部jupyter：
