【问题描述】：

我通过 ipython 和 anaconda 使用 python 2.7。我重新启动了计算机，尝试了不同的笔记本并尝试通过 conda 命令行更新内容。然而，每次我尝试打开笔记本时，内核都会超时，这似乎会使笔记本崩溃。有谁知道如何解决这个问题？

更新：从笔记本中重新启动内核后，终端给出了以下消息：

[E 17:45:18.308 NotebookApp] Exception restarting kernel

笔记本也给出了这个：

内核死机，自动重启失败。内核可能无法重新启动。如果您无法重新启动内核，您仍然可以保存 notebook，但在重新打开 notebook 之前，正在运行的代码将不再工作。

当我关闭并重新打开笔记本时，终端会这样说：

【问题讨论】：

您启动笔记本的终端是否有任何错误消息？

更新了问题

【参考方案1】：

我遇到了同样的问题，通过停用防病毒 (AVG) 解决了这个问题。这可能是一个安全问题...

为了重现该问题，我重新安装了 Anaconda2-4.0.0-Windows-x86_64 并在激活 AVG 时遇到了同样的错误。
