Question

运行Linux Mint 13 Maya（64位）

在epd 7.3.2（学术）和Canopy上，当运行笔记本时，内核会定期死掉。我得到一个允许我重启内核的弹出窗口。我在终端窗口看到了这个：

Answer 1

您的问题与https://github.com/ipython/ipython/issues/2824类似。它可以在较新的IPython版本中解决，或者你可以在那里找到建议。

Answer 2

使用最新的Enthought Canopy Express（ex-EPD Free）我遇到了同样的问题。为了解决这个问题，我刚刚将IPython升级到了0.13.1，并且它停止了死亡，并且开始像我的其他（标准自己制造的）安装IPython一样顺利运行。

我有类似的问题，当我重新启动系统时，为了导入像sklearn或者skimage之类的东西，它会给予像＃34这样的按摩;内核似乎已经死了。它会自动重启。＆＃34;然后它根本没有重启，我不得不重新安装顶篷，然后安装我需要的所有包有没有办法修复树冠然后重新安装？为什么这种情况最常发生
