Jupyter Notebook Broken by Python 3.5

python python-3.x ipython ipython-notebook jupyter

There is a leftover kernelspec for IPython pointing to your Python 3.4.You can see existing kernelspecs with:

jupyter kernelspec list

You can install a new IPython kernelspec with

ipython kernelspec install [--user]

python python-3.x ipython ipython-notebook jupyter

I encountered the same problem as you did. I uninstalled python 3 and reinstalled it.

Then type:

pip3 install jupyter ipython

This gave me access to jupyter notebook but there was still kernel error. Then I typed:

python -m ipykernel install --user

It solved my problem.
