具有python 3的Jupyter Notebook无法运行

Question

我无法使用Python 3打开jupyter笔记本。我安装了适用于Python 2的Anaconda和适用于Python 3的Anaconda（对于Windows均为64位）。如果我为Python 2运行jupyter notebook，则一切正常，但对于Python 3，则无法正常工作。我已经重新安装了Anaconda 3（4.2版本= Python 3.5），但这没有帮助。我还尝试了所有的google结果。从anacoda提示符运行jupyter笔记本时，我仍然收到以下错误。非常感谢您的帮助。

Answer 1

    pip uninstall pyzmq 

之后

    pip install pyzmq.

感谢Muten_Roshi。这种方法很好用。

Answer 2

我找到了一个对我有用的解决方案。在python3中重新安装pyzmq

如果你们中有人遇到同样的问题，我希望能帮助解决它。
