Before you start Jupyter Notebook, you need to have Julia create a local kernel.
First, activate the notebook environment from the command line:
anaconda3-activate
conda activate notebook
Now, start Julia on the command line, and type these commands:
using Pkg
Pkg.add("IJulia")
import IJulia
Finish with typing Ctrl-D.
Now you can start Jupyter Notebook:
jupyter-notebook
... and when you click New in the menu, there should be an option to select Julia.
using Pkg
Pkg.add("PyPlot")
import PyPlot
x = range(0, stop=2pi, length=200)
y = sin.(x)
PyPlot.plot(x, y);
