我正在尝试正常关闭任务 似乎在将LocalCluster与 线程而不是进程 这是我使用的代码
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary active">
<input type="radio" name="options" class="option" autocomplete="off" value="hello 1" checked> Active
</label>
<label class="btn btn-secondary">
<input type="radio" name="options" class="option" autocomplete="off" value="hi 2" /> Radio
</label>
<label class="btn btn-secondary">
<input type="radio" name="options" class="option" autocomplete="off" value="foo 3" /> Radio
</label>
<div class="showcontent"></div>这将失败，并显示以下错误
from distributed import Client, LocalCluster
cluster = LocalCluster(processes=False)
client = Client(cluster)
from dask.distributed import Variable
import time
stop = Variable()
stop.set(False)
def my_task():
while True:
if stop.get():
return
else:
print "hello"
time.sleep(10)
print "main loop exit"
future = client.submit(my_task)
# wait
stop.set(True)
如果集群的定义是这样的
