error :module 'pygsp.graphs' has no attribute 'SphereHealpix'
I checked the documentation of pygap and did not find the function pg.graphs.SphereHealpix and pg.graphs.SphereEquiangular pg.graphs.SphereCubed . and How do I run these codes?

Thanks for your interest. The SphereHealpix, SphereEquiangular, and SphereCubed aren't yet merged in the main branch of the PyGSP. Try pip install git+https://github.com/epfl-lts2/pygsp@sphere-graphs.

If pip tells you that PyGSP is already install try: pip install git+https://github.com/epfl-lts2/pygsp@sphere-graphs --force
