Installation on google colab

[kHarshit]

Hi,

I'm trying to use this extension on google colab, however, it doesn't work.

Steps I'm following:

# install nbextensions
!pip install jupyter_contrib_nbextensions
# install js and CSS
!jupyter contrib nbextension install --user
# install ipydex
`!pip install ipydex`
# enable ipydex
`!jupyter nbextension enable ipydex.displaytools`

It doesn't get enabled, the error I'm getting:

Enabling notebook extension ipydex.displaytools...
Paths used for configuration of notebook: 
    	/root/.jupyter/nbconfig/notebook.json
Paths used for configuration of notebook: 
    	
      - Validating: problems found:
        - require?  X ipydex.displaytools
Paths used for configuration of notebook: 
    	/root/.jupyter/nbconfig/notebook.json

However, if I try enabling another extension, say, hinterland or codefolding, it works:

!jupyter nbextension enable codefolding/main
Enabling notebook extension codefolding/main...
Paths used for configuration of notebook: 
    	/root/.jupyter/nbconfig/notebook.json

      - Validating: OK

    	/root/.jupyter/nbconfig/notebook.json

I tried the following in colab: !pip install ipydex and then %load_ext ipydex.displaytools and the extension worked. @kHarshit could you try that and report? If that works for you, you can close the issue.

I had not yet heard about jupyter_contrib_nbextensions before and I am currently not aware what exactly !jupyter nbextension ... does. The extension ipydex.displaytools uses the vanilla extension loading mechanism provided by jupyter notebook.

However, jupyter_contrib_nbextensions seems interesting and I should have a deeper look.

Yes, it works using %load_ext, thanks.
