Jupyter Notebook error

Question

I am not able to run the notebook in my browser. It does not appear. The console is giving me the following error. I have Anaconda installed. Any help would be highly appreciated. Thanks

I uninstalled pyzmq and re-installed it:

pip uninstall pyzmq 
pip install pyzmq

This worked for me.

Note that you may also need to reinstall the Jupyter notebook to be compatible with the latest version of Python.

Anaconda 2018.3 seems very broken under Windows 10. – ivan866 Dec 03 '18 at 21:48
This worked for me - the linked question (proposed duplicate) did not. – scign Jul 17 '20 at 05:05
