No "Enter/Exit Live Reveal Slideshow" button on jupyter notebook.

[andrelucchini]

Hi, I just downloaded Rise from the conda, as you showed here on github, but when I'm using jupyter, the button to enter the presentation doesn't appear. Usually I use the sagemath kernel, but it doesn't even appear with the python kernel. Do I have to do any more installation or do I need a specific command to connect it to the sagemath jupyter notebook?

Thank you for your attention, as well as for this repository.

hi

in theory, the notebook extension does not depend on the kernel, I have successfully used rise with a number of kernels so far

in theory again, simply installing rise through pip or conda should install and enable the notebook extension (although I only use pip to do that myself)

I have no exposure to the sagemath kernel at all, so I suggest we start with focusing on getting your installation to work with a python kernel for starters

can you please provide

• your OS version and your Python installation strategy (which Python distrib and how you install additions)
• the make, and version of your browser
• a snapshot of your browser console when loading the notebook where the button fails to appear; expect it to be a little verbose, we want to focus on odd-looking errors

that last piece of info is probably the most useful

[andrelucchini]

First of all, thanks for the help and willingness, I appreciate that.

• My OS: Linux Mint 20.1 Cinnamon, Cinnamon version: 4.8.6
• I have python in the following versions: 2.7.18, 3.8.5 e 3.9.4(conda). I installed them from the default repository of my OS, that is, I did not configure any new PPA.
• My browser info: Google Chrome - Version 90.0.4430.212 (Official version) 64 bits
• I just installed the new version of sagemath and my jupyter notebook was installed by anaconda. It is up to date, but still has problems with the extension. I will send the snapshot of the browser console.

EDIT: My ipywidgets version is 6.0.0

Hi your javascript console output has several error messages of concern :

• both 404 not found that refer to the /nbextensions/ path
• the Script Error about jsmol/extension

this suggests that one or several other nbextensions are ill-installed, and it seems the likely root cause of your problem

I'm not exactly sure how to address that the most effectively though, it might make sense to disable some or all other exensions maybe on Jupyter's discourse people can provide guidance on how to do this best ?

https://discourse.jupyter.org/

sorry that I can't be more helpful

[andrelucchini]

There's no reason to apologize, it helped me a lot. Thanks again for your attention and willingness to help, I will follow your advice and look on Jupyter's discourse.

Thank you, again.

[damianavila]

it might make sense to disable some or all other exensions

Yep, that would help to diagnose... then it seems trying to find out what the other extension is failing would be the second step. I agree with @parmentelat is a good place to ask. It would be also a good idea to contact the creators of the other extensions to check with them what could be happening.

[ddddavidee]

Did you solve? I have the same issue on Ubuntu. fresh venv with python 3.9, pip install RISE and no button, nor Alt-R working.

[parmentelat]

hey to my knowledge there has been no recent development on this issue

like for @andrelucchini I would suggest that you

• send over a screenshot of you javascript console so that we can have a better grip on what can be going on in your case
• try to disable other extensions as far as possible; in the sceeenshot above for example, there clearly was an issue with loading the jsmol extension - whatever that is - and this kind of glitch can have contaminating effects on other extensions like rise

hope this helps

[ddddavidee]

I created an clean virtual env and installed only jupyter and RISE. (I did not install other extensions)

hi

I am not 100% positive that this way of doing things implies no other extension is active indeed jupyter has its own configuration cascading mechanism that does not always play well with virtualized envs honestly I myself use miniconda and so I can't say for sure about venv BUT one way to get a better understanding of what's going on is to run

jupyter --paths

so as to see which folders are actually involved in the computing of eventual settings and of course

jupyter nbextension list

if I'm right this could show other extensions that you unaware inherit from the host environment

could we first check that before we search for other possible causes ?

PS not that it could be a killer weapon here, but for just in case let me mention the possibility to define

JUPYTER_PREFER_ENV_PATH=1

as explained here https://discourse.jupyter.org/t/jupyter-paths-priority-order/7771

[ankusharya]

Hi, I was also facing the same issue. Here is how I solved it. My installation settings.

1. Using WSL(Ubuntu 20.04 LTS) on windows with python and jupyter-notebook installed
2. Not using VirtualEnv for python
3. No extensions installed.(Rise was the first extension I really needed so I though of giving it a try)
4. Rise version 5.7.1

Steps which I did to solve issue at my end.

1. Install widgetsnbextension pip install widgetsnbextension
2. Enable widgetsnbextension jupyter nbextension enable --py widgetsnbextension
3. Remove rise if installed and install it again pip uninstall rise pip install rise
4. Enable rise as extension jupyter nbextension enable --py rise if you have virtual env enabled i think we need to append --sys-prefix to each enable command

Now if you run jupyter-nbextension list you can see rise and one of the extension

Its working fine after I followed these steps.

[DrDids]

Hi, I also have Rise version 5.7.1

and

config dir: /Users/lgzdl/.jupyter/nbconfig

notebook section
  jupyter-js-widgets/extension  enabled 
  - Validating: OK
  rise/main  enabled 
  - Validating: OK

config dir: /usr/local/anaconda3/etc/jupyter/nbconfig notebook section rise/main enabled - Validating: OK voila/extension enabled - Validating: OK jupyter-js-widgets/extension enabled - Validating: OK

but nope no Alt-R. I can export using Reveal.js but no live rendering. I can do a live rendering with voilà ... Could there be a conflict between voilà and RISE?

Thanks

[parmentelat]

hi

how did you install rise ? I personally don't use conda; if you've installed with conda can you try installing with pip instead to see if that's better ? also, in a completely other direction, can you post a screenshot of you web console when the issue occurs and alt-r won't work ? I take you don't see the rise button either ?

[DrDids]

Hi, I did both (at first using pip) and in the current setting with conda. I have a little greyed button next to R on the top left .. could that be the missing rise button? Thanks

[parmentelat]

Ah! but this is jupyterlab, and rise unfortunately supports only jupyter classic !
