6 years ago Same problem here. I'm running Ubuntu, Anaconda, Jupyter, and get this error:
[IPKernelApp] ERROR | No such comm target registered: jupyter.widget.version
The issue was resolved by restarting Jupyter.
**I wrote the interact for import from ipywidgets and it doesn't work ,
First I wrote in the jupyter nbextension enable --py widgetsnbextension in promt Not working anymore Second I also try to update the ipywidgets version still fail Third i try to delete the files in C:\Users\user.jupyter\nbconfig fail again**
