jupyter notebook running kernel in different env

Question

I\'ve gotten myself into some kind of horrible virtualenv mess. Help?!

I manage environments with conda. Until recently, I only had a python2 jupyter

Answer 1

@tschundler's solution works perfectly if your environment has already been created.

If you want to change the default kernel at the creation of your virtual environment and avoid any manual configuration, you just need to add jupyter at the end of the conda command:

conda create --name ENVNAME python=PYTHONVERSION jupyter

The correct kernel will then be used when you use ipython or jupyter notebook.
