No button in new kernel tab

[NGillet]

Hello, I just try to install Rise using conda but the button "Enter/Exit Live Reveal Slideshow" does not appear. I tried on 3 machine, 2 linux and 1 mac, with fresh install anaconda3, but I did not manage to make it work :(

let focus on the mac: High Sierra : version 10.13.2 conda 4.4.10 jupyter --version 4.3.0 Google Chrome Version 64.0.3282.140 (Build officiel) (64 bits) (I tried the hard reload stuff... no success)

conda list rise rise 5.2.0 py36_0 damianavila82

jupyter nbextension list Known nbextensions: config dir: /Users/gillet/.jupyter/nbconfig notebook section rise/main enabled

• Validating: OK jupyter-js-widgets/extension enabled

And the JS console in the kernel tab : Loading extension: rise/main require.js?v=6da8be361b9ee26c5e721e76c6d4afce:900 TypeError: Cannot read property 'help' of undefined at toolbar.js:101 at MainToolBar.ToolBar.add_buttons_group (toolbar.js:115) at Function.setup [as load_ipython_extension] (main.js?v=20180213124755:953) at utils.js:39 at Object.execCb (require.js?v=6da8be361b9ee26c5e721e76c6d4afce:1690) at Module.check (require.js?v=6da8be361b9ee26c5e721e76c6d4afce:865) at Module.

An error appear here... But I have no idea of how to solve it...

Hi!

Some questions:

• did 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?

Particularly, the last suggestion (new env) was useful for people experiencing the same issue (ie. #341).

Hi!

• yes I did try the hard-reloading, but it is not working.
• I saw that making a new environment solve the problem for the other user with the same problem... but I don't know how to make a fresh environment !? Does it mean re-install all anaconda ? As I said above, I also try on a linux machine, with a fresh install of anaconda3, and direct conda install of Rise, without other extensions, and the problem is the same.

I tried in chrome and Firefox

I don't know how to make a fresh environment !? Does it mean re-install all anaconda ?

You can create a new environment with the conda create -n foo command. Then you activate that env and install rise ok it. You should not need to reinstall anaconda.

As I said above, I also try on a linux machine, with a fresh install of anaconda3, and direct conda install of Rise, without other extensions, and the problem is the same.

OK, let's focus on this setup. Do you have the same error in the js console? Can you report the browsers versions?

[NGillet]

it works when I made the new env on the mac and on linux too.

Wow, great it is working. Can you report the notebook version in the NOT working environment (which I presume is the root env) and in the working environment?
