我正在使用python 3.6.1，并使用Miniconda3来获取jupyter笔记本，请帮助我，内核也无法重启。 谢谢！

希望这对我有帮助

Answer 1

在python 3.5.2之前的.pyc文件中使用了“错误的魔术数字” b'\\x16\\r\\r\\n' 。 最近魔术数更新为\\x17时，Python 打破了世界 。 这可能与您的问题无关，但是我猜测您的解释器> = 3.5.3，而IPython内核是<= 3.5.2，试图使用相同的模块路径。

导致此错误的原因是.pyc文件，由计算机上的早期版本的Python“编译”的缓存的python模块，IPython现在使用的解释器无法释放。

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文件就可以摆脱； 它们会自动重新生成。
