In a future version, a new instance will always be created and returned.  Meanwhile, this warning can be suppressed, and the future behavior ensured, by passing a unique label to each axes instance.

This seems to be caused by matplotlib API change. From [1]:

colorbar.ColorbarBase.get_cmap (use ScalarMappable.get_cmap instead)

However, apart from that, I have no clue how to adapt to this change.
