有没有一种方法可以在守护程序中启动此内核？普通的Linux语法&仍然使终端挂起，直到Ctrl-\。
$ ipython kernel
NOTE: When using the `ipython kernel` entry point, Ctrl-C will not work.
To exit, you will have to explicitly quit this process, by either sending
"quit" from a client, or using Ctrl-\ in UNIX-like environments.
To read more about this, see https://github.com/ipython/ipython/issues/2049
To connect another client to this kernel, use:
--existing kernel-56310.json
