Así que tuve python 3.5 instalado en mi MacOS Sierra y obtuve la notebook jupyter instalada a través de pip3 y funcionó correctamente. Recientemente, actualicé a python 3.6 y cada vez que intenté ejecutar una notebook jupyter e iniciar una nueva notebook, se produjo el error de Kernel con el siguiente mensaje:

FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/opt/python3/bin/python3.5'
He intentado desinstalar python 3.6 e instalar python 3.5 a través de Homebrew . Pero obtuve este error cuando ejecuté jupyter notebook
zsh: /usr/local/bin/jupyter: bad interpreter: /usr/local/opt/python3/bin/python3.6: no such file or directory
No sé si hay algún conflicto entre las versiones de Python en mi macbook o Jupyter simplemente no funciona con Python 3.6
ACTUALIZACIÓN 1 :
Intenté ejecutar brew doctor y aquí está el resultado
Warning: Python is installed at /Library/Frameworks/Python.framework
Homebrew only supports building against the System-provided Python or a
brewed Python. In particular, Pythons installed to /Library can interfere with other software installs.
Sin embargo, solo Python 2.7 está instalado en ese directorio en mi sistema. Y no estoy seguro de si está en conflicto con Python 3.6
