Problem with Python Version And Jupyter Notebook

Question

So I created a python 2.7 env "gdsenv" using anaconda:

Then I installed the jupyter kernel:

...so far it seems good.

The problem is that if I open jupyter-notebook, I don't get python 2.7 option (I have python 3.5 installed on another env):

Why is that and how can I fix that ?

Answer 1

See if you can install an ipython kernel for python2.

I don't have anaconda installed, but here's how it works for a virtual environment created with python2 -m virtualenv jupyter-test:

1. Install jupyter:
   python2 -m pip install jupyter
2. Install ipython kernel for python2:
   python2 -m pip install ipykernel
python2 -m ipykernel install --user
3. Start jupyter not[![ebook

You should now be able to create a python2 kernel:
