我用的是python 3.6.1，用Miniconda3获取jupyter notebook请帮帮我，内核也重启失败了。谢谢！

我希望这最终会帮助我

标签： python jupyter-notebook

【解决方案1】：

“坏幻数”b'\x16\r\r\n' 在 Python 3.5.2 之前的 .pyc 文件中使用。 Python broke the world 最近将幻数更新为 \x17。这可能与您的问题无关，但我的猜测是您的解释器 >= 3.5.3 而您的 IPython 内核是

此错误的原因是 .pyc 文件，缓存的 Python 模块由您计算机上的先前版本的 Python “编译”，IPython 现在使用的解释器无法取消腌制。

解决方案是重新安装所有内容，即获取匹配的解释器和 IPython。您可能只需删除所有 .pyc 文件就可以逃脱；它们会自动重新生成。

【讨论】：

那么我要做的是摆脱 Python 3.6.1 并获得 Python 3.5.2 版本？
不一定。我建议您摆脱 miniconda3 和 ipython 安装，并使用 Python36 的 pip3 来安装 ipython-notebook。
