Notebook: Jupyter server cannot start

[arilwan]

I am using Macbook and was running the Jupyter server fine in the past. For nearly 3 weeks I didn't use it, and now having trouble as it isn't running.

$ jupyter notebook
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 6, in <module>
    from notebook.notebookapp import main
  File "/usr/local/lib/python3.7/site-packages/notebook/notebookapp.py", line 62, in <module>

  File "/usr/local/lib/python3.7/site-packages/tornado/httpserver.py", line 29, in <module>
    import ssl
  File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/ssl.py", line 98, in <module>
    import _ssl             # if we can't import it, let the error propagate
ImportError: dlopen(/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload/_ssl.cpython-37m-darwin.so, 2): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib

But then I can import ssl module from Python interpreter

$ python3
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 26 2018, 23:26:24)

Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
>>>

Uninstall and re-installing jupyter didn't fix it.
Any idea how to fix this?

For anyone coming across this issue, here's how I resolve it.
First uninstall openssl.
brew uninstall --ignore-dependencies openssl

The re-install it again
brew install openssl

That did not work for me. I have the same issue. Any other steps to try?

I got the same issue and that work around doesn't seem to work.
I changed the openssl version to an older one and it seems to work again.

brew switch openssl 1.0.2s
