python - 创建新的 iPython Notebook 时内核死机。

Question

我对编码还很陌生，非常感谢任何对此的帮助。它在一周前工作，现在我无法连接我的笔记本内核。我使用 anaconda 命令提示符打开 notebooke(ipython 笔记本)，它打开了 jupyter iPython 页面。我按新的 python2 笔记本。 30 秒后内核死亡(我不认为它首先连接)。这是 anaconda 命令提示符中出现的错误。我希望我能明白它在说什么。我把它交给了堆栈溢出社区的知识渊博的人。感谢您的帮助。 ~马克

Answer 1

您需要找到数据库文件并授予写入权限。该文件的格式为 history.sqlite，应该可以在 IPython 目录中找到。
