Use Julia from Jupyter notebook

IJulia allows running Julia from within the web browser-based Jupyter IDE. In general (for all operating systems) it’s recommended to install and update Julia via the downloads from Julia website.

Install Jupyter: locate Jupyter binary location

  • Windows: where jupyter
  • Linux, macOS: which jupyter

If Jupyter is not installed, just do

conda install jupyter

Install IJulia: start Julia with this environment variable (only necessary once)

  • Linux / macOS:

    JUPYTER=$(which jupyter) julia
  • Windows:

    $Env:JUPYTER=$(where.exe jupyter)

Finally, type at Julia prompt:

using Pkg


This installs numerous packages via conda automatically.

Existing .jl files are NOT runnable from IJulia. Start the Notebook by EITHER:

  • Terminal/Command Prompt: jupyter lab
  • Julia: using IJulia; notebook()

Create an interactive Julia .ipynb Julia notebook by clicking New → Julia.
