Cannot add Jupyter notebook extension

[mcmartins]

:D no problem @nathancarter! I believe I have introduced some bugs in the version you installed :P, so in the next days I'll release a fully working version and advise you to use it.
Once again, thanks for trying this out.

Hi @nathancarter, humm something happened after release v0.5.6... Will investigate and come back to you ASAP...

[nathancarter]

There seems to be an additional installation step here before enabling nbextensions now. I tried doing that for jupyter_francy, but couldn't seem to get the right combination of commands together. Just mentioning this as a potential place to start hunting for the problem.

[nathancarter]

Update:

The following procedure seems to install correctly:

$ jupyter nbextension install /path/to/where/pip/puts/your/python/stuff/jupyter_francy/
$ jupyter nbextension enable jupyter_francy/nbextension/extension --sys-prefix

But then when I run the notebook, I get script errors in require calls from francy. I tried it with index instead of extension, but with the same result.

@nathancarter, thanks for the update. I messed up with something at some point... Since I'm working on a new feature to allow multiple renderers and did alot of changes, I've decided to upload the latest version into pypi.

I've just tried to install everything from scratch and it works fine. Make sure you remove all the pip francy modules installed, remove the extension from jupyter and then run:

(test-extension) mcmartins@local:~$ pip install jupyter_francy
(test-extension) mcmartins@local:~$ jupyter nbextension enable --py --sys-prefix jupyter_francy

Will install version 0.9.0.

It's in pretty early stage but I'll release a final version in the next days.

[nathancarter]

Thanks for helping out with this! Unfortunately, I still have some problems.

I think I have successfully removed the old jupyter_francy, as you can see here:

$ jupyter nbextension list
Known nbextensions:
  config dir: /Users/nathan/.jupyter/nbconfig
    notebook section
      gap-mode/main  enabled
      - Validating: OK
      test-extension/main  enabled
      - Validating: OK

But when I attempt to install the new one, this happens:

$ sudo pip install jupyter_francy
[many bits of console output omitted here]
Installing collected packages: jupyter-francy
Successfully installed jupyter-francy-0.9.0a0
$ jupyter nbextension enable --py --sys-prefix jupyter_francy

Do we need the separate install step mentioned above, or am I barking up the wrong tree?

Thank you again.

[mcmartins]

Hi @nathancarter , no worries. I really appreciate that you're trying the module out :)
That is strange, jupyter cannot find the module so I'm wondering if you have multiple versions of python installed? Perhaps pip is pointing to python2? Can you please check if you have a pip3? Jupyter requires python 3 and indeed I can see it in the logs (.../libexec/lib/python3.7/...), but could the jupyter_francy extension been installed on the python2 environment instead?

[nathancarter]

Ah, that's it! My apologies for my lack of knowledge of my own configuration. Replacing pip with pip3 made it possible to install jupyter_francy after that, and I can confirm that launching jupyter with a GAP kernel correctly loads the jupyter_francy module (based on what the console says). I haven't tried to use it yet, but this step is all set! Thank you very much.
