Notebook: After uninstalling Anaconda,FileNotFoundError: [Errno 2] No such file or directory: '/Users/domore/anaconda/bin/python'

[okdolly-001]

Due to a host of other issues, I removed anaconda. However, Jupyter is still linked to the version of python in anaconda. So I uninstalled every jupyter/ipython related module and use "pip3 install jupyter."

I still encountered the same errors. I downgraded tornado since the new update doesn't work. (pip3 install tornado==4.5.3). Right now, all my packages are in "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages."

How to make Jupyter recognize that the Python I want to use is in "/Library/Frameworks/Python.framework/Versions/3.6/"?

You probably created a kernelspec which is still around. Use jupyter kernelspecs list to see where it is. The simplest solution is to delete that; Jupyter should fall back to running the kernel on the same version of Python that the notebook server is running on.

Sorry, it should have been jupyter kernelspec list. I've made that mistake before. Hopefully you've closed the issue because you figured that out and resolved the problem!
