Loading extensions through HTMLManager?

JupyterLab
1

I’ve created a front-end widget manager by extending from HTMLManager and setup a connection to a running jupyter kernel (with python -m notebook --no-browser), however, when I try to get the kernel to parse some plotting code using Plotly, I get the error message

Could not load module plotlywidget@^0.10.0

The code works if I run it in a normal jupyter notebook.

I’m guessing that it’s because setting up the kernel manager manually isn’t loading the Jupyter extensions (plotlywidget in this case).

Is there any way that I can get the kernel manager to load extensions?

Thanks in advance.

You’ll need to overload the loadClass method for the kernel manager to make the extension available. You can search the ipywidgets codebase for loadClass to see some examples.
