ValueError: Re-registering the builtin cmap 'Set1' is not allowed.

Hi, I was learning the turtual about this : https://spateo-release.readthedocs.io/en/latest/tutorials/notebooks/5_cluster_digitization/5_borderline_digitization.html

But I get this erro information

st.pl.space(adata, space = "cellbin_spatial", color=['score'], pointsize=0.2,cmap="Set1", show_legend="upper left")

I experienced the same error and guess it has something to do with the matplotlib version. As a workaround I cloned this GitHub repo and commented out this line 600 in the utils.py file:

# mpl.colormaps.register(name=cmap_.name, cmap=cmap_, force=True)

I also had to change line 788 in the same file to this:

cb._draw_all()

Afterwards I could install the package using pip install . and plotting worked.

Hope this works for you as well!
