上周末，我在 Jupyter 笔记本上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。根据这个答案，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 的文档，我应该能够做到这一点

jupyter console --existing

但是在运行这个并挂了一分钟之后，我得到了以下信息

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)
  File "/anaconda/envs/py35/lib/python3.5/site-packages/jupyter_client/client.py", line 77, in get_shell_msg
    return self.shell_channel.get_msg(*args, **kwargs)
  File "/anaconda/envs/py35/lib/python3.5/site-packages/jupyter_client/blocking/channels.py", line 57, in get_msg
    raise Empty
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？当所述过程完成后，我是否可以使用上述命令按预期连接？

解决方案*鼓声*：

我只需要跑步

jupyter console --existing

在我运行的同一目录中

jupyter notebook
