save_core_families

t3toolbox.backend.common.save_core_families(file, families)

def save_core_families(
        file,      # path or open file object to write the .npz to
        families,  # sequence of core-families, each a sequence of arrays
) -> None:

Save a sequence of core-families (each a sequence of arrays) to a .npz file.

Uses 'f{family_index}_{core_index}' keys so load_core_families() can regroup them. Shared by the frontend save methods (T3Frame, T3Variations, T3Tangent).

Return type:

None
