[julia-users] ijulia with multiple versions
I have multiple versions of julia installed on my machine. Is there an easy way to specify which version of julia I want to use when running ijulia? Simon
Re: [julia-users] ijulia with multiple versions
IIRC, the julia path is hard-coded in the profile spec under ~/.ipython So, you could copy/rename the profile folder and change the path, for each julia version (and then probably create a launcher script to start 'ipython --notebook --profile=PROFILENAME' as needed) On Dec 8, 2014 5:58 AM, "Simon Byrne" wrote: > I have multiple versions of julia installed on my machine.

Fantastic, thanks! For the record, in case anyone else is interested: cd ~/.ipython cp -R profile_julia profile_julia4 Then open ~/.ipython/profile_julia4/ipython_config.py and find the line starting with "c.KernelManager.kernel_cmd = ", to point to the relevant julia executable and ijulia package path. Then ipython notebook --profile=julia4 to start.

Does Jupyter not have this sort of functionality? Christoph On Monday, 8 December 2014 12:20:08 UTC, Simon Byrne wrote: > > Fantastic, thanks!

I think they're working on it, but it's not there yet.

Re: [julia-users] ijulia with multiple versions
In fact there is a way to do this.
Just go to the REPL with the Julia version you want to switch to and run
Pkg.build("IJulia"). This replaces the julia profile files in ~/.ipython to
use the right Julia executable.
Re: [julia-users] ijulia with multiple versions
I meant from Jupyter UI. I think that switching kernels in notebooks is in
progress.

Right, but this is kind of slow and would be annoying to do for routine use
I think.
Another option might be to change the hard-coded path to look at an
environment variable instead (or a global set from a wrapper script, etc.)
