Rise: Slideshow invisible

[ThomasA]

I have just installed the latest RISE in a freshly installed Anaconda Python environment. Installation seems to work well, the slideshow button shows up in notebooks, and I can start the slideshow, but: the slideshow is invisible. Content is visible during transitions, but as soon as the transition has stopped, the slide turns blank. Hovering over the page with the mouse reveals that the slide text still seems to be there, but it is invisible.

Steps to reproduce:

• Install fresh Anaconda environment and RISE
  bash conda create -n test-rise anaconda python=3.5 source activate test-rise conda install -c damianavila82 rise
• Open this notebook: https://gist.github.com/ThomasA/69290e5a025dbc630c909b5af2ca1eff
  Very simlpe notebook with a Markdown slide and a code slide
• Start the slideshow. The slides show the above described behaviour on my computer.

I should note that I have attempted to remove left-overs of previous RISE installs by deleting '\~/.local/share/jupyter/nbextensions/livereveal/' and '\~/.ipython/nbextensions/livereveal'. I do not know if there could be any other left-overs causing trouble somewhere?

Sorry for the delay.

What is the output of jupyter nbextension list?

Similar issue today.
A recent install of Anaconda3, I installed RISE using
conda install -c damianavila82 rise

I can select "Slideshow" mode enabling the cell toolbar but I don't see the Enter/Exit Live Reveal Slideshow" button in the notebook toolbar (I only see nbpresent buttons).

[mjbright]

OK, problem solved in my case.

I tried
jupyter-nbextension install rise --py --sys-prefix
jupyter-nbextension enable rise --py --sys-prefix

reloaded my notebook and the RISE button appeared.
and now jupyter nbextension list gives

@mjbright did you have any failure message when you install it? The jupyter-nbextension commands should not be necessary... the conda package should take care of that...

I've exactly the same problem, the slideshow starts but the text shows up only during the transition, then it disappear immediately letting a white page.

@ghislainp I would suspect of some kind of interaction with other extensions. Can you try backing up your config at /home/me/.jupyter and install RISE in a new clean environment to see if there is some interaction? Thanks.

[ghislainp]

I've tried to remove all the .jupyter and /etc, and I've tried to install a new fresh environment... still the same problem.
BUT
I tried with chromium and it works. The problem is only in firefox.

[damianavila]

I tried with chromium and it works. The problem is only in firefox.

OK... nice to know... which Firefox version is failing for you?

[ghislainp]

53.0.3 under linux

[mhardcastle]

I also have this problem on firefox (52.3.0, debian stretch); fine on chromium. Old versions of firefox work fine.

Thanks for the info!

slide show button is not displaying in the toolbar even after successful installation of RISE in my jupyter environment, please let me know any issue here!

[damianavila]

@sumendar, we need more information about your setup. Some questions:

• notebook version?
• browser version?
• can you try hard-reloading your browser (some info here: https://www.getfilecloud.com/blog/2015/03/tech-tip-how-to-do-hard-refresh-in-browsers/#.Wnmm25M-dhE, to get rid of the cache)?
• can you try installing in a new environment without other extensions to get rid of possible interferences?

[damianavila]

Additionally, do you have any output in the js console? If that is the case, please also report it.

[sumendar]

I installed recent anaconda Python 3.6 version,
browser is Google chrome Version 64.0.3282.167 (Official Build) (64-bit)
and i installed RISE into two different machines, the same problem facing (slideshow button is not appearing on jupyter notebooks) , also suggest do we have any other way to enable slideshow (shortcut or menu items....etc)

[damianavila]

Can you try upgrading the notebook package, or even better, create a new environment and install rise on it. Btw, if you could report what I asked before, it would help. Thanks.

[reberac]

Hello,
Same issue for me, the slideshow button was not appearing on jupyter notebook. However, after an upgrade of the notebook package as suggested by Damia, it works, thanks !

[sumendar]

yes it works after up-gradation! but my nbextention icons on toolbar are changed to more descriptive than small icons as shown below

[damianavila]

@sumendar, what notebook version and rise version do you have? I would bet you still need to upgrade to the latest notebook version...

[martindurant]

Confirmed, the following updates made RISE work for me (py35, osx)

    jupyter_client: 4.3.0-py35_0 --> 5.2.2-py35_0
    jupyter_core:   4.3.0-py35_0 --> 4.4.0-py35h4ad9194_0
    notebook:       5.0.0-py35_0 --> 5.4.0-py35_0
    terminado:      0.6-py35_0   --> 0.8.1-py35_1

with RISE

rise                      5.2.0                    py35_0    damianavila82
