Is IJulia meant to be working with Julia v1.0 yet?

Lemniscate · August 11, 2018, 5:45pm

I’ve been trying to get IJulia/Jupyter notebook to work on my (Windows 10 64 bit) computer. I installed Julia v1.0 (before this I was using Julia v0.6 which worked fine) and then installed IJulia, which gave the following message:

(v1.0) pkg> add IJulia

When I opened Jupyter lab I saw the Julia 1.0.0 kernel as an option and was able to start a Julia notebook. However, when I tried to execute my first cell the computation never finished running, and my Jupyter console showed the following:

slowbrain · August 12, 2018, 3:35pm

indeed, fails on Windows 7 for me

ceysa75 · August 18, 2018, 7:11am

Wanted to make my first steps with Jupyter. However, same issue here… Win10 64 Bit, Julia 1.0. Hints as given above are too complicated, at least for me. Thought, it’s just a straightforward thing with Julia&Jupyter…

bobmccrory · August 23, 2018, 6:15pm

IJulia hangs randomly on all three machines I’ve tried it on. All are running Window 10 (64 bit). Sometimes IJulia runs a notebook to completion, but most often it fails part way through. Since I’m just learning Julia, these notebooks are not complicated. I’ve tried the “dev IJulia” trick in the package manager suggested in issue #693. Initially that seemed to help, but not so much today.

Thanks to all who are working on this.

BLI · August 23, 2018, 9:23pm

I’ve tested IJulia on both Julia 0.7 and Julia 1.0 on Windows 10 (64bit) machines.

If I start IJulia, a simple thing like 1+1 doesn’t work, and the notebook hangs.
If I interrupt the kernel, and switch to Python 3, there are a few messages flashing in the notebook heading: 1) No kernel in orange text box, 2) Kernel starting, please wait... in white textbox, and finally, 3) Kernel ready in blue textbox – before that message disappears.
With Python 3 kernel, operations like 1+1 respond immediately.
Switching back to Julia 0.7.0 kernel, the following messages flash in the notebook heading: a) No kernel in orange text box, b) Kernel starting, please wait..., and finally c) Connected in blue textbox.
Again, IJulia doesn’t work.

I don’t know if the difference in message is important… Kernel ready when starting Python 3, and the system works… Connected when starting Julia 0.7.0 when the system doesn’t work.

Another observation is that when I start the Python 3 kernel, the message No kernel in orange is shown for some time (5 seconds or so?), while when I start the Julia 0.7.0 kernel, the message No kernel in orange is shown for only a very short time (0.1 second or so?).

I got IJulia to work with Julia v1.0 on Windows 10 by entering the following in the Julia REPL

(v1.0) pkg> add IJulia
ENV["IJULIA_DEBUG"] = true
(v1.0) pkg> dev Ijulia

John_Gibson · August 23, 2018, 10:11pm

IJulia 1.9.3 works with Julia 1.0.0 on Linux.

Try running using Pkg; Pkg.update() to get the latest IJulia. That fixed an UndefVarError: srand not defined for me.

PetrKryslUCSD · August 24, 2018, 1:19am

I don’t know man, it still hangs for me. (With Julia 0.7.0, Windows 10)

jandehaan · August 24, 2018, 1:43am

IJulia didn’t work with my installation of Julia 0.7.0 either. I therefore I uninstalled Julia 0.7.0 and deleted the associated directories. I then reinstalled Julia 0.7.0 from scratch.

I opened Julia REPL and ran the following (which is slightly different from what I wrote above).

(v1.0) pkg> add IJulia
julia> ENV["IJULIA_DEBUG"] = true
(v1.0) pkg> dev IJulia
(v1.0) pkg> build IJulia

And IJulia now works with Julia 0.7.0 too on my computer (Windows 10)

PetrKryslUCSD · August 24, 2018, 2:42am

No luck for me. I couldn’t even get the damn thing to build:

julia> ENV["IJULIA_DEBUG"] = true
true

Sorry to hear that. I don’t know what to suggest next.
Below is a printout of my REPL session after I installed Julia 0.7.0 from scratch. Maybe there is something in there that may help.

It is a Windows only problem, see https://github.com/JuliaLang/IJulia.jl/issues/693.

stevengj · September 4, 2018, 12:23pm

Should hopefully be working now once you do a Pkg.update.

Ajaychat3 · September 18, 2018, 11:10am

I took the following steps to install IJulia and it works both on Julia 0.7 and 1.0 version on Win10. I am using normal installation of Python (not Conda).

ENV[“PYTHON”] = specify path to ptyhon.exe
ENV[“JUPYTER”] = specify path to jupyter.exe
using Pkg;Pkg.add(“IJulia”);Pkg.build(“IJulia”)
using IJulia

Hope it helps.

stevengj · September 18, 2018, 12:22pm

On Windows it is also possible to use IJulia via Conda. However, there is currently a bug in the Anaconda installer for Python 3 that is affecting us, and the workaround is that you need to tell Conda.jl to install using Python 2:

&& if errorlevel 1 exit 1 ``` However, `%PREFIX%` is not defined on my system. I manually added PREFIX as a system enviornment variable that points to the folder of the Python executable from miniconda (in my case `C:\Users\K19\.julia\packages\Conda\m7vem\deps\usr\pkgs\python-3.7.0-hea74fb7_0`) and ran refreshenv. I compiled IJulia again using `Pkg.build("IJulia")` and it failed again. I ran the aforementioned script again, and it tells me that "No module named ipykernel". I don't know if IJulia is at fault but since I encountered this problem while installing IJulia I'll submit my issue here. Feel free to point me to other places.

If someone who uses Windows could take the time to file a proper bug report (e.g. by downloading the minconda installer and running it manually to reproduce in a clean example) with Anaconda that would be much appreciated.

IJulia does not work for me in Windows 10 or Kubuntu 18.04. Juliapro 1.0.2. Jupyter notebook can be started and notebook opened but it fails to connect to kernel, and after that shows “dead kernel”. Message

A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.

Here is what I type in Kubuntu:
is also shown.

On Windows there warnings don’t appear but nevertheless the same error appears with the notebook:

Please don’t resurrect old threads — IJulia has been working on Julia 1.0 for ages, for most people — to raise unrelated installation issues. Or in your case, two unrelated issues! Not all installation failures have the same cause, and you should generally try to file issues at the source of the problem.

In your first case, the error on KUbuntu seems unrelated to IJulia per se (you are seeing an error loading Compat, which also definitely works) and may be a problem with your JuliaPro installation. Try reinstalling, or downloading the standard Julia rather than JuliaPro, or filing a JuliaPro issue.

The warning about “creating file symlinks requires Administrator privileges” (which arises on networked filesystems on Windows, I think), seems to have a come up a bunch packages last fall (e.g. https://github.com/JuliaInterop/CxxWrap.jl/issues/124); it may be fixed by a package update if the problem is BinaryProvider as the issue I linked suggests. In any case, it is also not an IJulia issue per se.

Ok. I got it working with the standard Julia 1.1.0 on Kubuntu 18.04.
