Lesson 1 using paperspace: Failed to display Jupyter Widget of type HBox

(alex kelly) #1


I’ve just started the course and when i’ve ran the jupyter it says “Failed to display Jupyter Widget of type HBox.”, is this something i can ignore or not?

I’ve tried to fix it using the suggestions on the link “https://ipywidgets.readthedocs.io/en/stable/user_install.html” but it comes back with OK for pip installed and asked for downgrading blas, numpy, scipy which i canceled out as i thought that might break something else. Anyone have any ideas?

Failed to display Jupyter Widget of type HBox.

If you’re reading this message in the Jupyter Notebook or JupyterLab Notebook, it may mean that the widgets JavaScript is still loading. If this message persists, it likely means that the widgets JavaScript library is either not installed or not enabled. See the Jupyter Widgets Documentation for setup instructions.

If you’re reading this message in another frontend (for example, a static rendering on GitHub or NBViewer), it may mean that your frontend doesn’t currently support widgets.

found the issue. Just needed to run the entries in jupyter - rookie mistake.
