IJulia Installation on Windows #363

ericjang · 2015-09-27T13:13:18Z

I am using Windows 10 and Anaconda with julia-0.5.0. I previously had IJulia installed and working, but then somehow calling Pkg.update() broke my installation.

Here is the error message:

===================================================[ ERROR: IJulia ]====================================================

The text was updated successfully, but these errors were encountered:

I have proposed a fix in #364 could you check if it works?

ericjang · 2015-09-27T16:29:14Z

Simply patching those 2 lines didn't seem to work for me:

I ran Windows Powershell with administrator and did pip install --upgrade jupyter (I'm using Anaconda), then ran jupyter kernelspec in Windows powershell but got

"jupyter: kernelspec is not a Jupyter command"

dhoegh · 2015-09-27T16:36:06Z

Ok. Have you tried the orginal build script after pip install --upgrade jupyter? Do excuting jupyter-kernelspec --version work now?

ericjang · 2015-09-27T16:39:01Z

Yep, it yields the error above (kernelspec is not a Jupyter command).
I also get this error when I run jupyter kernelspec --version in Powershell.

Do I need to be using the dev branch of Jupyter notebook for kernelspec to show up?

dhoegh · 2015-09-27T16:41:24Z

Sorry the comment split the line unfortunate it is jupyter-kernelspec --version where jupyter and kernerlspec joined by -.

ericjang · 2015-09-27T16:48:04Z

Unfortunately, that doesn't work either :/

PS C:\Users\eric> jupyter-kernelspec --version

dhoegh · 2015-09-27T16:50:04Z

Do the command work in cmd instead of powershell?

ericjang · 2015-09-27T16:53:48Z

tried that, doesn't work either.

jupyter --version returns 4.0.6

Strangely enough, running jupyter -h lists the following subcommands:

Available subcommands: console kernelspec migrate nbconvert nbextension
notebook qtconsole trust

dhoegh · 2015-09-27T17:12:30Z

Hmm. I am indeed confused now. I think the only resolution to this is to wait for jupyter/jupyter_core#62 or downgrade to IPython3. Alternative you could let IJulia use the Conda package which can be done by:

julia> ENV["JUPYTER"]=""
julia> Pkg.build("IJulia")

stevengj · 2015-09-27T23:31:27Z

If jupyter-kernelspec is not in the PATH either, that sounds like it is a different problem from jupyter/jupyter_core#62 ... sounds like a problem with your Anaconda installation?

dhoegh · 2015-09-28T05:23:49Z

It sounds like what minrk describes here, jupyter/notebook#448 (comment) where jupyter/jupyter_core#62 is the PR for fixing the issue.

n-s-k · 2015-09-30T14:27:09Z

I had the very same issue, using jupyter --version 4.0.6:

jupyter: 'kernelspec' is not a Jupyter command

If I try to Pkg.build('IJulia'):

could not spawn jupyter-kernelspec install --replace --user julia-0.5: no such file or directory (ENOENT).

My understanding is that although Anaconda\Scripts is in the PATH and contains jupyter-kernelspec, this latter is not a windows executable.

As a temporary workaround, I replaced line 101 of build.jl with:

run(`python C:\\Anaconda\\Scripts\\$jupyter-kernelspec install --replace --user $juliakspec`)

and ran Pkg.build('IJulia') again.

I still don't get it and I'm certain there is a cleaner solution.

stevengj · 2015-09-30T15:21:25Z

@n-s-k, does jupyter-kernelspec --version work in run?

n-s-k · 2015-09-30T15:37:44Z

julia> run(`jupyter --version`)
4.0.6
julia> run(`jupyter-console --version`)

julia> run(`jupyter-kernelspec --version`)

stevengj · 2015-09-30T15:45:57Z

What is jupyter-kernelspec? A batch file? (If so, why doesn't it end with .bat?)

