%matplotlib widget not Working in Jupyter Lab
One of the best features of Jupyter Lab is the command that makes plots interactive: %matplotlib widget
I recently (Aug 2021) setup a Digital Ocean droplet to be a Jupyter Lab notebook server. I am aware that there are other ways of doing this: mybinder.org, Google colab, etc… But I could not get them working and could not look “under the hood” to figure out what was wrong.
I followed the instructions here. Things went pretty smoothly… except my plots stopped showing. Instead I got some text like:
Canvas(toolbar=Toolbar(toolitems=[('Home', 'Reset original view', 'home', 'home'),
After googling, I found that this was a problem in 2019. None of those solutions worked. Then I found a solution for Jupyter Lab 3.x. Certainly my new install would have a semi-up-to-date version… Not so. The Jupyter Lab version was 1.2.6.
After:
conda update jupyterlab%matplotlib widget started working.
I did some other fiddling before that to install a recent version of nodejs. I am not sure if that also helped make this work. But I know that updating jupyterlab is part or all of the solution.
