Julia kernel for Jupyter

Build Status Build status


IJulia is a Julia-language backend combined with the Jupyter interactive environment (also used by IPython). This combination allows you to interact with the Julia language using Jupyter/IPython's powerful graphical notebook, which combines code, formatted text, math, and multimedia in a single document. IJulia is a Jupyter language kernel and works with a variety of notebook user interfaces. In addition to the classic Jupyter Notebook, IJulia also works with JupyterLab, a Jupyter-based integrated development environment for notebooks and code. The nteract notebook desktop supports IJulia with detailed instructions for its installation with nteract.

(IJulia notebooks can also be re-used in other Julia code via the NBInclude package.)

Quick start

Install IJulia from the Julia REPL by pressing ] to enter pkg mode and entering:

add IJulia

If you already have Python/Jupyter installed on your machine, this process will also install a kernel specification that tells Jupyter how to launch Julia. You can then launch the notebook server the usual way by running jupyter notebook in the terminal.

Alternatively, you can have IJulia create and manage its own Python/Jupyter installation. To do this, type the following in Julia, at the julia> prompt:

using IJulia

to launch the IJulia notebook in your browser. The first time you run notebook(), it will prompt you for whether it should install Jupyter. Hit enter to have it use the Conda.jl package to install a minimal Python+Jupyter distribution (via Miniconda) that is private to Julia (not in your PATH).

For more advanced installation options, such as specifying a specific Jupyter installation to use, see the documentation.
