Document setting up and running Julia + Julia Kernel

[stegua]

Is it possible to have Julia notebook in addition to Python3 notebook?

Otherwise: thanks a lot! I used your LittlestJupytherhub for an high school stage yesterday, and it worked very well. The only issue was that I did not set a memory limit per user, and a couple of users took all the memory, and I had to restart the server.

Thanks.

hmmm, good question...since you can conda install things, could you try installing julia with conda and see if that works? Not sure how you'd set this up without conda and pip though.

using conda, the following should work for a single user environment:

conda create -n julia_env -c conda-forge julia
source activate julia_env
julia # enter julia console

afterwards, inside the jula console to add the kernel:

ENV["JUPYTER"]="/opt/tljh/user/bin/jupyter"
using Pkg
Pkg.add("IJulia")

To make the environment available to all users, you will need some sudo commands when installing the environment and registering the kernel. Unfortunately the following didn't work for me (altered from installing R kernel). Maybe you can figure it out from here:

sudo -E conda create -n julia_env -c conda-forge julia
source activate julia_env
sudo -E julia # enter julia console and see above

I think having a section in the docs dedicated to enabling Julia and R notebooks would be very useful!

I have a JupyterHub up and running and performed the above steps for all users. The install seems to work but when I try to verify the Julia Kernel with println("Hello Julia.") the kernel seems to never produce a response in the Jupyter Notebook. Any ideas on how to trouble shoot this?
Thanks

@josephc31415 Looking at logs for the particular user (http://tljh.jupyter.org/en/latest/troubleshooting/logs.html#user-server-logs) might be useful!

Is there any update on the documentation for enabling IJulia on TLJH? I have been able to install and run Julia from the terminal for all users in my TLJH server, but could not find a way to enable Julia notebooks. I don't have much experience with Julia, so would greatly appreciate help in figuring this out. Thank you!

I agree that it would be great if a current Julia kernel was a standard feature in TLJH.
Anyone recently have any success with an install that successfully integrated with both Jupyter Notebooks and Jupyter Lab?