Oh, from above I guess it is a Python file? (But doesn't end with .py?)

stevengj · 2015-09-30T15:48:06Z

On my Mac, jupyter-kernelspec is

#!/Users/stevenj/anaconda/bin/python
from jupyter_client.kernelspecapp import KernelSpecApp

def main():
    KernelSpecApp.launch_instance()

if __name__ == '__main__':
    main()

but I guess Windows doesn't know how to spawn this.

n-s-k · 2015-09-30T15:49:38Z

On Windows, jupyter-kernelspec is:

#!C:\Anaconda\python.exe
from jupyter_client.kernelspecapp import KernelSpecApp

def main():
    KernelSpecApp.launch_instance()

if __name__ == '__main__':
    main()

yep... a python script and Windows is clueless.

stevengj · 2015-09-30T15:50:59Z

Okay, this should be a straightforward fix. We just need to find the correct path of jupyter-kernelspec and run it with Python.

stevengj · 2015-09-30T18:23:24Z

Okay, it should be fixed now. Please do Pkg.checkout("IJulia"); Pkg.build("IJulia") and confirm that it works. Once you confirm, I will tag a new version.

n-s-k · 2015-09-30T18:43:58Z

Confirmed.

ericjang · 2015-09-30T19:44:59Z

This works for me too. Thanks!

Great, tagged as IJulia 1.1.2.

I'm hitting this with the latest tag.

C:\Users\Tony\.julia\v0.4\Conda\deps\usr\Scripts has a jupyter-kernelspec.exe and a jupyter-kernelspec-script.py, but no plain jupyter-kernelspec without an extension. It looks like this may differ depending on anaconda or jupyter version?

stevengj · 2015-10-05T20:14:21Z

Hmm, do we need a similar fix on windows to get notebook() working?

#270 by doing explicit kill

minrk · 2015-10-10T11:46:48Z

I believe several of these issues (esp #368) were caused by improper packaging of entrypoints in the Jupyter projects on Windows. Most of the entrypoints were fixed relatively promptly during the summer, but jupyter-client never got a release with the fix until 4.1, this week. I thought we had done that a while ago, but we hadn't. Hopefully this will be better behaved with the 4.1 update to jupyter-client.

stevengj · 2015-10-10T12:08:12Z

Thanks, @minrk. We will keep the workarounds in for quite some time, to support older installations, but it is great to hear that this has been fixed.

This proposed change amends and extends the previously included (so-called) hacks for Windows that were added for issue JuliaLang#363 (that are waiting on issue JuliaLang#448 for the jupyter project). These changes allow for IJulia to work a version of Python that has been downloaded from python.org, where jupyter was pip installed with a version recent enough to include jupyter-kernelspec.exe and jupyter-notebook.exe, and where the end user has set the JUPYTER environment variable either at the system level or in ENV within their Julia session prior to building IJulia via Pkg.build. If the issues that led to the discussion in JuliaLang#363 and jupyter issue JuliaLang#448 have been addressed, then the changes in this commit and PR can likely be ignored.

On Windows 7, 64-bit.
Installed Julia v0.4.5 -> Installed Anaconda (Python 3, 64 bit)
ran Pkg.add("IJulia") and it failed.
I installed Julia v0.5 (unstable version) and it worked.

Here is the error:

@bsouthwood, that should be reported at Conda.jl

bsouthwood · 2016-04-26T22:32:53Z

Apologiea, i'm a noob.. I checked line 35 of the build.ml file and it contained a jupytyr variable so i thought it was related to this threas.

hayd · 2016-05-21T18:21:46Z

It looks like IJulia.jl is using the globally installed jupyter/ipython (rather than one locally installed from Conda.jl). This means that if you have ipython installed but not jupyter (specifically jupyter_client, though with just that notebook() will just immediately exit) you'll get the error noted above.

stevengj · 2016-05-23T14:19:48Z

@bsouthwood, to simplify installation, do ENV["JUPYTER"]=""; Pkg.build("IJulia") ... this will use the Conda Jupyter and will auto-install everything for you.

bsouthwood · 2016-05-23T14:40:17Z
