jupyter_nbextensions_configurator server extension not visible

[san089]

Hi Team,

As mentioned, I am not able to see the nbextension server extension on the UI in the browser.

I followed the installation instructions. 1.) Ran a conda installation -> "conda install -c conda-forge jupyter_nbextensions_configurator". 2.) Installation was successful, but after opening jupyter notebook I am not able to see the nbextension server extension on the UI. Link - "http://localhost:8888/tree/nbextensions" 2.) Also I am able to enable and disable the extension from CLI using "jupyter nbextension enable hinterland/hinterland". The command works perfect and I am able to use the hinterland extension.

I did try the installation through cloning the git repository. I am able to successfully install the nbextension but again not able to see the server extension on the UI.

Conda Version - 4.5.12 Python Version - 3.7.1 Browser - Google Chrome

same issue here, even after enabling the extension, relaunching Jupyter , nothing is displayed

[michaelaye]

Same here. I upgraded to 0.4.1 in the hope it was solving this issue but it still does not.

Neither does the tab appear:

nor does the link to https://localhost:8888/tree/nbextensions work.

Same versions as OP, running on the Mac platform.

Did you enable the configurator using jupyter nbextensions_configurator enable --user ? Do you see in the log when starting the notebook [jupyter_nbextensions_configurator] enabled 0.4.1 ?

[michaelaye]

yes:

$ jupyter notebook .                                                                                                  (py37)
[I 14:24:43.163 NotebookApp] [nb_conda_kernels] enabled, 5 kernels found
[I 14:24:43.711 NotebookApp] Loading IPython parallel extension
[I 14:24:43.751 NotebookApp] [jupyter_nbextensions_configurator] enabled 0.4.1

[michaelaye]

For reproducing, one might need the notebook version I tried it with: 5.7.4.

[juhasch]

Can you check what happens when browse to view-source:http://localhost:8888/nbextensions/nbextensions_configurator/tree_tab/main.js (adjust this if you use another server or port). You should see a Javascript file and line 3 should be var $ = require('jquery');

[michaelaye]

it does:

define(function (require, exports, module) {
    "use strict";

    var $ = require('jquery');

[juhasch]

OK, so does http://localhost:8888/nbextensions work ? If yes, check if you have activated the Nbextensions dashboard tab extension.

[michaelaye]

Ah, I realize I clicked on above link with the default port while I have a different port.

So, that link does work sporadically, but not at all like on notebook 5.6, where I get the whole list of available extensions. (Note, I'm using https, in case that matters). Here's what I see, when I go to the link the first time with notebook 5.7.4:

When I reload, it shows like this:

and when I reload again, it sporadically goes away, showing a blank page, or comes back again.

I'm unaware of the dashboard tab extension, but I'm guessing it's being activated by the conda package, because when I change the notebook to 5.6, everything is fine, the tab is there as well:

(note also the tree filter extension working again in this screenshot, which isn't the case for notebook=5.7.4), the list of nbextensions is shown at the link above:

[juhasch]

I tried it on a Mac with Anaconda and notebook 5.7.4 in a fresh environment. Works fine here. I don't use https. Do you get any errors in the Javascript log in the browser or in the notebook log when you start it with the --debug option ?

[michaelaye]

Confirmed, a new testing environment with the minimum required to work also works here with 5.7.4, using my https configuration. I will now:

• reinstall my large env and check if it works there.
• If not, I will successively install my packages in the testing environment to find out when it breaks.

I'll get back to you, thanks!

[michaelaye]

ok, after noticing that your package doesn't have a requirement on jupyter_contrib_nbextensions, I tried that first, and bingo, it's that which blocks it all. I guess that's related to this issue I created over there a while ago, where you also once commented? https://github.com/ipython-contrib/jupyter_contrib_nbextensions/issues/1356

[michaelaye]

ah, that's the one where I'm waiting for the fix to be released! ;)

[san089]

Did check out the [https://github.com/ipython-contrib/jupyter_contrib_nbextensions/issues/1356]() it looks like the problem in my case is caused by jqueryui . If I check [http://localhost:8888/nbextensions/nbextensions_configurator/tree_tab/main.js]() I got

define(function (require, exports, module) {
    "use strict";

    var $ = require('jqueryui');

which is using jqueryui and as per your comment in issue #1356 it seems the notebook 5.7 does not include jqueryui. Not sure but maybe this is the issue. NOTE: I am using the notebook on window 10. notebook version - 5.7.4

Hi All,

Spend the last 4 hours trying to install this. But could not view the extensions. I am writing all the steps followed. Could you please tell me if I missed something.

Specs: Win10, FF 64, Py3.6.6, all 64 bit. Conda Version - 4.5.12.

1) Ran a conda installation -> "conda install -c conda-forge jupyter_nbextensions_configurator".

2.) Installation was successful, but after opening jupyter notebook I can only see these extensions:

whereas, I was hoping to see something like this:

In the browser console, I do not see any error messages. I see 3 warnings:

3.) I have also tried enabling the configurator using jupyter nbextensions_configurator enable --user ?

4.) I am not able to enable and disable the extension from CLI using "jupyter nbextension enable hinterland/hinterland".

[itegmark]

prasunkgupta, I got the same problem, couldn't find the fix

[itegmark]

prasunkgupta, I solvedit with this:

conda remove jupyter_nbextensions_configurator 
conda install -c conda-forge jupyter_nbextensions_configurator
conda install -c conda-forge jupyter_contrib_nbextensions

[prasunkgupta]

@ginsent - It Works! Thank you.

[yc1999]

@ginsent it works,thanks!

[AnshumanFauzdar]

prasunkgupta, I solvedit with this:

conda remove jupyter_nbextensions_configurator 
conda install -c conda-forge jupyter_nbextensions_configurator
conda install -c conda-forge jupyter_contrib_nbextensions

I enabled hinterland but in jupyter lab it is not working! Where am I getting it wrong? In notebook it is working fine!

[kavyajeetbora]

This is working for me. Note: Type these command in the anaconda terminal
