You can use a virtualenv for your IPython notebook. Follow these steps:
For the version of Python that you want in your virtualenv, get the versions of the following packages that are installed by default:
so for example, if you want to use Python 3.6, run the following and note the versions:
pip3.6 show tornado pip3.6 show ipykernel pip3.6 show prompt-toolkit
Install the packages with the appropriate versions into your virtualenv:
workon my-virtualenv-name # activate your virtualenv, if you haven't already pip install tornado==<tornado version from above> pip install ipykernel==<ipykernel version from above> pip install prompt-toolkit==<prompt-toolkit version from above>
so, for example, if the versions shown were 6.0.3, 5.1.3 and 2.0.10 respectively, run:
workon my-virtualenv-name pip install tornado==6.0.3 pip install ipykernel==5.1.3 pip install prompt-toolkit==2.0.10
Note: The order in which the packages are installed is important. Make sure you install prompt-toolkit last.
You should now be able to see your kernel in the IPython notebook menu:
Kernel -> Change kerneland be able to switch to it (you may need to refresh the page before it appears in the list). IPython will remember which kernel to use for that notebook from then on.
Note: For this to work, your virtualenv must be in the standard virtualenv directory. That is ~/.virtualenvs
