When you run InteractiveMarkerSelection with no visuals (i.e., visuals=[]), you get an IndexError

im = pr.markers.interactive.InteractiveMarkerSelection(adata, cife, [])
im.show()

Gives the following IndexError

    134     def draw_visual(self, visual_ind):
    135         """Lazily draw visualization"""

    137             self.visuals[visual_ind].redraw(self.top_genes, self.featsel.S)
    138             self.visuals_drawn[visual_ind] = True
