The functions have changed in v0.10.0 (moved to pvlib.bifacial.utils and made public). In versions prior to v0.10.0, the functions are in pvlib.bifacial.infinite_sheds and are private (start with "_").

I think you want either pvlib.bifacial.utils.vf_ground_sky_2d (fraction of sky dome visible at a point) or pvlib.bifacial.utils.vf_ground_sky_2d_integ (averaged over a range of points).
