Describe the bug
I am running the standard vignette provided in the SCENIC plus tutorial, in jupyter notebook
When I am running plot_topic I get the error ValueError: Unable to determine Axes to steal space for Colorbar. Either provide the *cax* argument to use as the Axes for the Colorbar, provide the *ax* argument to steal space from it, or add *mappable* to an Axes.
This similar error seems to be related to issues with matplotlib and was described , shap/shap#2721
It was recommend to install matplotlib version 3.6 but this isnt fixing it in my case
