How to install and start the 0.4-pre Julia kernel with IPython notebook?

Question

I installed the 0.4-pre Julia kernel on a mac, which goes into

/Applications/Julia-0.4.0-pre-349a4e1977.app/Contents/Resources/julia/bin/julia

and set the symbolic link to this kernel

ln -s /Applications/Julia-0.4.0-pre-349a4e1977.app/Contents/Resources/julia/bin/julia /usr/local/bin/julia

but in my IPython notebook, aka Jupiter, the 0.3.10 starts up when

ipython notebook --profile=julia

How to include the 0.4-pre kernel option in the IPython notebook?

Answer 1

Thanks for the answers. Using the info from @ARM and @David P. Sanders, what eventually worked for me on a mac was:

1. Run the downloaded julia 0.4-pre in a Terminal: exec '/Applications/Julia-0.4.0-pre-349a4e1977.app/Contents/Resources/julia/bin/julia', which gives me a Julia prompt.
2. At this Julia prompt run Pkg.add("IJulia"), which creates a ~/.julia/v0.4 directory and installs IJulia and a few other packages in that directory.
3. quit() from this julia prompt.
4. Navigate to the directory in the Terminal where your myNotebook.ipynb's are or where you want to create them and run ipython notebook at the Terminal prompt, which should open a webpage on localhost:8888 with that directory's files listed. Click on the file you want edit.

If you have IPython/Jupyter version 3 or above, then you should start it with

ipython notebook

without the

--profile julia

Answer 3

You need to Pkg.add("IPython") and Pkg.build("IPython") in 0.4 to add the 0.4 kernel spec to Jupyter. This is similar to the instructions for when you update Julia here.
