Every time if I wanted to delete an Alembic file that is opened in the current Houdini session, it'd stop me from from doing that because Houdini is still using the file, even if I deleted the alembic node, etc.

Is there a way to ‘de-attach’ the alembic so that I can delete the file without closing the Houdini session and re-open it again? Maybe with python?

Thanks.
