[sage-support] gwsl2

[Henri Girard]

For those who want a running sagemath linux on windows 10/11 or amber20 
or any app not working on windows use gwls2 very easy to install 
(actually ubuntu 20.04 for me but I tried to upgrade to 22.04 (+1) and 
it works fine so I even have sage 9.4, I can't get any more for the 
moment on it !)


The detail help on microsoft help is suffisiant to install wsl2 and then 
get the gwsl2 on microsoft store with one click installation.


Sorry but I didn't know where posting this info for sage users

Best

Henri

I have run the Recommended_9_5.pkg file.

 I am not sure I follow here. How do you install Sage? 

 The basic thing that should work is starting Sage from terminal, as 

 sage -n 

 The macOS GUI we used to have is quite broken, and was removed, the 
 one we currently recommend is

Re: [sage-support] Re: Interact broken. SageMath 9.5 on Apple Mac OSX 12.1 . SageMath-9.5_x86_64

[Marc Culler]

At some level the problem is that the Tornado web application used by 
Jupyter is returning a 404 when the client tries
to load:

http://localhost:/nbextensions/widgets/notebook/js/extension.js?v=20220201102631

I have no clue how the Tornado web application tries to translate that URL 
into a path to a static file named extension.js.
But that file does exist.  The difference between 9.4 and 9.5 with respect 
to that file is that it moved from local/share to
venv/share.  So I would guess that there is some part of how Jupyter 
configures its Tornado web application which
was not correctly adjusted to compensate for that change.

Re: [sage-support] Re: Interact broken. SageMath 9.5 on Apple Mac OSX 12.1 . SageMath-9.5_x86_64

[Marc Culler]

So is Sage following those instructions during its build process?  The docs 
do not say what those jupyter commands actually do.  They have separate 
instructions for enabling the widgets when using a virtualenv.  Of course 
Sage's venv is not a true virtualenv as created by venv, so it is hard to 
know whether the virtualenv instruction apply for Sage or not.  But given 
that the widgets worked before Sage switched to its virtualenv-like venv I 
would guess that they do apply.

It is unclear to me whether this is an issue with the packaging of the 
SageMath app for macOS or whether it is an issue with Sage's build process, 
which I follow when building Sage for the app.  It would be helpful to know 
the meaning of the sentence "Most of the time, installing ipywidgets 
automatically configures Jupyter Notebook to use widgets."
Specifically, what does it mean to "configure Jupyter Notebook to use 
widgets".

It is actually a true venv, unless no system python can be used and Sage 
builds its own copy of python3.

Well, OK.  Maybe so.

But I've never seen a venv that resulted in a path like
sage/local/var/lib/sage/venv-python3.9.9/var/lib/sage/.

No.  I was referring to
https://ipywidgets.readthedocs.io/en/latest/user_install.html which was
Samuel's [more details here] link.

Incidentally, following those instructions did result in a log message
indicating that the widgets had been enabled in Jupyter.  But there was no
change in the behavior.  Attempting to load extension.js still produced a
404.
