widget support on Kaggle kernel

I’m unable to get my widget (https://github.com/ismms-himc/clustergrammer2) to work in Kaggle (link to public kaggle notebook https://www.kaggle.com/cornhundred/kernel064927894e). I’m seeing the following error that begins with Could not instantiate widget:

I’m using the following commands to pip install the widget:

!pip install ipywidgets
!pip install clustergrammer2
!jupyter nbextension enable --py --sys-prefix widgetsnbextension
!jupyter nbextension enable --py --sys-prefix clustergrammer2

I commented on someone facing the same issue on Kaggle under product-feedback https://www.kaggle.com/product-feedback/42782

I think we can just raise a question on their Q&A section. Someone already asked about Jupyter widgets here (https://www.kaggle.com/questions-and-answers/33450) and here (https://www.kaggle.com/cavendish/interactive-widgets-in-a-notebook).

It actually seems to be very easy to get the widget to run in the notebook (see notebook https://www.kaggle.com/cornhundred/clustergrammer2-viz-stoeckius-et-al-2017). You just have to go to settings (on the right panel), Packages: Install, and just give the name of the custom package. I did not even need to do the usual jupyter nbextension enable --py --sys-prefix widgetsnbextension step.

On a related note, I could not get the widget working on Google’s colab.

If widgets in kaggle works as easily as it seems to (and especially if we can embed the widgets into the static html notebooks) then it will be very useful for our group. Kaggle offers computers with 16GB of ram, private projects, easy version controlling, etc.
