Hey!
I’m following this tutorial Building a Custom Widget - Email widget — Jupyter Widgets 8.0.0rc0 documentation (ipywidgets.readthedocs.io)
When I get to the Test part and try to execute this code in Jupyter
from ipyemail import Email
Email()
I get an error from Jupyter Lab saying Error displaying widget: model not found or in Jupyter Classic, after opening up browser dev tools, I get multiple errors:
Could not instantiate widget
Error: Could not create a model.
Couldn't process kernel message Class EmailModel not found in module jupyter-email
Uncaught (in promise) Class EmailModel not found in module jupyter-email
I followed instructions 1:1 and do have Class EmailModel in my widgets.ts.
Also the ‘Hello World’ example worked fine, before renaming the classes as per instructions.
Any help would be appreciated.
