Jupyter_contrib_nbextensions: Setup problem? ImportError: No module named jupyter_nbextensions_configurator.application

[Kevin-McIsaac]

After pulling from the main branch when I run ./setup.py install I get the error ImportError: No module named jupyter_nbextensions_configurator.application (see full output below).

When I use the About menu item it says I'm running notebook server is 4.2.1. If I open a shell and run jupyter --version it says 4.1.0. Note sure if this is useful but
jupyter --config-dir
/home/ec2-user/.jupyter

jupyter --data-dir
/home/ec2-user/.local/share/jupyter

ugh, sorry, this is my fault, introduced in #644, and related to our non-standard setup script. Essentially one of the requirements is required in order to _run_ the setup script, not just for use _after_ it's run. You can fix it by pip-installing the module in question jupyter_nbextensions_configurator, but I'll also push a fix in a minute or so.

[jcb91]

ok, should be done - let me know!

[Kevin-McIsaac]

I reran setup after pulling the changed but got the same error. I checked setup and I have the modified version that requires .

I use pip to install jupyter_nbextensions_configurator and the setup now works and nbextensions page is working again. I did note that in the nbextensions page the extention config/config_menu/main is greyed out and marked possibly incompatible, that the nbextentions page is not in the note book edit menu and not on a tab on the dash board.

[jcb91]

oh bummer, I guess I've misunderstood how setup_requires works, then.

The other remaining problems you note seem also to stem from the transition to jupyter_nbextensions_configurator.

the extention config/config_menu/main is greyed out

this may be the old uri still enabled in config (see below). If you allow configuring 'incompatible' extensions, you ought to be able to check what it says about compatibility?

the nbextentions page is not in the note book edit menu

That was provided by the config menu extension, which was removed from this repo as it's now provided by jupyter_nbextensions_configurator. You'll need to re-enable it from the config page, as its require uri has changed (from config/config_menu/main to nbextensions_configurator/config_menu/main).

not on a tab on the dash board

this is not enabled by default - did you enable the Nbextensions dashboard tab nbextension?

[Kevin-McIsaac]

1. Duh, didn't realise I need to enable Nbextensions dashboard tab. Enabled that and it works fine!

2. I turned off "disable configuration for extensions without explicit compatibility" but the edit menu item is still missing. The extension has this message

   config/config_menu/main
   This extension is enabled in the notebook json config, but doesn't provide a yaml file to tell us how to configure it. You can still enable or disable it from here, though.
   section: notebook
   compatibility: ?.x

My thought is this config/config_menu/main can be deprecated in favor of Nbextensions dashboard tab

[Kevin-McIsaac]

1. Duh, didn't realise I need to enable Nbextensions dashboard tab. Enabled that and it works fine!
2. I turned off "disable configuration for extensions without explicit compatibility" but the edit menu item is still missing. I then noticed a new extension called "Nbextensions edit menu item", which provide this functionality. Suggest config/config_menu/main be removed

[jcb91]

Duh, didn't realise I need to enable Nbextensions dashboard tab

others have made the same assumption, so I think eventually it will make sense to have it enabled by default. For now, I don't have the mechanism written to do that reliably, but I'm working on stuff that will provide it as a side-effect.

Yeah, what's going on here is that the installation of the new version doesn't take account of the fact that config/config_menu/main actually _has_ been removed, so its enabled status remains in the notebook config files. Really, I suppose what should happen here is a migration of the enabled status from the old require uri to the new one, but again, this would rely on code I haven't fully written yet. Or perhaps I should have kept the name the same, so it was clearer what was going on 😕

I have a similar error during setup. I am installing IPython-notebook-extensions for the first time, and this is the error message I get:

$ ./setup.py install

Hope this helps.

This should (hopefully) have been fixed in https://github.com/ipython-contrib/IPython-notebook-extensions/commit/b148511713b0dd2332e8730fe18e094ed5e64262, so hopefully doesn't happen with latest repo version - can we close this?

[gcbgit]

I'm still getting the error after doing a pull about 5 min ago, so I don't think it's been fixed yet. I'm assuming the fix was meant to be in b1485117?

This after a 'conda update --all', so iPython, Jupyter and the rest are at their anaconda latest.

Doing a 'pip install jupyter_nbextensions_configurator' before ./setup.py install seemed to do the trick.

Ok, so it isn't fixed, and this should stay open.

Doing a 'pip install jupyter_nbextensions_configurator' before ./setup.py install seemed to do the trick.

Yes, it would. Essentially what's going on is that the jupyter_nbextensions_configurator module is used in the setup.py script to enable itself. However, pip/setuptools doesn't install a package's runtime dependencies _before_ attempting to install the package, so the setup.py script fails if jupyter_nbextensions_configurator is missing. I attempted to fix this in b148511713b0dd2332e8730fe18e094ed5e64262 using setuptools' setup_requires field, but it doesn't seem to have worked. I'm not completely sure how setup_requires options are intended to work, so I guess I should investigate (should _have_ investigated before assuming it would solve the problem 😢).

[jcb91]

for reasons I still don't understand, it seems that although running

python setup.py install

fails because of the missing jupyter_nbextensions_configurator, running

 `pip install .`

respects the setup_requires kwarg, and install correctly. Weird.

[jcb91]

Closing, as this should now be fixed (or rather, avoided) by our shiny new two-part installation method. As always, reopen if I'm wrong!

I am getting this error in the terminal after starting the notebook (rather than at installation):

    ImportError: No module named 'jupyter_nbextensions_configurator'

Should this be a separate issue, or should this be re-opened?

Running the current master on Python 3.5 (OS X).

[jcb91]

@fonnesbeck weird, seems like for some reason the configurator hasn't been installed correctly. However, this should probably go to a new issue, as it seems to be a different root cause. For the new issue, please add your install method (conda, pip etc) & any output that you get from the install.

python -m pip install --user jupyter_contrib_nbextensions solve this problem

@eromoe

Thanks ! It's helpful for me

Hello,
you mentioned Configurable nbextension: "disable configuration for nbextensions without explicit compatibility".
I cannot find a answer how to disable it via command line instead of clicking the button.
What do I miss?

One last comment to this in the case that you are using Anaconda to virtual env your Python install and you are also getting the error @fonnesbeck enumerates above: _Re-source your conda environment_. The easiest way to do that is open another window and your environment will reload. Then, shazaam!
