ModuleNotFoundError: No module named 'pyproj'

When solving [Ex5-Mapping-Curie-depth-EMAG2.ipynb] through Binder, at the interpolation onto grid projection step, I got this error:

ModuleNotFoundError Traceback (most recent call last) in 7 8 # extent on the sphere (WGS84) ----> 9 extent_sphere = mapping.convert_extent(extent_grid, epsg_in=2157, epsg_out=4326) 10 11 # map extent - should be narrower than extent_sphere

Could you please debug this?
