Kernel Installation

IPython can be installed (different python versions, virtualenv or conda environments) as a kernel by following these steps:

• make sure that the desired python installation is active (e.g. activate the environment) and ipython is installed
• run once ipython kernelspec install-self --user (or ipython2 ... or ipython3 ... if you want to install specific python versions)

The last command installs a :ref:`kernel spec <jupyterclient:kernelspecs>` file for the current python installation. Kernel spec files are JSON files, which can be viewed and changed with a normal text editor.
