I need to import alembic geometry in houdini. So far what i've come across is

import _alembic_hom_extensions as abc
print abc.alembicGetSceneHierarchy(“/job/HOME/nsinghai/my_jobs/layout_geo.abc”, “/”)

This gives a list of all meshes within the file. It does not import the geometry. I need python command to import the
alembic geometry into houdini scene file.

How is it possible ?

Houdini doesn't import geometry directly. Houdini must use nodes to represent any geometry in the scene. If the import process must be scripted, node creation can be done with python.

The file/alembic geometry operator (SOP) nodes as well as the Alembic Hierarchy Object operator node can read alembic files.

Start with the basics:
