So I tried to fix my Jupyter notebook (it wasn't letting me import libraries), however, it appears I made things worse. Now whenever I start the notebook, the kernel starts, and then instantly dies. The error I get is below:

Or should I just go about a full uninstall and reinstall? Also, how do I go about doing so? When I do sudo pip uninstall jupyter, it doesn't seem to work.
pip uninstall jupyter-core jupyter-client notebook, but yeah, still bad idea unless you are in a virtualenv.ipynb is not trustedmeans it was digitally signed somehow
