How to add python 3.6 kernel alongside 3.5 on jupyter

Question

I am trying to test some code on Python 3.6 but my system default python version is python 3.5 I have installed python 3.6 and have tried to follow the jupyter documentation to install a new python kernel

python3.6 -m pip install ipykernel
python3.6 -m ipykernel install --user

But it didn't work since it continues to show a single kernel in the menu: Python3

Has anyone managed to have both 3.5 and 3.6 in the same jupyter installation?

Answer 1

one option is to create a kernel that you can use in jupyter notebook.

you can do this inside the virtual environment:

1. Open up your terminal and enter the following line by line

   virtualenv -p python3.6 py_36_env

   source py_36_env/bin/activate

   pip install ipykernel

   python -m ipykernel install --user --name=py_36_env

   jupyter notebook

2. Then in jupyter notebook you can select the 3.6 environment (py_36_env) from the 'New' drop down menu shown above or from the 'Kernel' drop down menu within a given jupyter notebook.
