Jupyter Notebook: Widget Javascript Not Detected

Question: I installed python3 and jupyter notebook using pip3 in MacOs 10.9. When I try to run the widget it gives error that there is no javascript widget. I have python3 and R ke

Solution 1:

Run the following command: jupyter nbextension enable --py --sys-prefix widgetsnbextension, then restart the kernel in Jupyter should do the trick.

Solution 2:

I used the following commands successfully with Jupyter, Mac OS, Python 3.6, and Anaconda. The first command gets the latest version of ipywidgets at this time (version 7.0).

conda install -c conda-forge ipywidgets

jupyter nbextension enable --py widgetsnbextension

Solution 3:

I faced the same problem and after running the command:jupyter nbextension enable --py --sys-prefix widgetsnbextension, the prompt should appear:

>Enabling notebook extension jupyter-js-widgets/extension...

- Validating: ok. Refresh your jupyter notebook and the widgets worked.

Solution 4:

Probably the best way, at least it worked for me: reinstall the ipywidgets and widgetsextension and it should work.

pip uninstall ipywidgets widgetsnbextension

pip install ipywidgets

jupyter nbextension enable --py--sys-prefix widgetsnbextension

Solution 5:

This solved it for me:

jupyter labextension install @jupyter-widgets/jupyterlab-manager
