【问题描述】：
周末我在 Jupyter 笔记本中运行了一些长时间的进程，但浏览器窗口在某个时候关闭了。根据this 的回答，这个过程不应该被取消，但是我得到的任何输出都会丢失。这没关系，因为我只需要访问进程中的结果对象。我的目标是连接到控制台中正在运行的内核，并从那里开始工作。根据Jupyter's documentation，我应该可以用
jupyter console --existing
但是在运行这个并挂起一分钟后，我得到以下信息
Traceback (most recent call last):
File "/anaconda/envs/py35/lib/python3.5/site-packages/jupyter_console/ptshell.py", line 323, in init_kernel_info
reply = self.client.get_shell_msg(timeout=1)

queue.Empty
During handling of the above exception, another exception occurred:

raise RuntimeError("Kernel didn't respond to kernel_info_request")
RuntimeError: Kernel didn't respond to kernel_info_request
这是因为我的长时间运行的进程仍在内核上运行，还是有其他问题？上述过程完成后，我是否可以使用上述命令按预期连接？
