Installing Julia in Windows and Running in Jupyter Notebook

Installation of Julia

  • First download the installer from official site then run the installer.
  • Set the environvent path variable.
  • Test it by opening the Julia Command Line or REPL (Read Eval Print Loop).
println("hello world")


Adding Julia into Jupyter

  • First add package IJulia by typing use Pkg and then enter.
  • Then Pkg.add("IJulia").
  • Wait for the completion.


Test it

  • Hit jupyter notebook from anaconda prompt or terminal.
  • Selct Julia from dropdown.

  • Create a new notebook and run a code.

Plot in Julia

Lets try to plot a Lorenz Attractor visualization in Julia. For code reference check here.

But we need to install package Plots. So lets do it from Julia Command Line by:

using Pkg

Please have patience, it will take some time.

Once done something like below will be seen.

using Plots
# define the Lorenz attractor
Base.@kwdef mutable struct Lorenz
    dt::Float64 = 0.02
    σ::Float64 = 10
    ρ::Float64 = 28
    β::Float64 = 8/3
    x::Float64 = 1
    y::Float64 = 1
    z::Float64 = 1

function step!(l::Lorenz)
    dx = l.σ * (l.y - l.x)
    dy = l.x * (l.ρ - l.z) - l.y
    dz = l.x * l.y - l.β * l.z
    l.x += l.dt * dx
    l.y += l.dt * dy
    l.z += l.dt * dz

attractor = Lorenz()

# initialize a 3D plot with 1 empty series
plt = plot3d(
    xlim = (-30, 30),
    ylim = (-30, 30),
    zlim = (0, 60),
    title = "Lorenz Attractor",
    marker = 2,

# build an animated gif by pushing new points to the plot, saving every 10th frame
@gif for i=1:1500
    push!(plt, attractor.x, attractor.y, attractor.z)
end every 10

Once done, a tmp.gif file will be stored on the working directory.

Reading CSV

Reading Local CSV

  • Add packages CSV and DataFrames.

  • Now using it.

using CSV, DataFrames"country_info_lat.csv",DataFrame, header=1, delim=",")
