当我提交一个小的Tensorflow培训作为单个任务时，它会启动其他线程。当我按下Ctrl+C并提升KeyboardInterrupt时，我的任务被关闭但是基础线程没有被清理并且训练继续进行。
最初，我认为这是Tensorflow的问题（不是清理线程），但经过测试，我明白问题来自Dask方面，可能不会将SIGTERM信号进一步填充到任务函数中。我的问题是，如何设置Dask以将SIGTERM信号填充到正在运行的任务中？
期望流量的示例：
本地进程 - >按Ctrl + C - > Dask调度程序 - > Dask worker - > SIGTERM信号 - >使用Tensorflow培训运行单个任务。
谢谢。
P.S如果您需要其他信息，请询问。
更新：
代码示例：
c = Client('<remote-scheduler>')
def task():
# tensorflow training
model = ...
model.fit(x_train, y_train)
training = c.submit(task)
training.result()
现在，在训练期间，当我按下Ctrl+C任务被取消，但是tensorflow线程/进程仍然存在。
更新2：ps -f -u [username]命令输出。
Dask集群（1个调度程序，1个worker，同一个服务器），没有正在运行的任务：

你可以看到没有新的东西出现。
Dask不支持将信号从客户端传播到运行任务的工作人员。
