我正在使用python 3.6.1，并使用Miniconda3获取jupyter笔记本请帮我内核也无法重启。谢谢！

我希望这最终会帮助我

Answer 1

“魔法数字”b'\x16\r\r\n'用于{3.5}中的.pyc文件。神奇数字最近更新为\x17时的Python broke the world。这可能与您的问题无关，但我的猜测是您的解释器是＆gt; = 3.5.3并且您的IPython内核是＆lt; = 3.5.2，尝试使用相同的模块路径。

此错误的原因是.pyc文件，缓存的python模块由计算机上以前版本的Python“编译”，解释器IPython现在使用的不能解开。

解决方案是重新安装所有内容，即获得匹配的解释器和IPython。您可以简单地删除所有.pyc个文件;它们会自动重生。

在jupyter笔记本中，内核会立即死掉
